Hey Stephen, Not sure if that would be helpful but when I was dealing (and still am tbh) with the same issue for CPython I used this blogspot from ARM as a reference point: https://developer.arm.com/community/arm-community-blogs/b/architectures-and-processors-blog/posts/enabling-pac-and-bti-on-aarch64 .
Here is my solution which we already have in Fedora/RHEL, but not yet merged upstream as I have to figure out the non-frame pointers builds https://github.com/python/cpython/pull/130864 On Wed, Feb 11, 2026 at 10:52 PM Stephen Gallagher <[email protected]> wrote: > While attempting to package libuv 1.52.0, I discovered via rpminspect > that a change[1] made since 1.51.0 has introduced some assembly that > leaves GCC unable to determine whether the resulting binaries are > BTI-safe.
