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.
I added an inline height as part of the lldb_private::StackID class, the class
that helps us uniquely identify stack frames. 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.
A quick example:
% cat main.cpp
% ./build/Debug/lldb test/stl/a.out
Current executable set to 'test/stl/a.out' (x86_64).
(lldb) breakpoint set --address 0x0000000100000d31
Breakpoint created: 1: address = 0x0000000100000d31, locations = 1
(lldb) r

Each inline frame contains only the variables that they contain and each inlined
stack frame is treated as a single entity.

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.
I added an inline height as part of the lldb_private::StackID class, the class
that helps us uniquely identify stack frames. 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.
A quick example:
% cat main.cpp
% ./build/Debug/lldb test/stl/a.out
Current executable set to 'test/stl/a.out' (x86_64).
(lldb) breakpoint set --address 0x0000000100000d31
Breakpoint created: 1: address = 0x0000000100000d31, locations = 1

Each inline frame contains only the variables that they contain and each inlined
stack frame is treated as a single entity.

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.

Add a first pass at a "stop hook" mechanism. This allows you to add commands that get run every time the debugger stops, whether due to a breakpoint, the end of a step, interrupt, etc. You can also specify in which context you want the stop hook to run, for instance only on a particular thread, or only in a particular shared library, function, file, line range within a file.
Still need to add "in methods of a class" to the specifiers, and the ability to write the stop hooks in the Scripting language as well as in the Command Language.

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

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;

// See if we can find the Module, if so stick it in the SymbolContext.

FileSpec module_file_spec(spec_string, false);

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;

Add a first pass at a "stop hook" mechanism. This allows you to add commands that get run every time the debugger stops, whether due to a breakpoint, the end of a step, interrupt, etc. You can also specify in which context you want the stop hook to run, for instance only on a particular thread, or only in a particular shared library, function, file, line range within a file.
Still need to add "in methods of a class" to the specifiers, and the ability to write the stop hooks in the Scripting language as well as in the Command Language.

Removed all of the "#ifndef SWIG" from the SB header files since we are using
interface (.i) files for each class.
Changed the FindFunction class from:
uint32_t
SBTarget::FindFunctions (const char *name,
uint32_t name_type_mask,
bool append,
lldb::SBSymbolContextList& sc_list)
uint32_t
SBModule::FindFunctions (const char *name,
uint32_t name_type_mask,
bool append,
lldb::SBSymbolContextList& sc_list)
To:
lldb::SBSymbolContextList
SBTarget::FindFunctions (const char *name,
uint32_t name_type_mask = lldb::eFunctionNameTypeAny);
lldb::SBSymbolContextList
SBModule::FindFunctions (const char *name,
uint32_t name_type_mask = lldb::eFunctionNameTypeAny);
This makes the API easier to use from python. Also added the ability to
append a SBSymbolContext or a SBSymbolContextList to a SBSymbolContextList.
Exposed properties for lldb.SBSymbolContextList in python:
lldb.SBSymbolContextList.modules => list() or all lldb.SBModule objects in the list
lldb.SBSymbolContextList.compile_units => list() or all lldb.SBCompileUnits objects in the list
lldb.SBSymbolContextList.functions => list() or all lldb.SBFunction objects in the list
lldb.SBSymbolContextList.blocks => list() or all lldb.SBBlock objects in the list
lldb.SBSymbolContextList.line_entries => list() or all lldb.SBLineEntry objects in the list
lldb.SBSymbolContextList.symbols => list() or all lldb.SBSymbol objects in the list
This allows a call to the SBTarget::FindFunctions(...) and SBModule::FindFunctions(...)
and then the result can be used to extract the desired information:
sc_list = lldb.target.FindFunctions("erase")
for function in sc_list.functions:
print function
for symbol in sc_list.symbols:
print symbol
Exposed properties for the lldb.SBSymbolContext objects in python:
lldb.SBSymbolContext.module => lldb.SBModule
lldb.SBSymbolContext.compile_unit => lldb.SBCompileUnit
lldb.SBSymbolContext.function => lldb.SBFunction
lldb.SBSymbolContext.block => lldb.SBBlock
lldb.SBSymbolContext.line_entry => lldb.SBLineEntry
lldb.SBSymbolContext.symbol => lldb.SBSymbol
Exposed properties for the lldb.SBBlock objects in python:
lldb.SBBlock.parent => lldb.SBBlock for the parent block that contains
lldb.SBBlock.sibling => lldb.SBBlock for the sibling block to the current block
lldb.SBBlock.first_child => lldb.SBBlock for the first child block to the current block
lldb.SBBlock.call_site => for inline functions, return a lldb.declaration object that gives the call site file, line and column
lldb.SBBlock.name => for inline functions this is the name of the inline function that this block represents
lldb.SBBlock.inlined_block => returns the inlined function block that contains this block (might return itself if the current block is an inlined block)
lldb.SBBlock.range[int] => access the address ranges for a block by index, a list() with start and end address is returned
lldb.SBBlock.ranges => an array or all address ranges for this block
lldb.SBBlock.num_ranges => the number of address ranges for this blcok
SBFunction objects can now get the SBType and the SBBlock that represents the
top scope of the function.
SBBlock objects can now get the variable list from the current block. The value
list returned allows varaibles to be viewed prior with no process if code
wants to check the variables in a function. There are two ways to get a variable
list from a SBBlock:
lldb::SBValueList
SBBlock::GetVariables (lldb::SBFrame& frame,
bool arguments,
bool locals,
bool statics,
lldb::DynamicValueType use_dynamic);
lldb::SBValueList
SBBlock::GetVariables (lldb::SBTarget& target,
bool arguments,
bool locals,
bool statics);
When a SBFrame is used, the values returned will be locked down to the frame
and the values will be evaluated in the context of that frame.
When a SBTarget is used, global an static variables can be viewed without a
running process.

