From 67e1e7c3d84e04abbda81426827c72937e0aceba Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Tue, 20 Jan 2009 21:58:13 +0000 Subject: Calls to fmod, it turns out, are constant-folded by invoking the host fmod, not by lowering to frem and constant-folding that. Fix this so it tests what I want to test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62622 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/InstCombine/2009-01-19-fmod-constant-float.ll | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) (limited to 'test/Transforms/InstCombine/2009-01-19-fmod-constant-float.ll') diff --git a/test/Transforms/InstCombine/2009-01-19-fmod-constant-float.ll b/test/Transforms/InstCombine/2009-01-19-fmod-constant-float.ll index 7c63ff6924..9cdb425ab4 100644 --- a/test/Transforms/InstCombine/2009-01-19-fmod-constant-float.ll +++ b/test/Transforms/InstCombine/2009-01-19-fmod-constant-float.ll @@ -11,7 +11,7 @@ entry: %retval = alloca float ; [#uses=2] %0 = alloca float ; [#uses=2] %"alloca point" = bitcast i32 0 to i32 ; [#uses=0] - %1 = call double @fmod(double 1.000000e-01, double 1.000000e+00) nounwind readonly ; [#uses=1] + %1 = frem double 1.000000e-01, 1.000000e+00 ; [#uses=1] %2 = fptrunc double %1 to float ; [#uses=1] store float %2, float* %0, align 4 %3 = load float* %0, align 4 ; [#uses=1] @@ -23,14 +23,12 @@ return: ; preds = %entry ret float %retval1 } -declare double @fmod(double, double) nounwind readonly - define float @test2() nounwind { entry: %retval = alloca float ; [#uses=2] %0 = alloca float ; [#uses=2] %"alloca point" = bitcast i32 0 to i32 ; [#uses=0] - %1 = call double @fmod(double -1.000000e-01, double 1.000000e+00) nounwind readonly ; [#uses=1] + %1 = frem double -1.000000e-01, 1.000000e+00 ; [#uses=1] %2 = fptrunc double %1 to float ; [#uses=1] store float %2, float* %0, align 4 %3 = load float* %0, align 4 ; [#uses=1] @@ -47,7 +45,7 @@ entry: %retval = alloca float ; [#uses=2] %0 = alloca float ; [#uses=2] %"alloca point" = bitcast i32 0 to i32 ; [#uses=0] - %1 = call double @fmod(double 1.000000e-01, double -1.000000e+00) nounwind readonly ; [#uses=1] + %1 = frem double 1.000000e-01, -1.000000e+00 ; [#uses=1] %2 = fptrunc double %1 to float ; [#uses=1] store float %2, float* %0, align 4 %3 = load float* %0, align 4 ; [#uses=1] @@ -64,7 +62,7 @@ entry: %retval = alloca float ; [#uses=2] %0 = alloca float ; [#uses=2] %"alloca point" = bitcast i32 0 to i32 ; [#uses=0] - %1 = call double @fmod(double -1.000000e-01, double -1.000000e+00) nounwind readonly ; [#uses=1] + %1 = frem double -1.000000e-01, -1.000000e+00 ; [#uses=1] %2 = fptrunc double %1 to float ; [#uses=1] store float %2, float* %0, align 4 %3 = load float* %0, align 4 ; [#uses=1] -- cgit v1.2.3
