It is sometimes useful to have the C++ standard library linked into the
assembly when compiling clang, particularly when distributing a compiler
onto systems that don't have a copy of stdlibc++ or libc++ installed.
This functionality should work with either GCC or Clang as the host
compiler, though statically linking libc++ (as may be required for
licensing purposes) is only possible if the host compiler is Clang with
a copy of libc++ available.

Summary:
Back in January I changed the minimum toolchain version required to build clang
and LLVM: D57264. Since then we've release LLVM 8, following
[our process](http://llvm.org/docs/DeveloperPolicy.html#toolchain)
it's therefore now a good time to remove the soft-error and officially deprecate
older toolchains. I tried this out last Tursday night to see if any bots
complained, and I saw no complaints. I also manually audited bots and didn't see
any bot that should break, but their toolchain information is unreliable and
some bots are offline.
Once this patch stick we'll move to C++14 as we've
[already agreed](http://lists.llvm.org/pipermail/llvm-dev/2019-January/129452.html).

It's been in for more than 30 min and no bots have complained. Let's see if some
slow ones catch up. I'll do another manual pass on bots later (in case some that
were down are back up), and then turn this on permanently through a regular
review.
llvm-svn: 368253
It's pretty hard to find a reliable list of which bots use which compiler version... so I'm going to commit this change which allows us to mandate the compilers required for C++14. This bump is what we've already agreed to do, so I'll use the list of failures to figure out which bots need to bump their compiler version. I'll revert the change in a few minutes.
The last discussion of this is here: http://lists.llvm.org/pipermail/llvm-dev/2019-August/134360.html

Summary: If you are generating an object library that depends on table-gen generate sources, you need the object library to depend on the tablgen target. Currently llvm_add_library doesn't add dependencies for object libraries at all, which is clearly problematic.

This dependency was removed in r357486, which has lead to a stream of difficult to diagnose bugs.
Without this dependency, when building with `LLVM_OPTIMIZED_TABLEGEN=On` the native tablegen executible may not be rebuilt at all, and often won't get rebuilt before targets that use the tablegen headers. In the best case this results in a build-time failure, in the worst case it results in runtime failures.

There were two main problems:
* The 'nativecodegen' pseudo-component was unconditionally adding
${native_tgt}CodeGen even though it conditionally added ${native_tgt}Info and
${native_tgt}Desc. This has been fixed by making ${native_tgt}CodeGen
conditional too
* The 'all' pseudo-component was causing library names like LLVMLLVMDemangle as
the expansion was to a library name and not a component. There doesn't seem to
be a list of available components anywhere so this has been fixed by moving the
expansion of 'all' back where it was before. This manifested in different ways
on different builders but it was the same root cause
llvm-svn: 366622
Some targets are missing LLVMDemangle, one is adding the LLVM prefix twice, and two
are hitting the very error this patch fixes for my target. Reverting while I work
through the reports.
llvm-svn: 366615
I believe this to have been a latent bug as the same expansion checks for the
existence of ${native_tgt}Info and ${native_tgt}Desc and only adds them if
they were compiled but unconditionally adds ${native_tgt}CodeGen.
This should fix llvm-clang-x86_64-win-fast which builds ARM only on an X86 host and similar builders.
llvm-svn: 366612
Summary:
If you use pseudo-targets like AllTargetsCodeGens in LLVM_DYLIB_COMPONENTS
then a test will fail because `./bin/llvm-config --shared-mode` can't
handle these targets. We can fix this by expanding them before embedding
the string into llvm-config

lldb recently added a tablegen tool. In order to properly cross compile
lldb standalone there needs to be a mechanism to generate the native

Other platforms don't have the capability to perform llvm_codesign

Summary:
This is a follow up to D64032. Afterwards if building utils is disabled
and cross compilation is attempted, CMake will complain that adding
`install()` directives to targets with EXCLUDE_FROM_ALL set is "undefined".
Indeed, it appears depending on the CMake version and the selected
Generator, the install rule will error because the underlying target isn't
built. Fix that by not adding the install rule if building utils is not
requested. Note that this doesn't prevent building tblgen as a
dependency in not cross-build, even if building tools is disabled.

