Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

Many improvements to the Platform base class and subclasses. The base Platform class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563

Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

Many improvements to the Platform base class and subclasses. The base Platform class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable.

Added support for inlined stack frames being represented as real stack frames which is now on by default. Frames are gotten from the unwinder as concrete frames, then if inline frames are to be shown, extra information to track and reconstruct these frames is cached with each Thread and exanded as needed.

This allows for two frames to shared the same call frame address, yet differ only in inline height. Fixed setting breakpoint by address to not require addresses to resolve.

Many improvements to the Platform base class and subclasses. The base Platform class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563

LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide an interface to a local or remote debugging platform. By default each host OS that supports LLDB should be registering a "default" platform that will be used unless a new platform is selected. Platforms are responsible for things such as: - getting process information by name or by processs ID - finding platform files. This is useful for remote debugging where there is an SDK with files that might already or need to be cached for debug access. - getting a list of platform supported architectures in the exact order they should be selected. This helps the native x86 platform on MacOSX select the correct x86_64/i386 slice from universal binaries. - Connect to remote platforms for remote debugging - Resolving an executable including finding an executable inside platform specific bundles (macosx uses .app bundles that contain files) and also selecting the appropriate slice of universal files for a given platform. So by default there is always a local platform, but remote platforms can be connected to. I will soon be adding a new "platform" command that will support the following commands: (lldb) platform connect --name machine1 macosx connect://host:port Connected to "machine1" platform. (lldb) platform disconnect macosx This allows LLDB to be well setup to do remote debugging and also once connected process listing and finding for things like: (lldb) process attach --name x<TAB> The currently selected platform plug-in can now auto complete any available processes that start with "x". The responsibilities for the platform plug-in will soon grow and expand. llvm-svn: 127286

Added more platform support. There are now some new commands: platform status -- gets status information for the selected platform platform create <platform-name> -- creates a new instance of a remote platform platform list -- list all available platforms platform select -- select a platform instance as the current platform (not working yet) When using "platform create" it will create a remote platform and make it the selected platform. For instances for iPhone OS debugging on Mac OS X one can do: (lldb) platform create remote-ios --sdk-version=4.0 Remote platform: iOS platform SDK version: 4.0 SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0" Not connected to a remote device. (lldb) file ~/Documents/a.out Current executable set to '~/Documents/a.out' (armv6).

Once connected to a remote platform the OS version might change which means we will need to update our dependecies. Also once we run, we will need to match up the actualy binaries with the actualy UUID's to files in the SDK, or download and cache them locally. This is just the start of the remote platforms, but this modification is the first iteration in getting the platforms really doing something. llvm-svn: 127934

Many improvements to the Platform base class and subclasses.

Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information.

