Dan Gohman	9268d67079	Teach ScalarEvolution how to compute a tripcount for a loop with ... true or false as its exit condition. These are usually eliminated by SimplifyCFG, but the may be left around during a pass which wishes to preserve the CFG. llvm-svn: 96683	2010-02-19 18:12:07 +00:00
Dan Gohman	205b641954	Change tests from "opt %s" to "opt < %s" so that opt doesn't see the ... input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537	2009-09-11 18:01:28 +00:00
Dan Gohman	8d84372836	Change these tests to feed the assembly files to opt directly, instead ... of using llvm-as, now that opt supports this. llvm-svn: 81226	2009-09-08 16:50:01 +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
Dan Gohman	b36bd824fe	Rename IndVarsSimplify to IndVarSimplify, to be consistent with ... the name used in the code that these tests are for. llvm-svn: 64624	2009-02-16 00:56:15 +00:00
