From: Dale Johannesen Date: Tue, 20 Jan 2009 21:58:13 +0000 (+0000) Subject: Calls to fmod, it turns out, are constant-folded by X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=67e1e7c3d84e04abbda81426827c72937e0aceba;p=oota-llvm.git 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 --- 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 7c63ff69246..9cdb425ab49 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]
