mclow.lists added a comment. /me wonders what the perf difference when `_LIBCPP_UNROLL_LOOPS` is defined or not.
I think this (`_LIBCPP_UNROLL_LOOPS`) falls squarely into Chandler's request that we complain to him when the compiler generates sub-optimal code, instead of doing things like manually unrolling loops. https://reviews.llvm.org/D26991 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
