------- Comment #9 from ebotcazou at gcc dot gnu dot org 2008-07-27 09:16 ------- This points to an immediate problem in vn_reference_op_compute_hash:
/* Compute the hash for a reference operand VRO1. */
static hashval_t
vn_reference_op_compute_hash (const vn_reference_op_t vro1)
{
return iterative_hash_expr (vro1->op0, vro1->opcode)
+ iterative_hash_expr (vro1->op1, vro1->opcode);
}
op2 is not hashed (whereas it is on the 4.3 branch).
