--- Comment #7 from Keith Miller <keith_miller at apple.com> ---
>From skimming the change in question the most suspicious thing is that GPRInfo::metadataTableRegister was added to RegisterSetBuilder::wasmPinnedRegisters even though it's not actually a pinned register. I think it could just be added to `JSEntrypointInterpreterCallee::calleeSaveRegistersImpl` and maybe some other places.
