LSR has gradually been improved to more aggressively reuse existing code, particularly existing phi cycles. This exposed problems with the SCEVExpander's sloppy treatment of its insertion point. I applied some rigor to the insertion point problem that will hopefully avoid an endless bug cycle in this area. Changes: - Always used properlyDominates to check safe code hoisting. - The insertion point provided to SCEV is now considered a lower bound. This is usually a block terminator or the use itself. Under no cirumstance may SCEVExpander insert below this point. - LSR is reponsible for finding a "canonical" insertion point across expansion of different expressions. - Robust logic to determine whether IV increments are in "expanded" form and/or can be safely hoisted above some insertion point. Fixes PR11783: SCEVExpander assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148535 91177308-0d34-0410-b5e6-96231b3b80d8 |