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.

Added a new option to the "source list" command that allows us to see where
line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:
(lldb) source list -f test.c -l1 -c222 -b
1 #include <stdio.h>
2 #include <sys/fcntl.h>
3 #include <unistd.h>
4 int
5 sleep_loop (const int num_secs)
[2] 6 {
7 int i;
[1] 8 for (i=0; i<num_secs; ++i)
9 {
[1] 10 printf("%d of %i - sleep(1);\n", i, num_secs);
[1] 11 sleep(1);
12 }
13 return 0;
[1] 14 }
15
16 int
17 main (int argc, char const* argv[])
[1] 18 {
[1] 19 printf("Process: %i\n\n", getpid());
[1] 20 puts("Press any key to continue..."); getchar();
[1] 21 sleep_loop (20);
22 return 12;
[1] 23 }
Above we can see there are two breakpoints for line 6 and one breakpoint for
lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table
entries for them. This helps visualize the data provided in the debug
information without having to manually dump all line tables. It also includes
all inline breakpoint that may result for a given file which can also be very
handy to see.

Removed all of the "#ifndef SWIG" from the SB header files since we are using
interface (.i) files for each class.
Changed the FindFunction class from:
uint32_t
SBTarget::FindFunctions (const char *name,
uint32_t name_type_mask,
bool append,
lldb::SBSymbolContextList& sc_list)
uint32_t
SBModule::FindFunctions (const char *name,
uint32_t name_type_mask,
bool append,
lldb::SBSymbolContextList& sc_list)
To:
lldb::SBSymbolContextList
SBTarget::FindFunctions (const char *name,
uint32_t name_type_mask = lldb::eFunctionNameTypeAny);
lldb::SBSymbolContextList
SBModule::FindFunctions (const char *name,
uint32_t name_type_mask = lldb::eFunctionNameTypeAny);
This makes the API easier to use from python. Also added the ability to
append a SBSymbolContext or a SBSymbolContextList to a SBSymbolContextList.
Exposed properties for lldb.SBSymbolContextList in python:
lldb.SBSymbolContextList.modules => list() or all lldb.SBModule objects in the list
lldb.SBSymbolContextList.compile_units => list() or all lldb.SBCompileUnits objects in the list
lldb.SBSymbolContextList.functions => list() or all lldb.SBFunction objects in the list
lldb.SBSymbolContextList.blocks => list() or all lldb.SBBlock objects in the list
lldb.SBSymbolContextList.line_entries => list() or all lldb.SBLineEntry objects in the list
lldb.SBSymbolContextList.symbols => list() or all lldb.SBSymbol objects in the list
This allows a call to the SBTarget::FindFunctions(...) and SBModule::FindFunctions(...)
and then the result can be used to extract the desired information:
sc_list = lldb.target.FindFunctions("erase")
for function in sc_list.functions:
print function
for symbol in sc_list.symbols:
print symbol
Exposed properties for the lldb.SBSymbolContext objects in python:
lldb.SBSymbolContext.module => lldb.SBModule
lldb.SBSymbolContext.compile_unit => lldb.SBCompileUnit
lldb.SBSymbolContext.function => lldb.SBFunction
lldb.SBSymbolContext.block => lldb.SBBlock
lldb.SBSymbolContext.line_entry => lldb.SBLineEntry
lldb.SBSymbolContext.symbol => lldb.SBSymbol
Exposed properties for the lldb.SBBlock objects in python:
lldb.SBBlock.parent => lldb.SBBlock for the parent block that contains
lldb.SBBlock.sibling => lldb.SBBlock for the sibling block to the current block
lldb.SBBlock.first_child => lldb.SBBlock for the first child block to the current block
lldb.SBBlock.call_site => for inline functions, return a lldb.declaration object that gives the call site file, line and column
lldb.SBBlock.name => for inline functions this is the name of the inline function that this block represents
lldb.SBBlock.inlined_block => returns the inlined function block that contains this block (might return itself if the current block is an inlined block)
lldb.SBBlock.range[int] => access the address ranges for a block by index, a list() with start and end address is returned
lldb.SBBlock.ranges => an array or all address ranges for this block
lldb.SBBlock.num_ranges => the number of address ranges for this blcok
SBFunction objects can now get the SBType and the SBBlock that represents the
top scope of the function.
SBBlock objects can now get the variable list from the current block. The value
list returned allows varaibles to be viewed prior with no process if code
wants to check the variables in a function. There are two ways to get a variable
list from a SBBlock:
lldb::SBValueList
SBBlock::GetVariables (lldb::SBFrame& frame,
bool arguments,
bool locals,
bool statics,
lldb::DynamicValueType use_dynamic);
lldb::SBValueList
SBBlock::GetVariables (lldb::SBTarget& target,
bool arguments,
bool locals,
bool statics);
When a SBFrame is used, the values returned will be locked down to the frame
and the values will be evaluated in the context of that frame.
When a SBTarget is used, global an static variables can be viewed without a
running process.
