From 1ea502b3c158159aa2d7827acbd81c7930165a13 Mon Sep 17 00:00:00 2001 From: Eli Friedman Date: Tue, 17 Jul 2018 20:28:31 +0000 Subject: [PATCH] [LangRef] Clarify which fast-math flags affect fcmp. nsz has no effect due to the way fcmp is defined; +0 and -0 compare equal anyway. reassoc could have the obvious effect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@337322 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/LangRef.rst | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/docs/LangRef.rst b/docs/LangRef.rst index 9c10bbb0d61..1f4641cb231 100644 --- a/docs/LangRef.rst +++ b/docs/LangRef.rst @@ -9294,7 +9294,7 @@ otherwise unsafe floating-point optimizations.
