[PATCH] D115850: [LTO][codegen] Add TargetLibraryInfoWrapperPass initially

[Freddy, Ye via Phabricator via llvm-commits]

FreddyYe added a comment.

CodeGenPasses is a legacy pass manager here. For now. `llc.cpp` has not switched to the new pass manager. `llc.cpp` does add this pass. And many passes in codegen need a right TargetLibraryInfo. If not adding it here with the module's triple info. TargetLibraryInfo will be initialized with a null string. That results in setting many library calls unavailable, as conservative as possible. I think it's not reasonable. Welcome discuss! Welcome adding more reviewers.
