Wojciech Matyjewicz	de0f2382e4	Fix PR2088. Use modulo linear equation solver to compute loop iteration ... count. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53810 91177308-0d34-0410-b5e6-96231b3b80d8	2008-07-20 15:55:14 +00:00
Nick Lewycky	e637727bed	XFAIL this test. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53793 91177308-0d34-0410-b5e6-96231b3b80d8	2008-07-19 15:52:06 +00:00
Wojciech Matyjewicz	5c779a46b0	While testing particular algorithms to compute loop iteration count the brute ... force evaluation (ComputeIterationCountExhaustively) should be turned off. It doesn't apply to trip-count2.ll because this file tests the brute force evaluation. The test for PR2364 (2008-05-25-NegativeStepToZero.ll) currently fails showing that the patch for this bug doesn't work. I'll fix it in a few hours with a patch for PR2088. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53792 91177308-0d34-0410-b5e6-96231b3b80d8	2008-07-19 13:26:15 +00:00
Nick Lewycky	aadc6b68c7	Whoops -- forgot PR reference on this test. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51569 91177308-0d34-0410-b5e6-96231b3b80d8	2008-05-26 20:23:33 +00:00
Nick Lewycky	04b35e8532	Don't treat values as signed when looking at loop steppings in HowForToNonZero. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51560 91177308-0d34-0410-b5e6-96231b3b80d8	2008-05-25 23:43:32 +00:00
