ABI and PIC mode need to be confirmed with user first.

same for CFI

We got confirmation from users to use -mabi=ilp32f and -fpic . They said no to CFI.
We got confirmation on the -march and qemu flags to use (had to add vlen=128, elen=32) as well.

This variant needed changes to picolibc, for enabling csr for vectors. The builds works with picolibc update.

Thanks Sam and Jonathon for pushing the picolibc test change for zcmt/xqccmt.
This change-id issue took lot of time to resolve (). I hope the build succeeds here as well.

Aren't we trying to cherry-pick to 22.x, not 23.x? The current milestone is 22.x, I think.

Jonathon Penix (jonathonpenix) · 2026-07-16T18:28:04Z

Also not sure if the comments requesting the cherry-pick were deleted or what, but from the one email I saw with a comment + based on the errors above, it looks like /cherry-pick or /cherry-pick <branch> is what was tried--the expected syntax is /cherry-pick <sha> (where is the sha of the commit to cherry-pick and the target branch is given by the milestone)
