clang: Report CPU time used, use stdin/stdout to avoid temp files - #49
Merged
Conversation
Expose the total system plus userspace time used by clang, to allow users to monitor how much of their CPU use can be attributed to clang. Add a new CompileRes() API to avoid breaking existing users.
If the opts.Output directory isn't set, use stdin to pass the source to clang, and read the ELF from stdout. This avoids needing to write to temporary files.

This PR contains two changes to the
clangpackage:CompileRes()method that returns a struct (so we could extend it in the future) with the total CPU time used byclang.stdin/stdout, which is simpler (no need to create and clean up directories) and should be faster.
