Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target| |x86_64-*-* Keywords| |missed-optimization --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Both with and without -fopenmp-simd works on aarch64-linux-gnu which has a reduction addition. Just looks like how reduction addition is handled for x86_64 really. Also we have: MEM <vector(4) short int> [(short int *)&D.2916] = vect__21.35_111; MEM <vector(4) short int> [(short int *)&D.2916 + 8B] = vect__21.35_112; vect__24.24_88 = MEM <vector(8) short int> [(short int *)&D.2916];
