Mehdi Amini 96b6ab7056 Add a flag to the LLVMContext to disable name for Value other than GlobalValue ... Summary: This is intended to be a performance flag, on the same level as clang cc1 option "--disable-free". LLVM will never initialize it by default, it will be up to the client creating the LLVMContext to request this behavior. Clang will do it by default in Release build (just like --disable-free). "opt" and "llc" can opt-in using -disable-named-value command line option. When performing LTO on llvm-tblgen, the initial merging of IR peaks at 92MB without this patch, and 86MB after this patch,setNameImpl() drops from 6.5MB to 0.5MB. The total link time goes from ~29.5s to ~27.8s. Compared to a compile-time flag (like the IRBuilder one), it performs very close. I profiled on SROA and obtain these results: 420ms with IRBuilder that preserve name 372ms with IRBuilder that strip name 375ms with IRBuilder that preserve name, and a runtime flag to strip Reviewers: chandlerc, dexonsmith, bogner Subscribers: joker.eph, llvm-commits Differential Revision: http://reviews.llvm.org/D17946 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 263086		2016-03-10 01:28:54 +00:00
