We can't handle Pmode void* like other pointers?


mem_mode == VOIDmode doesn't mean a void* pointer, mem_mode != VOIDmode
means mem_loc_descriptor is called on some MEM's address and gives the
mode of the MEM, while VOIDmode mem_mode means it isn't a memory address,
but just a random rtl that we wish to translate into DWARF location
expression.

Ah, OK.
