--- Comment #42 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Richard Biener from comment #19) > Shorter testcase, compilable and to the point. We are not able to CSE > the b1 && ... && b8 sequence because we produce control-flow for it > during gimplification. > > void bar (short *array, > short b1, short b2, short b3, short b4, > short b5, short b6, short b7, short b8) > { > array[0] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8; > array[1] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8; > } This reduced testcase we optimize since GCC 12.
