Summary

Recognizing 'PT_OPENBSD_MUTABLE' segment type.

LGTM.

The feature may look weird, see (https://lobste.rs/s/wck0g4/openbsd_immutable_userland_mappings) :)

I am nervous with new OpenBSD specific program headers... Wish there won't be too many. Particularly, I wonder whether this new feature is a security theatre.

[brad]

I was wondering why llvm-readobj/ELF/program-headers.test was failing. I noticed the offsets had changed.
