Started to ICE with r14-7194-g6cb155a6cf314232248a12bdd395ed4151ae5a28 with
pr113374.c: In function ‘void decode(vector)’:
pr113374.c:7:6: error: PHI node with wrong VUSE on edge from BB 5
7 | void decode(struct vector vec) {

r14-7195-g411de96dbf2bdafc7a90ebbfc63e68afd6388d29 changes the ICE to
during GIMPLE pass: vect
pr113374.c: In function ‘void decode(vector)’:

and finally r14-7196-g99c0a540d6689ede068f9ba98af6f38c3cd71362 to
during GIMPLE pass: vect
pr113374.c: In function ‘void decode(vector)’:
