I'd prefer that there be a flags field, akin to SYMBOL_REF_FLAGS. You're going to have to check this property quite often; I'd rather the data be cached somewhere easy to get at, rather than burried in some data structure 4 levels removed. The flags field of the mem could be initialized by a target function that receives the decl or type, as received by set_mem_attributes. > *What to do, if the reload pass copy the REG_EXPR to a > MEM_EXPR (set_mem_attrs_from_reg)? I would expect you to do nothing. r~
