A GCC cross-compiler targeting OpenBSD 7.7.
This version uses the patchset from OpenBSD ports (which is currently based on GCC 11.2), plus some extra patches, and is also rebased on top of the latest GCC 15.
I also removed BSD-specific code from the host tools to allow it to be compiled on Linux and other non-BSD platforms.
All architectures that the lang/gcc/11 port supports are also supported here, but note that I mostly only tested the x86_64 architecture.
