[libcxx-commits] [PATCH] D145716: [CMake] Unify llvm_check_linker_flag and llvm_check_compiler_linker_flag

[Martin Storsjö via Phabricator via libcxx-commits]

mstorsjo added a comment.

Btw, for issues like these, it would be super useful if there was a CI configuration that builds libcxx/libunwind/libcxxabi from scratch in an environment where there's no preexisting unwinder or C++ library.

I considered adding such a config for the mingw builds, by having the CI run script remove `lib{c++,unwind}.*` and the C++ headers from the toolchain before doing the regular CI build - but that doesn't work, since the CI environment doesn't start up from a clean container image every time, but runs persistently within a container, so any modifications to the toolchain within a CI job does carry over to later jobs too.
