Hi, I notice the following description is different from how spu & m32c use it.
In internal manual: bool TARGET_ADDR_SPACE_SUBSET_P (addr space t superset, [Target Hook] addr space t subset) Define this to return whether the subset named address space is contained within the superset named address space. Pointers to a named address space that is a subset of another named address space will be converted automatically without a cast if used together in arithmetic operations. Pointers to a superset address space can be converted to pointers to a subset address space via explicit casts. In spu & m32c ports: m32c_addr_space_subset_p (addr_space_t subset, addr_space_t superset) spu_addr_space_subset_p (addr_space_t subset, addr_space_t superset) I believe the document is wrong. The first argument is subset and the second one is superset. Should I submit a patch? Cheers, Bingfeng Mei
