Bill Wendling	97b9359623	Do trivial CSE of dead BBs during codegen preparation. ... Some BBs can become dead after codegen preparation. If we delete them here, it could help enable tail-call optimizations later on. <rdar://problem/10256573> llvm-svn: 152002	2012-03-04 10:46:01 +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
Dan Gohman	3c7b9ba547	Re-enable SelectionDAG CSE for calls. It matters in the case of ... libcalls, as in this testcase on ARM. llvm-svn: 56226	2008-09-15 19:46:03 +00:00
