From eeba6e83175d7835f3648c30a44c2ca12116d40b Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Tue, 28 Aug 2012 07:36:46 +0000 Subject: The commutative flag is already correctly set within the multiclass. If we set it here, then a 'register-memory' version would wrongly get the commutative flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162741 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/2012-08-28-UnsafeMathCrash.ll | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 test/CodeGen/X86/2012-08-28-UnsafeMathCrash.ll (limited to 'test/CodeGen/X86/2012-08-28-UnsafeMathCrash.ll') diff --git a/test/CodeGen/X86/2012-08-28-UnsafeMathCrash.ll b/test/CodeGen/X86/2012-08-28-UnsafeMathCrash.ll new file mode 100644 index 0000000..6ebbb2e --- /dev/null +++ b/test/CodeGen/X86/2012-08-28-UnsafeMathCrash.ll @@ -0,0 +1,20 @@ +; RUN: llc < %s -enable-unsafe-fp-math +; +target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:128:128-n8:16:32-S128" +target triple = "i386-apple-macosx10.8.0" + +define i32 @foo(float %mean) nounwind readnone ssp align 2 { +entry: + %cmp = fcmp olt float %mean, -3.000000e+00 + %f.0 = select i1 %cmp, float -3.000000e+00, float %mean + %cmp2 = fcmp ult float %f.0, 3.000000e+00 + %f.1 = select i1 %cmp2, float %f.0, float 0x4007EB8520000000 + %add = fadd float %f.1, 3.000000e+00 + %div = fdiv float %add, 2.343750e-02 + %0 = fpext float %div to double + %conv = select i1 undef, double 2.550000e+02, double %0 + %add8 = fadd double %conv, 5.000000e-01 + %conv9 = fptosi double %add8 to i32 + %.conv9 = select i1 undef, i32 255, i32 %conv9 + ret i32 %.conv9 +} -- cgit v1.1
