Does gcc allow backends to have a say in how pointers are represented (bits beyond the address), what happens in conversions between pointer types, and what happens in conversions between pointers and uintptr_t?
The target in question has: - one pointer format and set of load/store instructions for pointers to int/long - another format and set of load/store instructions for pointers to char - pointers to short use a third format in general, but can use the int/long format IF you know which half of the word you're going to access What mechanisms, if any, are present in gcc to deal with this?
