[PATCH] D130907: [Clang] Use pragma FENV_ROUND to reset rounding mode settings.

[Eli Friedman via Phabricator via cfe-commits]

efriedma added inline comments.


================
Comment at: clang/lib/Sema/SemaStmt.cpp:398
+    // If dynamic rounding mode is specified in absence of FENV_ACCESS, treat it
+    // as setting default rounding mode.
+    FpPragmaStack.CurrentValue.clearConstRoundingModeOverride();
----------------
I'm not really happy with the way this is written... like I mentioned in the other patch, keep the state transitions simple, and put the logic into the code that computes the derived properties.
