[PATCH] D149119: [CMake] Use llvm-nm to extract symbols for staged LTO builds on Windows

[Simon Tatham via Phabricator via cfe-commits]

simon_tatham added a comment.

Do LLVM's current portability goals include the constraint that you can only build LLVM for a platform it can also target? If not, then there surely still needs to be //some// kind of escape hatch so that you can avoid needing `llvm-nm` to already support the object file format of the host platform.

I suppose you could say that in that unusual situation it's up to you to adapt `extract_symbols.py` so that it has some other way to get the answers.
