I wish we had a build check for those.
Or maybe a tool/script that would look at libraries/drivers, catch
_mmXXXXX intrinsics and warn if such a library/driver has no call to
corresponding runtime check.
That would save us from having to go to
https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html
...
Could someone from Intel work on this?
In any case, adjusted indent, fixed Fixes: tag, removed superfluous
parenthesis, and applied, thanks.
