Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290 2009-09-09 01:54:48 +02:00			`; RUN: llc < %s -enable-unsafe-fp-math -march=x86-64 \| \`
New test case. DAGCombiner should be able to fold -sin(-x) in -enable-unsafe-fp-math mode. llvm-svn: 37841 2007-07-02 17:43:20 +02:00			`; RUN: not egrep {addsd\|subsd\|xor}`

Split the Add, Sub, and Mul instruction opcodes into separate integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt llvm-svn: 72897 2009-06-05 00:49:04 +02:00			`%f = fsub double 0.0, %e`
Add readonly to some sin and cos calls; transformations being checked aren't valid without it. llvm-svn: 82786 2009-09-25 20:15:29 +02:00			`%g = call double @sin(double %f) readonly`
