Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Zachary Turner f343968f5d Delete Host/windows/win32.h
It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.

This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.

There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.

This patch depends on LLVM revision r278170.

Saleem Abdulrasool 16ff860469 remove use of Mutex in favour of std::{,recursive_}mutex
This is a pretty straightforward first pass over removing a number of uses of
Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there
are interfaces which take Mutex::Locker & to lock internal locks. This patch
cleans up most of the easy cases. The only non-trivial change is in
CommandObjectTarget.cpp where a Mutex::Locker was split into two.

Jim Ingham 583bbb1dd4 Change over the broadcaster/listener process to hold shared or weak pointers
to each other.  This should remove some infrequent teardown crashes when the
listener is not the debugger's listener.

Processes now need to take a ListenerSP, not a Listener&.

This required changing over the Process plugin class constructors to take a ListenerSP, instead
of a Listener&.   Other than that there should be no functional change.

Jason Molenda e92a74ce64 Add code to PlatformDarwin and HostInfoMacOSX so they return the
correct OS type when running on an apple tv or apple watch.
Also, in TargetList::CreateTargetInternal, check that a platform
is returned by GetPlatformForArchitecture fallback instead of 
adding it to the vector of platforms unconditionally; we can end up
crashing when we call a member function on it later.

Todd Fiala 7df337f85c ArchSpec: fix unintentional promotion of unspecified unknowns to specified unknowns
* ArchSpec::MergeFrom() would erroneously promote an unspecified
  unknown to a specified unknown when both the ArchSpec and the merged
  in ArchSpec were both unspecified unknowns. This no longer happens,
  which fixes issues with global module cache lookup in some
  situations.

* Added ArchSpec::DumpTriple(Stream&) that now properly prints
  unspecified unknowns as '*' and specified unknows as 'unknown'.
  This makes it trivial to tell the difference between the two.
  Converted printing code over ot using DumpTriple() rather than
  building from scratch.

* Fixed up a couple places that were not guaranteeing that an
  unspecified unknown was recorded as such.

Chaoren Lin 372e9067a7 Rename `FileSpec::IsRelativeToCurrentWorkingDirectory` to `IsRelative`.
Summary:
`IsRelativeToCurrentWorkingDirectory` was misleading, because relative paths
are sometimes appended to other directories, not just the cwd. Plus, the new
name is shorter. Also added `IsAbsolute` for completeness.

Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Robert Flack 8ec55a53a7 Don't change the selected platform when creating the dummy target.
A dummy target is used by TargetList::CreateTargetInternal to prime newly
created targets. the first time this is done it creates the dummy target. The
dummy target is created with the host platform (See
TargetList::CreateDummyTarget) which results in switching the selected platform
back to the host platform even when creating a target for a different platform.
This change avoids changing the selected platform while creating the dummy
target to prevent this side effect.

Test Plan:
./dotest.py $DOTEST_OPTS -t -p TestCreateAfterAttach.py
Tests using process attach (e.g. TestCreateAfterAttach.py, TestHelloWorld.py)
now run successfully mac -> linux.

Ted Woodward 869e0c1c59 Fix selecting the Platform in TargetList::CreateTargetInternal()
Summary:
TargetList::CreateTargetInternal() will only select the current Platform. A previous patch always sets platform_sp to the current Platform, so a check later to see if platform_sp was not defined always failed, and the current Platform was used. This patch removes that check, so if the current Platform is not compatible with the target architecture, CreateTargetInternal() will call Platform::GetPlatformForArchitecture() to select a compatible Platform.

Vince, remote linux tests (Ubuntu -> remote Ubuntu) pass the same with and without this patch.

Greg Clayton d26a1e5060 Fixed the failing test:
./dotest.py -A x86_64 -C clang -v -t  -f TestImageListMultiArchitecture.test_image_list_shows_multiple_architectures

The problem was that if the platform wasn't compatible with the current file in the "target create" command, it wasn't finding a platform that was like it used to.

Also, the currently selected platform was being used upload the file _before_ the target was created which was incorrect as "target create a.out" might switch platforms if its architecture doesn't match, so I moved the uploading to happen after the target was created so we use the right platform (the one in the target, not the selected one).

