[PATCH] D116694: [RISCV] Add strictfp support for compares.

[Craig Topper via Phabricator via llvm-commits]

craig.topper updated this revision to Diff 397729.
craig.topper added a comment.

Preserve NoFPExcept flag when expanding the pseudo. Though maybe NoFPExcept gives permission to not save/restore FFLAGS?
Add an FEQ to the NonSignaling pseudo expansion to signal for SNANs.
