[PATCH] D141187: [SystemZ] Set setMaxAtomicSizeInBitsSupported

[Thorsten via Phabricator via llvm-commits]

tschuett added a comment.

No, yo don't. You cannot mix  lock-free and mutex atomics. E.g, if loads are lock-free and stores use a mutex. Then you have lost atomicity. Your mutex version could do stores one byte at a time.
