Dan Gohman	f2f6ce65b7	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-11 18:01:28 +00:00
Dan Gohman	3e054fe9ef	Use opt -S instead of piping bitcode output through llvm-dis. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81257 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 22:34:10 +00:00
Dan Gohman	b1e1e82c54	Change these tests to feed the assembly files to opt directly, instead ... of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 16:50:01 +00:00
Dan Gohman	453aa4fbf1	Generalize SCEVExpander::visitAddRecExpr's GEP persuit, and avoid ... sending SCEVUnknowns to expandAddToGEP. This avoids the need for expandAddToGEP to bend the rules and peek into SCEVUnknown expressions. Factor out the code for testing whether a SCEV can be factored by a constant for use in a GEP index. This allows it to handle SCEVAddRecExprs, by recursing. As a result, SCEVExpander can now put more things in GEP indices, so it emits fewer explicit mul instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72366 91177308-0d34-0410-b5e6-96231b3b80d8	2009-05-24 18:06:31 +00:00
