Dmitri Gribenko	56bf2e1830	Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID ... This is done to avoid odd test failures, like the one fixed in r171243. llvm-svn: 171250	2012-12-30 02:33:22 +00:00
Bill Wendling	5858b56ce3	Ignore unreachable blocks when doing memory dependence analysis on non-local ... loads. It's not really profitable and may result in GVN going into an infinite loop when it hits constructs like this: %x = gep %some.type %x, ... Found via an LTO build of LLVM. llvm-svn: 166490	2012-10-23 18:37:11 +00:00
Chris Lattner	f0d59072de	fix PR9841 by having GVN not process dead loads. This was ... causing it to get into infinite loops when it would widen a load (which can necessarily leave around dead loads). llvm-svn: 131847	2011-05-22 07:03:34 +00:00
Chris Lattner	f492ece81e	a testcase that doesn't crash GVN but could someday. ... llvm-svn: 95851	2010-02-11 05:08:05 +00:00
Chris Lattner	8f77035568	merge crash-2.ll into crash.ll ... llvm-svn: 90969	2009-12-09 17:17:26 +00:00
Chris Lattner	367b5eafb7	minimize this a bit more. ... llvm-svn: 90216	2009-12-01 07:30:01 +00:00
Chris Lattner	fd75b90d81	merge 2009-11-29-ReverseMap.ll into crash.ll ... llvm-svn: 90212	2009-12-01 06:22:10 +00:00
Chris Lattner	cf0b198827	disable value insertion for now, I need to figure out how ... to inform GVN about the newly inserted values. This fixes PR5631. llvm-svn: 90022	2009-11-27 22:50:07 +00:00
