I'm maintaining a LLVM-based distro, and with this patch merged, no more
backport is required to build loongarch64 packages.
Also had a quick glance at Alpine's aports, there're two extra patches
backported by Alpine,
1. Define fpu and simd context in signal.h[1][2]
2. Define structures for LSX and LASX vector registers in bits/user.h[3][4]
where 1 affects dotnet and 2 affects binutils-gdb, according to the
commit messages.
Those're all patches which I'm aware of. I'm not sure whether the links
point to the latest revisions (the openwall archive is a little hard to
search).
Anyway, thanks for your great work!
