  "message": "Only use instructions as insert locations for SCEVExpander\n\nSCEVExpander, which we are using during code generation, only allows\ninstructions as insert locations, but breaks in case BasicBlock-\u003eend() iterators\nare passed to it due to it trying to obtain the basic block in which code should\nbe generated by calling Instruction-\u003egetParent(), which is not defined for\n-\u003eend() iterators.\n\nThis change adds an assert to Polly that ensures we only pass valid instructions\nto SCEVExpander and it fixes one case, where we used IRBuilder-\u003eSetInsertBlock()\nto set an -\u003eend() insert location which was later passed to SCEVExpander.\n\nIn general, Polly is always trying to build up the CFG first, before we actually\ninsert instructions into the CFG sceleton. As a result, each basic block should\nalready have at least one branch instruction before we start adding code. Hence,\nalways requiring the IRBuilder insert location to be set to a real instruction\nshould always be possible.\n\nThanks Utpal Bora \u003ccs14mtech11017@iith.ac.in\u003e for his help with test case\nreduction.\n\nThis is a backport from r243830 as it was committed on trunk.\n\ngit-svn-id: https://llvm.org/svn/llvm-project/polly/branches/release_37@246029 91177308-0d34-0410-b5e6-96231b3b80d8\n",
