Arnold Schwaighofer 2ced33808e SCEVExpander: Try hard not to create derived induction variables in other loops ... During LSR of one loop we can run into a situation where we have to expand the start of a recurrence of a loop induction variable in this loop. This start value is a value derived of the induction variable of a preceeding loop. SCEV has cannonicalized this value to a different recurrence than the recurrence of the preceeding loop's induction variable (the type and/or step direction) has changed). When we come to instantiate this SCEV we created a second induction variable in this preceeding loop. This patch tries to base such derived induction variables of the preceeding loop's induction variable. This helps twolf on arm and seems to help scimark2 on x86. Reapply with a fix for the case of a value derived from a pointer. radar://15970709 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201496 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-16 15:49:50 +00:00