Greg Clayton ccd2a6d958 Changes in 226712 needed some fixing as a platform is almost always selected and even if platform options are specified when doing a "target create" they would get ignored if a platform was already selected.
The change was made so we could re-use a platform if one was already created instead of creating a new one, but it would fail in the above case. To fix this, if we have a selected platform, we verify that the platform matches the current platform before we try to re-use it. We do this by asking the OptionGroupPlatform if the platform matches. If so, it returns true and we don't create a new platform, else we do.

Jim Ingham 33df7cd345 Add the ability to set breakpoints with conditions, commands, etc,
in the "dummy-target".  The dummy target breakpoints prime all future
targets.  Breakpoints set before any target is created (e.g. breakpoints
in ~/.lldbinit) automatically get set in the dummy target.  You can also
list, add & delete breakpoints from the dummy target using the "-D" flag,
which is supported by most of the breakpoint commands.

This removes a long-standing wart in lldb...

Jim Ingham 893c932acf This is the first step of making lldb able to create target-specific things
(e.g. breakpoints, stop-hooks) before we have any targets - for instance in 
your ~/.lldbinit file.  These will then get copied over to any new targets 
that get created.  So far, you can only make stop-hooks.

Breakpoints will have to learn to move themselves from target to target for
us to get them from no-target to new-target.

We should also make a command & SB API way to prime this ur-target.

Greg Clayton 8012cadbf3 Fixed more fallout from running the test suite remotely on iOS devices.
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener. 
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:

    size_t
    Target::UnloadModuleSections (const ModuleList &module_list);

    size_t
    Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

- Fixed SymbolFileDWARFDebugMap to load .o files correctly by just specifying the architecture without the vendor and OS now that "<arch>-apple-ios" is not compatible with "<arch>-apple-macosx" so we can load .o files correctly for DWARF with debug map

std::string
Module::GetSpecificationDescription () const;

This returns the module as "/usr/lib/libfoo.dylib" for normal files (calls "std::string FileSpec::GetPath()" on m_file) but it also might include the object name in case the module is for a .o file in a BSD archive ("/usr/lib/libfoo.a(bar.o)"). Cleaned up necessary logging code to use it.

Greg Clayton f4d6de6a53 Added the ability to extract a ModuleSpecList (a new class) from an ObjectFile. This is designed to be used when you have an object file that contains one or more architectures (MacOSX universal (fat) files) and/or one or more objects (BSD archive (.a files)).
There is a new static ObjectFile function you can call:

size_t
ObjectFile::GetModuleSpecifications (const FileSpec &file,
                                     lldb::offset_t file_offset,
                                     ModuleSpecList &specs)

This will fill in "specs" which the details of all the module specs (file + arch + UUID (if there is one) + object name (for BSD archive objects eventually) + file offset to the object in question).

This helps us when a user specifies a file that contains a single architecture, and also helps us when we are given a debug symbol file (like a dSYM file on MacOSX) that contains one or more architectures and we need to be able to match it up to an existing Module that has no debug info.

More fixes to how we handle paths that are used to create a target.

This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

Greg Clayton 1f7460716b <rdar://problem/11757916>
Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". 
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

- useless instance names for processes, threads

Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

Greg Clayton b3a40ba812 Platforms can now auto-select themselves if you specify a full target triple when doing a "target create" command.
Each platform now knows if it can handle an architecture and a platform can be found using an architecture. Each platform can look at the arch, vendor and OS and know if it should be used or not.

Greg Clayton c859e2d524 Full core file support has been added for mach-o core files.
Tracking modules down when you have a UUID and a path has been improved.

DynamicLoaderDarwinKernel no longer parses mach-o load commands and it
now uses the memory based modules now that we can load modules from memory.

Added a target setting named "target.exec-search-paths" which can be used
to supply a list of directories to use when trying to look for executables.
This allows one or more directories to be used when searching for modules
that may not exist in the SDK/PDK. The target automatically adds the directory
for the main executable to this list so this should help us in tracking down
shared libraries and other binaries.
