Kamil Rytarowski 4791532830 Install six.py conditionally
Summary:
The current version of LLDB installs six.py into global python library directory. This approach produces conflicts downstream with distribution's py-six copy.

Introduce new configure option LLDB_USE_SYSTEM_SIX (disabled by default). Once specified as TRUE, six.py won't be installed to Python's directory.

Add new option in finishSwigWrapperClasses.py, namely --useSystemSix.

Chris Bieneman cee3837eb8 [CMake] Add explicit dependencies to plugins
Summary:
This patch does two things. First it updates all the ABI plugins with accurate dependencies, and second it adds a tracking mechanism for add_lldb_library to denote plugin libraries, allowing us to build up a list of all the configured plugins.

This list of generated plugins will be used during generating liblldb so that we can link all the plugins into the library.

If this patch looks good I will update all the other plugins in subsequent patches.

Pavel Labath e5cfc67113 [cmake] Make lldb build with the android ndk toolchain file
Summary:
The NDK cmake toolchain file defines CMAKE_SYSTEM_NAME=Android, so switch the

After migrating the last bits of non-toolchainy bits out of the in-tree
toolchain, I intend to delete it.

Summary:
This replaces all the uses of the __ANDROID_NDK__ define with __ANDROID__. This
is a preparatory step to remove our custom android toolchain file and rely on
the standard android NDK one instead, which does not provide this define.
Instead I rely, on __ANDROID__, which is set by the compiler.

I haven't yet removed the cmake variable with the same name, as we will need to
do something completely different there -- NDK toolchain defines
CMAKE_SYSTEM_NAME to Android, while our current one pretends it's linux.

Adrian McCarthy 4ad5def9b0 Refactor LLDB's Windows process plugin (NFC)
The Windows process plugin was broken up into multiple pieces a while back in
order to share code between debugging live processes and minidumps
(postmortem) debugging. The minidump portion was replaced by a cross-platform
solution. This left the plugin split into a formerly "common" base classes and
the derived classes for live debugging. This extra layer made the code harder
to understand and work with.

This patch simplifies these class hierarchies by rolling the live debugging
concrete classes up to the base classes. Last week I posted my intent to make
this change to lldb-dev, and I didn't hear any objections.

This involved moving code and changing references to classes like
ProcessWindowsLive to ProcessWindows. It still builds for both 32- and 64-bit,
and the tests still pass on 32-bit. (Tests on 64-bit weren't passing before
this refactor for unrelated reasons.)

Adrian McCarthy 1ca677f4c4 Remove Windows-specific minidump plugin
With the cross-platform minidump plugin working, the Windows-specific one is no longer needed. This eliminates the unnecessary code.

This does not eliminate the Windows-specific tests, as they hit a few cases the general tests don't. (The Windows-specific tests are currently passing.) I'll look into a separate patch to make sure we're not doing too much duplicate testing.

After that I might do a little re-org in the Windows plugin, as there was some factoring there (Common & Live) that probably isn't necessary anymore.

Chris Bieneman b92cfe6804 Unify Darwin and Non-Darwin printing of version output
Summary:
This change unifies and simplifies the code paths between the Darwin and non-Darwin code to print the LLDB version information.

It also introduces a new variable in CMake LLDB_VERSION_STRING which can be used to specify custom version information. On Darwin this value is implicitly set based on the resource/LLDB-Info.plist file.

With the LLDB_VERSION_STRING variable set to lldb-360.99.0, the -version output is:

> ./bin/lldb -version
lldb version 4.0.0 (lldb-360.99.0)
  clang revision 286264
  llvm revision 286265

This behavior is unified across all target platforms.

Pavel Labath 01a955a341 [cmake] Make dependencies of lldb libraries private, take 2
Summary:
The dependencies of our libraries (only liblldb, really) we marked as public, which caused all
their dependencies to be repeated when linking any executables to them. This is a problem because
then all the .a files could end up being linked twice, once to liblldb and once
again to to the executable linking against liblldb (lldb, lldb-mi). As it turns out,
our build actually depends on this behavior:
- on windows, lldb does not have getopt, so it pulls it from inside liblldb, even
  though getopt is not a part of the exported interface of liblldb (maybe some of
  the bsd variants have this problem as well)
- lldb-mi uses llvm, which again is not exported by liblldb

This change does not actually fix these problems (that is going to be a hard
one), but it does make them explicit by moving this magic from add_lldb_library
to the places the executable targets are defined. That way, I can link the
additional .a files only on targets that really need it, and the other targets
can build cleanly and make sure we don't regress further. It also fixes the
LLVM_LINK_LLVM_DYLIB build on linux.

Chris Bieneman 7176862809 [CMake] Fixing a small hack in add_lldb_library
This code was adding an explicit dependency on libclang because lldb needs clang headers, changing this to instead depend on the clang tablegen targets means we don't have to depend on building the clang bits in libclang that lldb doesn't need.

Note this is still a bit of a hack because we're adding the dependency to all lldb libraries, instead of just the ones that need it.

Chris Bieneman d3199f5ed2 [CMake] Initial support for LLDB.framework
Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.

With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.

The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.

With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

Pavel Labath 0e947eb636 Add cmake option to choose whether to use the builtin demangler
Summary:
Previously the builting demangler was on for platforms that explicitly set a flag by modifying
Mangled.cpp (windows, freebsd). The Xcode build always used builtin demangler by passing a
compiler flag. This adds a cmake flag (defaulting to ON) to configure the demangling library used
at build time. The flag is only available on non-windows platforms as there the system demangler
is not present (in the form we're trying to use it, at least).
The impact of this change is:
- linux: switches to the builtin demangler
- freebsd, windows: NFC (I hope)
- netbsd: switches to the builtin demangler
- osx cmake build: switches to the builtin demangler (matching the XCode build)

The main motivation for this is the cross-platform case, where it should bring more consistency
by removing the dependency on the host demangler (which can be completely unrelated to the debug
target).

Summary:
Recent increase in the usage of std::weak_ptr has caused us to rediscover an issue in libstdc++

unusable without exceptions in the presence of multiple threads. It's virtualy impossible to work
around this issue without implementing our own shared_ptr/weak_ptr substitutes, which does not
seem like a good idea.

Therefore, I am adding a big CMake warning which warns you about this issue if you're attempting
a to do a build which is suceptible to this problem and suggests possible alternatives. Right
now, nothing spectacular will happen if you ignore this warning (all the crashes I have seen
occur during process shutdown), but there's no guarantee the situation will not change in the
future.

- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform

This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).

There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).

The implementation follows existing platforms in a mostly straightforward
manner.  A couple of things that are different:

- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
  since some registers (access register) reside at offsets in the user area
  that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
  accessing aligned 8-byte blocks in the user area.  Instead, we use a s390
  specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
  allows accessing a whole block of the user area in one go, so in effect
  allowing to treat parts of the user area as register sets.

- SystemZ hardware does not provide any means to implement read watchpoints,
  only write watchpoints.  In fact, we can only support a *single* write
  watchpoint (but this can span a range of arbitrary size).  In LLDB this
  means we support only a single watchpoint.  I've set all test cases that
  require read watchpoints (or multiple watchpoints) to expected failure
  on the platform.  [ Note that there were two test cases that install
  a read/write watchpoint even though they nowhere rely on the "read"
  property.  I've changed those to simply use plain write watchpoints. ]
