Dmitri Gribenko	b137c9e551	Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID ... This is done to avoid odd test failures, like the one fixed in r171243. llvm-svn: 171246	2012-12-30 01:28:40 +00:00
Daniel Dunbar	b9ea94c990	Eliminate uses of %prcontext. ... - I'd appreciate it if someone else eyeballs my changes to make sure I captured the intent of the test. llvm-svn: 81083	2009-09-05 11:35:16 +00:00
Dan Gohman	426901aa19	Teach SCEVExpander's visitAddRecExpr to reuse an existing canonical ... induction variable when the addrec to be expanded does not require a wider type. This eliminates the need for IndVarSimplify to micro-manage SCEV expansions, because SCEVExpander now automatically expands them in the form that IndVarSimplify considers to be canonical. (LSR still micro-manages its SCEV expansions, because it's optimizing for the target, rather than for other optimizations.) Also, this uses the new getAnyExtendExpr, which has more clever expression simplification logic than the IndVarSimplify code it replaces, and this cleans up some ugly expansions in code such as the included masked-iv.ll testcase. llvm-svn: 73294	2009-06-13 16:25:49 +00:00
Dan Gohman	2625f2cb80	Make this testcase slightly less trivial, so that it doesn't fail ... if indvars happens to optimize away the unused primary induction variable. llvm-svn: 70333	2009-04-28 22:03:26 +00:00
Dan Gohman	73f794af6a	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
