Dan Gohman	4a63fad976	Teach SimplifyCFG how to simplify indirectbr instructions. - Eliminate redundant successors. - Convert an indirectbr with one successor into a direct branch. Also, generalize SimplifyCFG to be able to be run on a function entry block. It knows quite a few simplifications which are applicable to the entry block, and it only needs a few checks to avoid trouble with the entry block. llvm-svn: 111060	2010-08-14 00:29:42 +00:00
Chris Lattner	f21a220bcd	Implement PR5795 by merging duplicated return blocks. This could go further by merging all returns in a function into a single one, but simplifycfg currently likes to duplicate the return (an unfortunate choice!) llvm-svn: 91890	2009-12-22 06:07:30 +00:00
Chris Lattner	2b297ed9ee	convert to filecheck llvm-svn: 91889	2009-12-22 06:04:26 +00:00
Chris Lattner	dd5d035302	if basic blocks are destroyed while there are just BlockAddress' hanging around, then zap them. This is analogous to dangling constantexprs hanging off functions. llvm-svn: 85627	2009-10-30 22:39:36 +00:00
Chris Lattner	e54242dc02	fix a bunch of spurious failures for people whose home directory is sabre. llvm-svn: 81528	2009-09-11 17:02:12 +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
Tanya Lattner	baa370b37a	Upgrade tests to not use llvm-upgrade. llvm-svn: 48483	2008-03-18 03:45:45 +00:00
Reid Spencer	83b3d82672	Regression is gone, don't try to find it on clean target. llvm-svn: 33296	2007-01-17 07:59:14 +00:00
