* Reapplying r256836 with a fix for MSVC 14 support.Aaron Ballman2016-01-251-0/+17
| | | | | | | | Enable more strict standards conformance in MSVC for rvalue casting and string literal type conversion to non-const types. Also enables generation of intrinsics for more functions. Patch by Alexander Riccio llvm-svn: 258687
* [cmake] Disable manifest generation when LLD is the linkerReid Kleckner2016-01-221-4/+8
| | | | | | | Running mt.exe to make the manifest is really slow. Disabling manifest generation doesn't seem to break anything. llvm-svn: 258581
* Strip local symbols when using externalized debug info.Owen Anderson2016-01-221-1/+1
| | | | | | | | | | | When we build LLVM with externalized debug info, all debugging and symbolication related data is extracted into dSYM files prior to stripping. As such, there is no need to preserve local symbols in LLVM binaries after dSYM creation. This shrinks libLLVM.dylib from 58MB to 55MB on my system. llvm-svn: 258566
* tools/llvm-config: improve shared library supportAndrew Wilkins2016-01-201-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is a re-commit of r257003, which was reverted, along with the fixes from http://reviews.llvm.org/D15986. r252532 added support for reporting the monolithic library when LLVM_BUILD_LLVM_DYLIB is used. This would only be done if the individual components were not found, and the dynamic library is found. This diff extends this as follows: - If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared library, even if all component libraries exist. - Two flags, --link-shared and --link-static are introduced to provide explicit guidance. If --link-shared is passed and the shared library does not exist, an error results. Additionally, changed the expected shared library names from (e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an installation (and then only in CMake builds I think?), and not in the build tree; this breaks usage of llvm-config during builds, e.g. by llvm-go.

* Reenable -Wexpansion-to-defined.Nico Weber2016-01-191-3/+0
| | | | | | | | | I think I fixed all instances of this in the codebase (r258202, 258200, 258190). Also, the suppression didn't have an effect on bots using make anyways, and it looks like many bots still use configure/make bots. llvm-svn: 258210

* [cmake] Fix add_version_info_from_vcs git svn version bug.Geoff Berry2016-01-191-17/+9
| | | | | | | | | | | | | | | | | | | | Summary: add_version_info_from_vcs was setting SVN_REVISION to the last fetched svn revision when using git svn instead of the svn revision corresponding to HEAD. This leads to conflicts with the definition of SVN_REVISION in SVNVersion.inc generated by GetSVN.cmake when HEAD is not the most recently fetched svn revision. Use 'git svn info' to determine SVN_REVISION when git svn is being used instead (as is done in GetSVN.cmake).

* [CMake] Need to install VersionFromVCS.cmake as part of LLVM's CMake modulesChris Bieneman2016-01-151-1/+0

* [CMake] Add support for populating LLVM_REPOSITORY from CMake.Chris Bieneman2016-01-141-0/+16
| | | | | | Autoconf does this in the GetRepositoryPath script, CMake's VersionFromVCS does grab the SVN_REVISION, but doesn't populate the repository URL. llvm-svn: 257826

* Make WinCOFFObjectWriter.cpp's timestamp writing not use ENABLE_TIMESTAMPSNico Weber2016-01-061-0/+30
| | | | | | | | | | | | | | | | | | | | | LLVM_ENABLE_TIMESTAMPS controls if timestamps are embedded into llvm's binaries. Turning it off is useful for deterministic builds. r246905 made it so that the define suddenly also controls if the binaries that the llvm binaries _create_ embed timestamps or not – but this shouldn't be a configure-time option. r256203/r256204 added a driver option to toggle this on and off, so this patch now passes this driver option in LLVM_ENABLE_TIMESTAMPS builds so that if LLVM_ENABLE_TIMESTAMPS is set, the build of LLVM is deterministic – but the built clang can still write timestamps into other executables when requested. This also allows removing some of the test machinery added in r292012 to work around this problem. See PR24740 for background. http://reviews.llvm.org/D15783 llvm-svn: 256958

* win: Pass /W4 in front of all the -wd flags.Nico Weber2015-12-231-1/+4
| | | | | | | | | | | This should fix many many -Wunused-parameter warnings in self-host builds on Windows after r255382. cl.exe doesn't care about the order of /W4 and /wd flags, but clang-cl currently does (just like -Wno-foo -Wall order matters for clang). We might want to change how clang-cl behaves in the future, but until then this change makes self-host builds much more silent. llvm-svn: 256315
* Revert r254592 (virtual dtor in SCEVPredicate).Andy Gibbs2015-12-171-10/+17
| | | | | | | | Clang has better diagnostics in this case. It is not necessary therefore to change the destructor to avoid what is effectively an invalid warning in gcc. Instead, better handle the warning flags given to the compiler. llvm-svn: 255905

* [CMake] Ignore externalizing debuginfo for unit testsChris Bieneman2015-12-081-3/+5
| | | | | | If you externalize debug info for unit tests the test runner finds the mach-o inside the dsym bundle and tries to execute it as a test. llvm-svn: 255056

| | | | | | | | false positives that Microsoft says will be fixed in Update 2. Until this produces reliable diagnostics, it is safe to disable the diagnostic -- the compiler is not doing anything different than it previously did aside from issuing the diagnostic. (Note, this silences at least one false positive in LLVM with FeatureBitset uses.) llvm-svn: 254915

* [CMake] Fix handling of passing through semi-colon separated lists.Chris Bieneman2015-11-201-1/+2

* [CMake] Support -fvisibility-inlines-hidden when LLVM_ENABLE_PIC=OffChris Bieneman2015-11-181-7/+6

* [CMake] Add support for building the llvm test-suite as part of an LLVM ↵Chris Bieneman2015-11-111-0/+194
| | | | | | | | | | | | | | | | | | | build using clang and lld Summary: This patch adds a new CMake module for working with ExternalProjects. This wrapper for ExternalProject supports using just-built tools and can hook up dependencies properly so that projects get cleared out. The example usage here is for the llvm test-suite. In this example, the test-suite is setup as dependent on clang and lld if they are in-tree. If the clang or lld binaries change the test-suite is re-configured, cleaned, and rebuilt. This cleanup and abstraction wrapping ExternalProject can be extended and applied to other runtime libraries like compiler-rt and libcxx.

* [cmake] move SONAME handling to llvm_add_libraryAndrew Wilkins2015-11-101-14/+19
| | | | | | | | | | | | | | | | | | | | Summary: Move handling of the SONAME option from add_llvm_library to llvm_add_library, so that it can be used in sub-projects. In particular, this makes it possible to have consistently named shared libraries for LLVM, Clang and LLDB. Also, base the SONAME and symlinks on the output name by extracting the OUTPUT_NAME property, rather than assuming it is the same as the target name.

Linux libraries follow the pattern lib${name}.${MAJOR}.${MINOR}.so so that ldconfig won't pick it up incorrectly. Darwin libraries are not versioned. Note: On linux the non-versioned symlink is generated at install-time not build time. I plan to fix that eventually, but I expect that is good enough for the purposes of fixing this bug.

* llvm-config: Add --has-rtti optionTom Stellard2015-11-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | Summary: This prints NO if LLVM was built with -fno-rtti or an equivalent flag and YES otherwise. The reasons to add -has-rtti rather than adding -fno-rtti to --cxxflags are: 1. Building LLVM with -fno-rtti does not always mean that client applications need this flag. 2. Some compilers have a different flag for disabling rtti, and the compiler being used to build LLVM may not be the compiler being used to build the application.
