Is there documentation anywhere on the format being output via `--call-graph-section`? I get you're checking the MD5, but I'm also interested in if we're checking the output sufficiently. https://discourse.llvm.org/t/rfc-computing-storing-and-restoring-conservative-call-graphs-with-llvm/58446/3 linked to the original RFCs, and from what I can tell there is more in the proposed section than just the hashes.

The failing test seems like its failing to match on a register. probably using a match statement/substitution would help https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-string-substitution-blocks
