Benjamin Kramer	1266d46d32	Don't bother with sprintf, just pass the Twine through. ... llvm-svn: 94684	2010-01-27 19:58:47 +00:00
David Greene	627f40a9f2	Change errs() to dbgs(). ... llvm-svn: 92600	2010-01-05 01:26:41 +00:00
Dan Gohman	18fa5686f6	Add Loop contains utility methods for testing whether a loop ... contains another loop, or an instruction. The loop form is substantially more efficient on large loops than the typical code it replaces. llvm-svn: 91654	2009-12-18 01:24:09 +00:00
Chris Lattner	46b5c642b9	remove a bunch of extraneous LLVMContext arguments ... from various APIs, addressing PR5325. llvm-svn: 86231	2009-11-06 04:27:31 +00:00
Dan Gohman	415c64ea3f	Teach LoopUnroll how to bail if LoopSimplify can't give it what it needs. ... llvm-svn: 86164	2009-11-05 19:44:06 +00:00
Dan Gohman	2d02ff8cbb	Revert r85667. LoopUnroll currently can't call utility functions which ... auto-update the DominatorTree because it doesn't keep the DominatorTree current while it works. llvm-svn: 85670	2009-10-31 17:33:01 +00:00
Dan Gohman	041e2dbad1	Merge the enhancements from LoopUnroll's FoldBlockIntoPredecessor into ... MergeBlockIntoPredecessor. This makes SimplifyCFG slightly more aggressive, and makes it unnecessary for LoopUnroll to have its own copy of this code. llvm-svn: 85667	2009-10-31 16:08:00 +00:00
Dan Gohman	fa8969f70e	Simplify this code. ... llvm-svn: 85662	2009-10-31 14:46:50 +00:00
Dan Gohman	f70e76c435	Rename UnrollLoop.cpp to LoopUnroll.cpp, and LoopUnroll.cpp to ... LoopUnrollPass.cpp, for consistency with other passes which are similarly split. llvm-svn: 85659	2009-10-31 14:37:31 +00:00
