files in this directory. If it should be defined anywhere, it should be defined when building lib/LTO/LTOCodeGenerator.cpp, but we've not had it defined there for quite some time, so that doesn't really seem to be very important. (It also would slow down the modules build by creating extra module variants.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218544 91177308-0d34-0410-b5e6-96231b3b80d8