I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563

Added the ability to get the min and max instruction byte size for an architecture into ArchSpec: uint32_t ArchSpec::GetMinimumOpcodeByteSize() const; uint32_t ArchSpec::GetMaximumOpcodeByteSize() const; Added an AddressClass to the Instruction class in Disassembler.h. This allows decoded instructions to know know if they are code, code with alternate ISA (thumb), or even data which can be mixed into code. The instruction does have an address, but it is a good idea to cache this value so we don't have to look it up more than once. Fixed an issue in Opcode::SetOpcodeBytes() where the length wasn't getting set. Changed: bool SymbolContextList::AppendIfUnique (const SymbolContext& sc); To: bool SymbolContextList::AppendIfUnique (const SymbolContext& sc, bool merge_symbol_into_function); This function was typically being used when looking up functions and symbols. Now if you lookup a function, then find the symbol, they can be merged into the same symbol context and not cause multiple symbol contexts to appear in a symbol context list that describes the same function. Fixed the SymbolContext not equal operator which was causing mixed mode disassembly to not work ("disassembler --mixed --name main"). Modified the disassembler classes to know about the fact we know, for a given architecture, what the min and max opcode byte sizes are. The InstructionList class was modified to return the max opcode byte size for all of the instructions in its list. These two fixes means when disassemble a list of instructions and dump them and show the opcode bytes, we can format the output more intelligently when showing opcode bytes. This affects any architectures that have varying opcode byte sizes (x86_64 and i386). Knowing the max opcode byte size also helps us to be able to disassemble N instructions without having to re-read data if we didn't read enough bytes. Added the ability to set the architecture for the disassemble command. This means you can easily cross disassemble data for any supported architecture. I also added the ability to specify "thumb" as an architecture so that we can force disassembly into thumb mode when needed. In GDB this was done using a hack of specifying an odd address when disassembling. I don't want to repeat this hack in LLDB, so the auto detection between ARM and thumb is failing, just specify thumb when disassembling: (lldb) disassemble --arch thumb --name main You can also have data in say an x86_64 file executable and disassemble data as any other supported architecture: % lldb a.out Current executable set to 'a.out' (x86_64). (lldb) b main (lldb) run (lldb) disassemble --arch thumb --count 2 --start-address 0x0000000100001080 --bytes 0x100001080: 0xb580 push {r7, lr} 0x100001082: 0xaf00 add r7, sp, #0 Fixed Target::ReadMemory(...) to be able to deal with Address argument object that isn't section offset. When an address object was supplied that was out on the heap or stack, target read memory would fail. Disassembly uses Target::ReadMemory(...), and the example above where we disassembler thumb opcodes in an x86 binary was failing do to this bug. llvm-svn: 128347

Many improvements to the Platform base class and subclasses. The base Platform class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information.

There are now to new "settings set" variables that live in each debugger instance: settings set frame-format <string> settings set thread-format <string> This allows users to control the information that is seen when dumping threads and frames. The default values are set such that they do what they used to do prior to changing over the the user defined formats. This allows users with terminals that can display color to make different items different colors using the escape control codes. A few alias examples that will colorize your thread and frame prompts are: settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n' settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n' A quick web search for "colorize terminal output" should allow you to see what you can do to make your output look like you want it. The "settings set" commands above can of course be added to your ~/.lldbinit file for permanent use.

Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up doing was: - Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple to give us the machine type from llvm::Triple::ArchType. - There is a new ArchSpec::Core definition which further qualifies the CPU core we are dealing with into a single enumeration. If you need support for a new Core and want to debug it in LLDB, it must be added to this list. In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. llvm-svn: 126278

In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. llvm-svn: 126278

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

Put more smarts into the RegisterContext base class. Now the base class has a method: void RegisterContext::InvalidateIfNeeded (bool force); Each time this function is called, when "force" is false, it will only call the pure virtual "virtual void RegisterContext::InvalideAllRegisters()" if the register context's stop ID doesn't match that of the process. When the stop ID doesn't match, or "force" is true, the base class will clear its cached registers and the RegisterContext will update its stop ID to match that of the process. This helps make it easier to correctly flush the register context (possibly from multiple locations depending on when and where new registers are availabe) without inadvertently clearing the register cache when it doesn't need to be. Modified the ProcessGDBRemote plug-in to be much more efficient when it comes to: - caching the expedited registers in the stop reply packets (we were ignoring these before and it was causing us to read at least three registers every time we stopped that were already supplied in the stop reply packet). - When a thread has no stop reason, don't keep asking for the thread stopped info. Prior to this fix we would continually send a qThreadStopInfo packet over and over when any thread stop info was requested. We now note the stop ID that the stop info was requested for and avoid multiple requests. Cleaned up some of the expression code to not look for ClangExpressionVariable objects up by name since they are now shared pointers and we can just look for the exact pointer match and avoid possible errors. Fixed an bug in the ValueObject code that would cause children to not be displayed. llvm-svn: 123127

