[PATCH] D115055: [Support] Use final filename for Caching buffer identifier

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

A manual test looks like this:

  % out/gn/bin/clang -c -flto=thin main.cc -g
  % out/gn/bin/clang -flto=thin main.o -fuse-ld=lld -Wl,-cache_path_lto,thinltocache
  % dsymutil a.out

Without this change, this prints:

  % dsymutil a.out
  warning: (x86_64) /Users/thakis/src/llvm-project/thinltocache/Thin-6c0491.tmp.o unable to open object file: No such file or directory
  warning: no debug symbols in executable (-arch x86_64)

With this change, it doesn't print that.
