Dan Gohman	df2896d609	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Dan Gohman	5f6f8101d5	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
Evan Cheng	276f9b02c5	Minor optimization: ... Look for situations like this: %reg1024<def> = MOV r1 %reg1025<def> = MOV r0 %reg1026<def> = ADD %reg1024, %reg1025 r0 = MOV %reg1026 Commute the ADD to hopefully eliminate an otherwise unavoidable copy. llvm-svn: 65752	2009-03-01 02:03:43 +00:00
