[FPEnv][WIP] Verify non-mixing of strictfp instructions and regular FP instructions
Needs ReviewPublic

Authored by kpn on May 13 2021, 10:09 AM.



This patch, which should be applied on _top_ of D68233, adds checking for illegal mixing of strictfp and regular FP instructions. Because regular FP instructions lack the ordering constraints of strictfp the mixing of them in a single function is forbidden.

This is not ready to commit as it needs polish. It will also probably cause test failures that need to be addressed first. I'm opening this ticket now to facilitate finding those test failures.
