2009-10-11	simplify some run lines, convert a test to filecheck.	Chris Lattner
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83750 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11	Change tests from "opt %s" to "opt < %s" so that opt doesn't see the	Dan Gohman
	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
2009-09-08	Use opt -S instead of piping bitcode output through llvm-dis.	Dan Gohman

2009-09-08	Change these tests to feed the assembly files to opt directly, instead	Dan Gohman
	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
2008-11-27	Make jump threading substantially more powerful, in the following ways:	Chris Lattner
	1. Make it fold blocks separated by an unconditional branch. This enables jump threading to see a broader scope. 2. Make jump threading able to eliminate locally redundant loads when they feed the branch condition of a block. This frequently occurs due to reg2mem running. 3. Make jump threading able to eliminate partially redundant loads when they feed the branch condition of a block. This is common in code with lots of loads and stores like C++ code and 255.vortex. This implements thread-loads.ll and rdar://6402033. Per the fixme's, several pieces of this should be moved into Transforms/Utils. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60148 91177308-0d34-0410-b5e6-96231b3b80d8
