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. Differential Revision: https://reviews.llvm.org/D31985 llvm-svn: 300160
