Sorry for a late comment, but the following might be helpful:

- If golang compiler lowers to LLVM IR, it should be possible to dump it and reduce it using llvm-reduce,
- If not, but the compiler can emit an assembly (with all DWARF sections), it might be possible to reduce it using creduce.
- Otherwise, we'd need to work on extending BOLT's asm-dump to also dump DWARF sections, and reduce the resulting assembly.

Also, the commit title is out of sync with diff's title. Please double-check the commit before the push, and sync from phabricator as necessary.
