Fix the folding of floating-point math library calls, like sin(infinity), so that it detects errors on platforms where libm doesn't set errno. It's still subject to host libm details though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114148 91177308-0d34-0410-b5e6-96231b3b80d8 2010-09-17 01:38:06 +00:00			`; RUN: opt -instcombine -S < %s \| FileCheck %s`
