Adding -verify-machineinstrs option to PowerPC tests Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624 2016-08-04 02:17:35 +08:00			`; RUN: llc -verify-machineinstrs < %s -mattr=-vsx -march=ppc32 \| grep fnabs`

Refactor and check "onlyReadsMemory" before optimizing builtins. This patch is mostly just refactoring a bunch of copy-and-pasted code, but it also adds a check that the call instructions are readnone or readonly. That check was already present for sin, cos, sqrt, log2, and exp2 calls, but it was missing for the rest of the builtins being handled in this code. llvm-svn: 161282 2012-08-04 07:29:17 +08:00			`%Y = call double @fabs( double %X ) readnone ; <double> [#uses=1]`
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 06:49:04 +08:00			`%Z = fsub double -0.000000e+00, %Y ; <double> [#uses=1]`
