[libc-commits] [PATCH] D152280: [libc] Add platform independent floating point rounding mode checks.

[Michael Jones via Phabricator via libc-commits]

michaelrj added inline comments.


================
Comment at: libc/src/__support/FPUtil/FEnvImpl.h:130
+// Quick free standing get rounding mode based on the above observations.
+LIBC_INLINE int quick_get_round() {
+  static volatile float x = 0x1.0p-24f;
----------------
I like the idea, but I'd like to have a flag to use the old method as well for targets where we're using `-ffastmath` or other optimizations that might precompute this value unexpectedly.
