[LLVMdev] Debug metadata after simplifications
Hi all, In order to identify loops I'm using the DILexicalScope metadata attached to the loop latch, but with some combinations of optimisations that metadata seems to disappear. For example, when -simplifycfg removes a block because it only contains a branch, and -loop-simplify recreates that block because it turned out to be a back-edge of some loop, the metadata gets removed.
