uweigand opened PR #2988 from s390x-atomic-part1
to main
:
This adds full back-end support for the Fence, AtomicLoad
and AtomicStore operations, and partial support for the
AtomicCas and AtomicRmw operations.The missing pieces include sub-word operations, operations
on little-endian memory requiring byte-swapping, and some
of the subtypes of AtomicRmw -- everything that cannot be
implemented without a compare-and-swap loop. This will be
done in a follow-up patch.This patch already suffices to make the test suite green
again after a recent change that now requires atomic
operations when accessing the heap.<!--
