Chris Lattner	3fc3148b85	When unswitching a trivial loop, do admit we are doing it! :) ... llvm-svn: 26102	2006-02-10 01:36:35 +00:00
Chris Lattner	ed7a67b0de	Implement unconditional unswitching of 'trivial' loops, those loops that contain ... branches in their entry block that control whether or not the loop is a noop or not. llvm-svn: 26101	2006-02-10 01:24:09 +00:00
Chris Lattner	4f0e66df6a	Simplify control flow a bit, note that unswitch preserves canonical loop form ... llvm-svn: 26098	2006-02-09 22:15:42 +00:00
Chris Lattner	8976219850	Make the threshold a parameter ... llvm-svn: 26093	2006-02-09 20:15:48 +00:00
Chris Lattner	2826e0511b	Simplify the loop-unswitch pass, by not even trying to unswitch loops with ... uses of loop values outside the loop. We need loop-closed SSA form to do this right, or to use SSA rewriting if we really care. llvm-svn: 26089	2006-02-09 19:14:52 +00:00
Chris Lattner	c597b8a55e	Make iostream #inclusion explicit ... llvm-svn: 25514	2006-01-22 23:32:06 +00:00
Misha Brukman	b1c9317bb4	Remove trailing whitespace ... llvm-svn: 21427	2005-04-21 23:48:37 +00:00
Jeff Cohen	eca0d0f2da	Put createLoopUnswitchPass() into proper namespace ... llvm-svn: 19306	2005-01-06 05:47:18 +00:00
Alkis Evlogimenos	a5c04ee50f	Fixes to make LLVM compile with vc7.1. ... Patch contributed by Paolo Invernizzi! llvm-svn: 16152	2004-09-03 18:19:51 +00:00
Reid Spencer	7c16caa336	Changes For Bug 352 ... Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. llvm-svn: 16137	2004-09-01 22:55:40 +00:00
Chris Lattner	f48f777d4c	Initial checkin of a simple loop unswitching pass. It still needs work, ... but it's a start, and seems to do it's basic job. llvm-svn: 13068	2004-04-19 18:07:02 +00:00
