atomics: add the --disable-cx16-atomics

Open ggouaillardet opened this issue 4 years ago • 4 comments

Do not try the -mcx16 flag if --disable-cx16-atomics is used, and prevent the generation of instructions that are not available on all x86 platforms (such as Celeron N4000).

Always try to run a simple test to make sure the selected atomic generate correct results.

Thanks Orion Poplawski for reporting this issue.
