Ok maybe, at least in a first keeping the current pass order and disabling outliner when LOB is turned on is the thing to do, and we can move to more optimized version later. > Yes, but LowOverheadLoops does not increase block size or change the CFG.

Even if you only decrease the size you can have a distance increase due to aligment constraints, for instance if LOB removes some instructions before a load of a constant, then we have .align directive before a constant island, the load is moved upward and the distance between the load and the constant has increased Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D57054/new/ https://reviews.llvm.org/D57054 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
