https://reviews.llvm.org/D32172 — looks like this was planned back in 2017 but the whole ASan thing ended up abandoned for some reason.. :(

My build of ASan that uses this field works, but what specifically should I test with the sanitizers that would depend on this register thing??

Repository

rS FreeBSD src repository - subversion

sys/arm64/include/ucontext.h
42	This conflicts with https://reviews.freebsd.org/D38983 , and certainly will break ABI. I'm not expert on arm64. Maybe new registers should contract with `struct arm64_reg_context` ? See https://reviews.freebsd.org/D43302 .
