Just realized I missed the PR115382 tag in the patch... Regards Robin

[PATCH] vect: Merge loop mask and cond_op mask in fold-left, reduction.

Hi, currently we discard the cond-op mask when the loop is fully masked which causes wrong code in gcc.dg/vect/vect-cond-reduc-in-order-2-signed-zero.c when compiled with -O3 -march=cascadelake --param vect-partial-vector-usage=2. This patch ANDs both masks instead. Bootstrapped and regtested on
