Bob Wilson	874886cd66	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	2012-08-03 23:29:17 +00:00
Dan Gohman	c8054d90fb	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81293	2009-09-09 00:09:15 +00:00
Dan Gohman	a5b9645c4b	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	2009-06-04 22:49:04 +00:00