Added new lldb_private::Process memory read/write functions to stop a bunch of duplicated code from appearing all over LLDB: lldb::addr_t Process::ReadPointerFromMemory (lldb::addr_t vm_addr, Error &error); bool Process::WritePointerToMemory (lldb::addr_t vm_addr, lldb::addr_t ptr_value, Error &error); size_t Process::ReadScalarIntegerFromMemory (lldb::addr_t addr, uint32_t byte_size, bool is_signed, Scalar &scalar, Error &error); size_t Process::WriteScalarToMemory (lldb::addr_t vm_addr, const Scalar &scalar, uint32_t size, Error &error); in lldb_private::Process the following functions were renamed: From: uint64_t Process::ReadUnsignedInteger (lldb::addr_t load_addr, size_t byte_size, Error &error); To: uint64_t Process::ReadUnsignedIntegerFromMemory (lldb::addr_t load_addr, size_t byte_size, uint64_t fail_value, Error &error); Cleaned up a lot of code that was manually doing what the above functions do to use the functions listed above. Added the ability to get a scalar value as a buffer that can be written down to a process (byte swapping the Scalar value if needed): uint32_t Scalar::GetAsMemoryData (void *dst, uint32_t dst_len, lldb::ByteOrder dst_byte_order, Error &error) const; The "dst_len" can be smaller that the size of the scalar and the least significant bytes will be written. "dst_len" can also be larger and the most significant bytes will be padded with zeroes. Centralized the code that adds or removes address bits for callable and opcode addresses into lldb_private::Target: lldb::addr_t Target::GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const; lldb::addr_t Target::GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const; All necessary lldb_private::Address functions now use the target versions so changes should only need to happen in one place if anything needs updating. Fixed up a lot of places that were calling : addr_t Address::GetLoadAddress(Target*); to call the Address::GetCallableLoadAddress() or Address::GetOpcodeLoadAddress() as needed. There were many places in the breakpoint code where things could go wrong for ARM if these weren't used. llvm-svn: 131878

Many improvements to the Platform base class and subclasses. The base Platform class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux.

Added new target instance settings for execution settings: Targets can now specify some additional parameters for when we debug executables that can help with plug-in selection: target.execution-level = auto | user | kernel target.execution-mode = auto | dynamic | static target.execution-os-type = auto | none | halted | live On some systems, the binaries that are created are the same wether you use them to debug a kernel, or a user space program. Many times inspecting an object file can reveal what an executable should be. For these cases we can now be a little more complete by specifying wether to detect all of these things automatically (inspect the main executable file and select a plug-in accordingly), or manually to force the selection of certain plug-ins. To do this we now allow the specficifation of wether one is debugging a user space program (target.execution-level = user) or a kernel program (target.execution-level = kernel). We can also specify if we want to debug a program where shared libraries are dynamically loaded using a DynamicLoader plug-in (target.execution-mode = dynamic), or wether we will treat all symbol files as already linked at the correct address (target.execution-mode = static). We can also specify if the inferior we are debugging is being debugged on a bare board (target.execution-os-type = none), or debugging an OS where we have a JTAG or other direct connection to the inferior stops the entire OS (target.execution-os-type = halted), or if we are debugging a program on something that has live debug services (target.execution-os-type = live). For the "target.execution-os-type = halted" mode, we will need to create ProcessHelper plug-ins that allow us to extract the process/thread and other OS information by reading/writing memory. This should allow LLDB to be used for a wide variety of debugging tasks and handle them all correctly. llvm-svn: 125815

