It said: ./gcc.dg/vect/vect-nest-cycle-3.c ==309158== Use of uninitialised value of size 8 ==309158== at 0x1170D0F: constant_for_folding (gimple-match-head.c:79) ==309158== by 0x1170D0F: gimple_simplify(tree_code, tree_node*, tree_node*, tree_node*, gimple**, tree_node* (*)(tree_node*)) (gimple-match-head.c:697) ==309158== by 0x9039AA: gimple_build(gimple**, unsigned int, tree_code, tree_node*, tree_node*, tree_node*) (gimple-fold.c:7654) ==309158== by 0xE47018: gimple_build (gimple-fold.h:83) This first seems to go wrong sometime between 20201023 and 20201107.
