James Y Knight	8043d5a964	NFC: update clang tests to check ordering and alignment for atomicrmw/cmpxchg. The ability to specify alignment was recently added, and it's an important property which we should ensure is set as expected by Clang. (Especially before making further changes to Clang's code in this area.) But, because it's on the end of the lines, the existing tests all ignore it. Therefore, update all the tests to also verify the expected alignment for atomicrmw and cmpxchg. While I was in there, I also updated uses of 'load atomic' and 'store atomic', and added the memory ordering, where that was missing.	2021-02-11 17:35:09 -05:00

NFC: update clang tests to check ordering and alignment for atomicrmw/cmpxchg.

The ability to specify alignment was recently added, and it's an
important property which we should ensure is set as expected by
Clang. (Especially before making further changes to Clang's code in
this area.) But, because it's on the end of the lines, the existing
tests all ignore it.

Therefore, update all the tests to also verify the expected alignment
for atomicrmw and cmpxchg. While I was in there, I also updated uses
of 'load atomic' and 'store atomic', and added the memory ordering,
where that was missing.

Having some kind of weird kernel-assisted ABI for these when the

exception; OSs have been gradually opting in for years and the code
was getting silly.

So let LLVM decide whether it's possible/profitable to inline them by
