My best guess at the cause would be the forced unroll in: https://github.com/gcc-mirror/gcc/blob/819098dc71f2079aedc15a904ab5f17f0788d991/libstdc%2B%2B-v3/include/bits/stl_algobase.h#L2107 These finds works on small numbers of iterations (often just up to 4), so probably that forced unroll is not profitable. It may make sense to restore vfind with a comment on why it's there. https://github.com/llvm/llvm-project/pull/109412 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
