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 |
