Kenneth Uildriks	90fedc6ef9	Make opt default to not adding a target data string and update tests that depend on target data to supply it within the test ... llvm-svn: 85900	2009-11-03 15:29:06 +00:00
Dan Gohman	1880092722	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	72a13d2476	Use opt -S instead of piping bitcode output through llvm-dis. ... llvm-svn: 81257	2009-09-08 22:34:10 +00:00
Dan Gohman	9737a63ed8	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	99b7b3f03b	Teach InstCombine's ComputeMaskedBits to handle pointer expressions ... in addition to integer expressions. Rewrite GetOrEnforceKnownAlignment as a ComputeMaskedBits problem, moving all of its special alignment knowledge to ComputeMaskedBits as low-zero-bits knowledge. Also, teach ComputeMaskedBits a few basic things about Mul and PHI instructions. This improves ComputeMaskedBits-based simplifications in a few cases, but more noticeably it significantly improves instcombine's alignment detection for loads, stores, and memory intrinsics. llvm-svn: 49492	2008-04-10 18:43:06 +00:00
