Otherwise, the executables fail to run being unable to locate the libraries (unless the LLVM directory is explicitly added to LD_LIBRARY_PATH). The staging directories are not altered since they work for our development setup anyway, and installing into two directories would unnecessarily make the code more complex.

* [CMake] Support multi-target runtimes buildPetr Hosek2017-07-111-1/+9
| | | | | | | | | | | | | | | | | | | | | This changes adds support for building runtimes for multiple different targets using LLVM runtimes directory. The implementation follow the model used already by the builtins build which already supports this option. To specify the runtimes targets to be built, use the LLVM_RUNTIME_TARGETS variable, where the valuae is the list of targets to build runtimes for. To pass a per target variable to the runtimes build, you can set RUNTIMES_<target>_<variable> where <variable> will be passed to the runtimes build for <target>. Each runtime target (except for the default one) will be installed into lib/<target> subdirectory. Build targets will be suffixed with the target name.

| | | | | | | | | | | | | For the case when LLVM_OPTIMIZED_TABLEGEN is ON (enables LLVM_USE_HOST_TOOLS), we need both _TABLEGEN_TARGET and _TABLEGEN_EXE in the DEPENDS list to have .inc files rebuilt on a tablegen change, as cmake does not propagate file-level dependencies of custom targets. We could always have just one dependency on both the target and the file, but the 2 cases would produce cleaner cmake files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@305142 91177308-0d34-0410-b5e6-96231b3b80d8

* [cmake] Enable reverse iteration by default through build macroMandeep Singh Grang2017-06-061-0/+4
| | | | | | | | | | | | | | | | | | Summary: Reverse iteration can be turned on, by default, by setting -DLLVM_REVERSE_ITERATION:BOOL=ON during cmake. With this enabled, we can uncover lots of cases of non-determinism in codegen by simply running our tests (without any other change). We can then setup a buildbot which will have this turned on by default. Initially, a lot of unit tests will fail in this configuration. Once we start fixing non-determinism issues, we can gradually make this a blocker for patches.

* Add a linker script to version LLVM symbolsSylvestre Ledru2017-04-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch adds a very simple linker script to version the lib's symbols and thus trying to avoid crashes if an application loads two different LLVM versions (as long as they do not share data between them). Note that we deliberately *don't* make LLVM_5.0 depend on LLVM_4.0: they're incompatible and the whole point of this patch is to tell the linker that. Avoid unexpected crashes when two LLVM versions are used in the same process. Author: Rebecca N.

* Support: Add a VCSRevision.h header file.Peter Collingbourne2017-04-131-38/+46
| | | | | | | | | | | | | | | | | | | | | This is a magic header file supported by the build system that provides a single definition, LLVM_REVISION, containing an LLVM revision identifier, if available. This functionality previously lived in the LTO library, but I am moving it out to lib/Support because I want to also start using it in lib/Object to create the IR symbol table. This change also fixes a bug where LLVM_REVISION was never actually being used in lib/LTO because the macro HAS_LLVM_REVISION was never defined (it was misspelled as HAVE_SVN_VERSION_INC in lib/LTO/CMakeLists.txt, and was only being defined in a non-existent file Version.cpp). I also changed the code to use "git rev-parse --git-dir" to locate the .git directory, instead of looking for it in the LLVM source root directory, which makes this compatible with monorepos as well as git worktrees.

| | | | | | | | | | | | | | | | | CMake variable LLVM_DEFINITIONS collects preprocessor definitions provided for host compiler that builds llvm components. A function add_llvm_definitions was introduced in AddLLVMDefinitions.cmake to keep track of these definitions and was intended to be a replacement for CMake command add_definitions. Actually in many cases add_definitions is still used and the content of LLVM_DEFINITIONS is not actual now. On the other hand the current version of CMake allows getting set of definitions in a more convenient way. This fix implements evaluation of the variable by reading corresponding cmake property.

| | | | | | | | | | | | | | | | | | | | | | | Summary: clang-cl understands the GCC-style -W[no-]foo flags, and for the most part ignores MSVC -wd flags. So, let's pass the curated set of warning flags we use on Unix on Windows. We can also stop passing /W4 -wd*, which for the most part corresponds to -Wall -Wextra with a bunch of flags that we mostly ignore. I had to disable -Wnon-virtual-dtor on Windows, because it fires on every COM class ever. I filed PR32286 to fix this. So far I've only found two instances of -Wstring-conversion in the WinASan code, which I'll fix. Other than that we seem clean.

I am unable to determine what the svn revision returned by this command means. During my testing this command returned a revision from a month ago which was not the HEAD of any of my local branches. Also, this revision was never actually added to the version string due to a typo in the script. All it was used for was to reject the revision number returned by git svn find-rev HEAD when the revision numbers didn't match. - Populate GIT_COMMIT even when we detect a git repo without any svn information.

* enable building with LTO on Windows using clang-cl and lldBob Haarman2017-03-011-10/+27
| | | | | | | | | | | | | | | Summary: With clang-cl gaining support for link-time optimization, we can now enable builds using LTO when using clang-cl and lld on Windows. To do this, we must not pass the -flto flag to the linker; lld-link does not understand it, but will perform LTO automatically when it encounters bitcode files. We also don't pass /Brepro when using LTO - the compiler doesn't generate object files for LTO, so passing the flag would only result in a warning about it being unused.

* [Support] Provide linux/magic.h fallback for older kernelsMichal Gorny2017-02-221-0/+9
| | | | | | | | | | | | | | | | | | | | | The function for distinguishing local and remote files added in r295768 unconditionally uses linux/magic.h header to provide necessary filesystem magic numbers. However, in kernel headers predating 2.6.18 the magic numbers are spread throughout multiple include files. Furthermore, LLVM did not require kernel headers being installed so far. To increase the portability across different versions of Linux kernel and different Linux systems, add CMake header checks for linux/magic.h and -- if it is missing -- the linux/nfs_fs.h and linux/smb.h headers which contained the numbers previously. Furthermore, since the numbers are static and the feature does not seem critical enough to make LLVM require kernel headers at all, add fallback constants for the case when none of the necessary headers is available.