Did some work on the "register read" command to only show the first register set by default when dumping registers. If you want to see all of the register sets you can use the "--all" option: (lldb) register read --all If you want to just see some register sets, you can currently specify them by index: (lldb) register read --set 0 --set 2 We need to get shorter register set names soon so we can specify the register sets by name without having to type too much. I will make this change soon. You can also have any integer encoded registers resolve the address values back to any code or data from the object files using the "--lookup" option. Below is sample output when stopped in the libc function "puts" with some const strings in registers: Process 8973 stopped * thread #1: tid = 0x2c03, 0x00007fff828fa30f libSystem.B.dylib`puts + 1, stop reason = instruction step into frame #0: 0x00007fff828fa30f libSystem.B.dylib`puts + 1 (lldb) register read --lookup General Purpose Registers: rax = 0x0000000100000e98 "----------------------------------------------------------------------" rbx = 0x0000000000000000 rcx = 0x0000000000000001 rdx = 0x0000000000000000 rdi = 0x0000000100000e98 "----------------------------------------------------------------------" rsi = 0x0000000100800000 rbp = 0x00007fff5fbff710 rsp = 0x00007fff5fbff280 r8 = 0x0000000000000040 r9 = 0x0000000000000000 r10 = 0x0000000000000000 r11 = 0x0000000000000246 r12 = 0x0000000000000000 r13 = 0x0000000000000000 r14 = 0x0000000000000000 r15 = 0x0000000000000000 rip = 0x00007fff828fa30f libSystem.B.dylib`puts + 1 rflags = 0x0000000000000246 cs = 0x0000000000000027 fs = 0x0000000000000000 gs = 0x0000000000000000 As we can see, we see two constant strings and the PC (register "rip") is showing the code it resolves to. I fixed the register "--format" option to work as expected. Added a setting to disable skipping the function prologue when setting breakpoints as a target settings variable: (lldb) settings set target.skip-prologue false Updated the user settings controller boolean value handler funciton to be able to take the default value so it can correctly respond to the eVarSetOperationClear operation. Did some usability work on the OptionValue classes. Fixed the "image lookup" command to correctly respond to the "--verbose" option and display the detailed symbol context information when looking up line table entries and functions by name. This previously was only working for address lookups. llvm-svn: 129977

For the "target.execution-os-type = halted" mode, we will need to create ProcessHelper plug-ins that allow us to extract the process/thread and other OS information by reading/writing memory.

Did some work on the "register read" command to only show the first register set by default when dumping registers. If you want to see all of the register sets you can use the "--all" option: (lldb) register read --all If you want to just see some register sets, you can currently specify them by index: (lldb) register read --set 0 --set 2 We need to get shorter register set names soon so we can specify the register sets by name without having to type too much. I will make this change soon. You can also have any integer encoded registers resolve the address values back to any code or data from the object files using the "--lookup" option. Below is sample output when stopped in the libc function "puts" with some const strings in registers: Process 8973 stopped * thread #1: tid = 0x2c03, 0x00007fff828fa30f libSystem.B.dylib`puts + 1, stop reason = instruction step into frame #0: 0x00007fff828fa30f libSystem.B.dylib`puts + 1 (lldb) register read --lookup General Purpose Registers: rax = 0x0000000100000e98 "----------------------------------------------------------------------" rbx = 0x0000000000000000 rcx = 0x0000000000000001 rdx = 0x0000000000000000 rdi = 0x0000000100000e98 "----------------------------------------------------------------------" rsi = 0x0000000100800000 rbp = 0x00007fff5fbff710 rsp = 0x00007fff5fbff280 r8 = 0x0000000000000040 r9 = 0x0000000000000000 r10 = 0x0000000000000000 r11 = 0x0000000000000246 r12 = 0x0000000000000000 r13 = 0x0000000000000000 r14 = 0x0000000000000000 r15 = 0x0000000000000000 rip = 0x00007fff828fa30f libSystem.B.dylib`puts + 1 rflags = 0x0000000000000246 cs = 0x0000000000000027 fs = 0x0000000000000000 gs = 0x0000000000000000 As we can see, we see two constant strings and the PC (register "rip") is showing the code it resolves to. I fixed the register "--format" option to work as expected. Added a setting to disable skipping the function prologue when setting breakpoints as a target settings variable: (lldb) settings set target.skip-prologue false Updated the user settings controller boolean value handler funciton to be able to take the default value so it can correctly respond to the eVarSetOperationClear operation. Did some usability work on the OptionValue classes. Fixed the "image lookup" command to correctly respond to the "--verbose" option and display the detailed symbol context information when looking up line table entries and functions by name. This previously was only working for address lookups. llvm-svn: 129977

Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up doing was: - Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple to give us the machine type from llvm::Triple::ArchType. - There is a new ArchSpec::Core definition which further qualifies the CPU core we are dealing with into a single enumeration. If you need support for a new Core and want to debug it in LLDB, it must be added to this list. In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. llvm-svn: 126278

I will make this change soon. You can also have any integer encoded registers resolve the address values back to any code or data from the object files using the "--lookup" option. Below is sample output when stopped in the libc function "puts" with some const strings in registers: Process 8973 stopped * thread #1: tid = 0x2c03, 0x00007fff828fa30f libSystem.B.dylib`puts + 1, stop reason = instruction step into frame #0: 0x00007fff828fa30f libSystem.B.dylib`puts + 1 (lldb) register read --lookup General Purpose Registers: rax = 0x0000000100000e98 "----------------------------------------------------------------------" rbx = 0x0000000000000000 rcx = 0x0000000000000001 rdx = 0x0000000000000000 rdi = 0x0000000100000e98 "----------------------------------------------------------------------" rsi = 0x0000000100800000 rbp = 0x00007fff5fbff710 rsp = 0x00007fff5fbff280 r8 = 0x0000000000000040 r9 = 0x0000000000000000 r10 = 0x0000000000000000 r11 = 0x0000000000000246 r12 = 0x0000000000000000 r13 = 0x0000000000000000 r14 = 0x0000000000000000 r15 = 0x0000000000000000 rip = 0x00007fff828fa30f libSystem.B.dylib`puts + 1 rflags = 0x0000000000000246 cs = 0x0000000000000027 fs = 0x0000000000000000 gs = 0x0000000000000000 As we can see, we see two constant strings and the PC (register "rip") is showing the code it resolves to. I fixed the register "--format" option to work as expected. Added a setting to disable skipping the function prologue when setting breakpoints as a target settings variable: (lldb) settings set target.skip-prologue false Updated the user settings controller boolean value handler funciton to be able to take the default value so it can correctly respond to the eVarSetOperationClear operation. Did some usability work on the OptionValue classes. Fixed the "image lookup" command to correctly respond to the "--verbose" option and display the detailed symbol context information when looking up line table entries and functions by name. This previously was only working for address lookups. llvm-svn: 129977

Added new target instance settings for execution settings: Targets can now specify some additional parameters for when we debug executables that can help with plug-in selection: target.execution-level = auto | user | kernel target.execution-mode = auto | dynamic | static target.execution-os-type = auto | none | halted | live On some systems, the binaries that are created are the same wether you use them to debug a kernel, or a user space program. Many times inspecting an object file can reveal what an executable should be. For these cases we can now be a little more complete by specifying wether to detect all of these things automatically (inspect the main executable file and select a plug-in accordingly), or manually to force the selection of certain plug-ins. To do this we now allow the specficifation of wether one is debugging a user space program (target.execution-level = user) or a kernel program (target.execution-level = kernel). We can also specify if we want to debug a program where shared libraries are dynamically loaded using a DynamicLoader plug-in (target.execution-mode = dynamic), or wether we will treat all symbol files as already linked at the correct address (target.execution-mode = static). We can also specify if the inferior we are debugging is being debugged on a bare board (target.execution-os-type = none), or debugging an OS where we have a JTAG or other direct connection to the inferior stops the entire OS (target.execution-os-type = halted), or if we are debugging a program on something that has live debug services (target.execution-os-type = live). For the "target.execution-os-type = halted" mode, we will need to create ProcessHelper plug-ins that allow us to extract the process/thread and other OS information by reading/writing memory. This should allow LLDB to be used for a wide variety of debugging tasks and handle them all correctly. llvm-svn: 125815
