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
Dale Johannesen	c1acc3f764	Reverse a loop that is counting up to a maximum to ... count down to 0 instead, under very restricted circumstances. Adjust 4 testcases in which this optimization fires. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71439 91177308-0d34-0410-b5e6-96231b3b80d8	2009-05-11 17:15:42 +00:00
Owen Anderson	d6db225800	Eliminate another use of -disable-correct-folding. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54356 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-05 18:03:01 +00:00
Owen Anderson	2b85dc3544	Update these tests to work by disabling the new correct CFG generation. This flag should ONLY be used to for tests like these. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54334 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-04 23:55:29 +00:00

Evan Cheng	cddbb83ea8	Do not fold reload into an instruction with multiple uses. It issues one extra load. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44467 91177308-0d34-0410-b5e6-96231b3b80d8	2007-11-30 21:23:43 +00:00
