[PATCH] D48131: [RISCV] Implement codegen for cmpxchg on RV32IA

[Alex Bradbury via Phabricator via llvm-commits]

asb updated this revision to Diff 169192.
asb retitled this revision from "[RISCV] Implement codegen for cmpxchg on RV32I" to "[RISCV] Implement codegen for cmpxchg on RV32IA".
asb added a comment.

Rebased patch. No changes, but I had to re-generate the new atomic-cmpxchg.ll lines as regalloc is slightly different after the recent enableMultipleCopyHints change.
