* Fix a bug in LoopStrengthReduce that caused it to emit IR withDan Gohman2008-05-152-3/+42
| | | | | | | | | | | | | | | | | | use-before-def. The problem comes up in code with multiple PHIs where one PHI is being rewritten in terms of the other, but the other needs to be casted first. LLVM rules requre the cast instruction to be inserted after any PHI instructions, but when instructions were inserted to replace the second PHI value with a function of the first, they were ended up going before the cast instruction. Avoid this problem by remembering the location of the cast instruction, when one is needed, and inserting the expansion of the new value after it. This fixes a bug that surfaced in 255.vortex on x86-64 when instcombine was removed from the middle of the loop optimization passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51169 91177308-0d34-0410-b5e6-96231b3b80d8
