  Hi,
These patches came out of some gcc work. That is now dropped but these
seem something that could be useful still.

Thx,
-Vineet

Some caveats I should have covered already.

This is specifically for [1]

[1] https://gcc.gnu.org/pipermail/bpf/2026-March/000077.html

And for the patchset (all 3 patches), while the actual code changes were 
done by human (me), the testsuite fixes were actually generated by 
Claude. But I take full responsibility for anything that's amiss and 
will be willing to fix that.

Cheers,
-Vineet