Summary:
CMake+Xcode doesn't seem to handle targets that only have object
sources. This patch works around that limitation by adding a dummy
soruce file to any library target that is generated by llvm_add_library
when object libraries are generated.
Object libraries are generated whenever llvm_add_library is passed more
than one library type, which is now the default case for clang static
libraries (which generate STATIC and OBJECT libraries).

Summary:
In cross mode, we build a separate NATIVE tblgen that runs on the
host and is used during the build. Separately, we have a flag that
disables building all executables in utils/. Of course generally,
this doesn't turn off tblgen, since we need that during the build.
In cross mode, however, that tblegen is useless since we never
actually use it. Furthermore, it can be actively problematic if the
cross toolchain doesn't like building executables for whatever reason.
And even if building executables works fine, we can at least save
compile time by omitting it from the target build. There's two changes
needed to make this happen:
- Stop creating a dependency from the native tool to the target tool.
No such dependency is required for a correct build, so I'm not entirely
sure why it was there in the first place.
- If utils were disabled on the CMake command line and we're in cross mode,
respect that by excluding it from the install target (using EXCLUDE_FROM_ALL).

As the default message mode (i.e. level) is NOTICE in CMake, more then necessary messages get printed to stderr. Some tools, noticably ccmake treat this as an error and require additional confirmation and re-running CMake's configuration step.
This commit specifies a mode (either STATUS or WARNING or FATAL_ERROR) instead of the default.

When cross-compiling LLVM to android from Windows (for LLVMSupport), we would
attempt to execute `config.guess` to determine the host triple since
`CMAKE_SYSTEM_NAME` is not Windows and `CMAKE_C_COMPILER` will be set to GNU or

executed on Windows. Simply log a warning instead. The user can specify the
value for this instead in those cases.

Summary:
It is useful to build with _XOPEN_SOURCE defined on AIX, enabling X/Open
and POSIX compatibility mode, to work around stray macros and other
bugs in the headers provided by the system and build compiler.
This patch adds the config to cmake to build with _XOPEN_SOURCE defined
on AIX with a few exceptions. Google Test internals require access to
platform specific thread info constructs on AIX so in that case we build
with _ALL_SOURCE defined instead. Libclang also uses header which needs
_ALL_SOURCE on AIX so we leave that as is as well.
We also add building on AIX with the large file API and doing CMake
header checks with X/OPEN definitions so the results are consistent with
the environment that will be present in the build.

Recommit of r361790 that was temporarily reverted in r361793 due to bot breakage.
Summary:
The following changes were required to fix these tests:
1) Change LLVM_ENABLE_PLUGINS to an option and move it to
llvm/CMakeLists.txt with an appropriate default -- which matches
the original default behavior.
2) Move the plugins directory from clang/test/Analysis
clang/lib/Analysis. It's not enough to add an exclude to the
lit.local.cfg file because add_lit_testsuites recurses the tree and
automatically adds the appropriate `check-` targets, which don't
make sense for the plugins because they aren't tests and don't
have `RUN` statements.
Here's a list of the `clang-check-anlysis*` targets with this
change:
```
$ ninja -t targets all| sed -n "s/.*\/\(check[^:]*\):.*/\1/p" | sort -u | grep clang-analysis

CMake always uses absolute file paths in the generated compiler
invocation which results in absolute file paths being embedded in debug

This change introduces the LLVM_USE_RELATIVE_PATHS_IN_DEBUG_INFO which uses

Summary:
Clangd's framework is assembled by copying binaries from the lib and bin directories into a bundle shape. This results in an invalid bundle code signature because the signature only applies to the binaries not the resources.
This patch adds two new options to `llvm_codesign` to enable re-signing the library and XPC service as bundles.
The `BUNDLE_PATH` option allow specifying an explicit path to codesign, which enables signing bundles which aren't generated using CMake's `FRAMEWORK` or `BUNDLE` target properties.
The `FORCE` option allows re-signing binaries that have already been signed. This is required for how clangd exposes the clangd library and tools as both XPC and non-XPC services using the same binary.
