[PATCH] D80952: [FPEnv][Clang][Driver] Disable constrained floating point on targets lacking support.

[Kevin P. Neal via Phabricator via cfe-commits]

kpn updated this revision to Diff 276166.
kpn added a comment.

Add the -fexperimental-strict-floating-point flag to enable on hosts that are not marked as supporting strict FP yet. Add test and documentation.

Update tests to use the new flag. This eliminates the XFAIL lines and should keep the tests running like before.

Hopefully this will work for 11.
