My only concern is the test strategy. A test against a hand constructed notes section is not indicative of what the binaries in the wild, where the notes section was built by a compiler, would look like.

Well... I am following the implementation in https://github.com/eliben/pyelftools/blob/main/test/testfiles_for_readelf/note_gnu_property.S

Maybe we can have a C code test case after the entire CFI support being implemented on the toolchain side.

That was before my time :) Anyway, if you can get a C[++] compiler to emit the right notes section, I think that'd be better. This PR will be sitting for a while anyway.

As of binutils 2.44, no support for RISCV notes.

Yes, and I know that my colleague has not submitted that to upstream yet
