uabelho added a comment. Hi @mibintc ,
I think I'm seeing some oddities with this patch (current trunk, 0054c46095 <https://reviews.llvm.org/rG0054c46095eea7a10b9af8f5006160023b95046d>). With clang -S -Xclang -emit-llvm bbi-42553.c -o - on the input float rintf(float x); #pragma STDC FENV_ACCESS ON void t() { (void)rintf(0.0f); } I get bbi-42553.c:2:14: warning: pragma STDC FENV_ACCESS ON is not supported, ignoring pragma [-Wunknown-pragmas] #pragma STDC FENV_ACCESS ON ^ ; ModuleID = 'bbi-42553.c' source_filename = "bbi-42553.c" target datalayout = "e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-f80:128-n8:16:32:64-S128" target triple = "x86_64-unknown-linux-gnu" ; Function Attrs: noinline nounwind optnone strictfp uwtable define dso_local void @t() #0 { entry: %0 = call float @llvm.experimental.constrained.rint.f32(float 0.000000e+00, metadata !"round.tonearest", metadata !"fpexcept.ignore") #2 ret void } and if I remove the pragma I instead get define dso_local void @t() #0 { entry: %0 = call float @llvm.rint.f32(float 0.000000e+00) ret void } Before this patch I got the call to llvm.rint.f32 in both cases.
