Andrew Trick 4d4bbaf997 Fix SCEVExpander: don't try to expand quadratic recurrences outside a loop. ... Partial fix for PR17459: wrong code at -O3 on x86_64-linux-gnu (affecting trunk and 3.3) When SCEV expands a recurrence outside of a loop it attempts to scale by the stride of the recurrence. Chained recurrences don't work that way. We could compute binomial coefficients, but would hve to guarantee that the chained AddRec's are in a perfectly reduced form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193438 91177308-0d34-0410-b5e6-96231b3b80d8		2013-10-25 21:35:56 +00:00
