Bob Wilson	bf9b221c00	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96057 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-13 00:31:44 +00:00
Dan Gohman	36a0947820	Eliminate more uses of llvm-as and llvm-dis. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81290 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 23:54:48 +00:00
Dan Gohman	ae3a0be92e	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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8	2009-06-04 22:49:04 +00:00
Evan Cheng	f62ce370a4	Avoid putting a split past the end of the live range; always shrink wrap live interval in the barrier mbb. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58309 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-28 00:47:49 +00:00
