Bob Wilson	01abf8fc2f	Besides removing phi cycles that reduce to a single value, also remove dead ... phi cycles. Adjust a few tests to keep dead instructions from being optimized away. This (together with my previous change for phi cycles) fixes Apple radar 7627077. llvm-svn: 96057	2010-02-13 00:31:44 +00:00
Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +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
Evan Cheng	fab31680e1	Avoid putting a split past the end of the live range; always shrink wrap live interval in the barrier mbb. ... llvm-svn: 58309	2008-10-28 00:47:49 +00:00
