[PATCH] D138560: [lld][LTO] Add assembly output to LTO save-temps

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I am unsure I am convinced with the motivation. Say you have two bitcode files a.o and b.o, can you just use `clang++ -fuse-ld=lld a.o b.o -Wl,--lto-emit-llvm`? This can be used with `-Wl,--save-temps` as well. The output is named in term of the `-o` output file name, instead of `*.s`, but the slight difference doesn't warrant adding significant more complexity to LTOBackend.cpp as this patch does.
