commit r16-5626-g6828f063b59ddae8eef63529ae27224bdfbf1cbc Author: Richard Biener <[email protected]> Date: Wed Nov 26 12:49:58 2025 +0100 Fix loop masked inbranch SIMD clone codegen for AVX512 The following applies the earlier fix for conditional SIMD clone calls to the loop masked case. * tree-vect-stmts.cc (vectorizable_simd_clone_call): Handle AVX512 masking for loop masked SIMD clone call.
