ScalarEvolution doesn't allow the operands of an AddRec to be variant in the loop of the AddRec. When we rewrite parameter SCEVs it might seem like the new SCEV violates this property and ScalarEvolution will trigger an assertion. To avoid this we move the start part out of an AddRec when we rewrite it, thus avoid the operands to be possibly variant completely. llvm-svn: 251945 |
