Hello, Not ... necessarily. The mips/n32 abi is one example. Code runs in a 32-bit address space (so pointers, and sizeof(void *) are 32-bits), but with 64-bit registers and 64-bit operations available.
This is distinct from n64, which does have 64-bit pointers. /Mark On Dec 13, 2008, at 7:01 AM, Zoltan Varga wrote: > Hi, > > gssize is the size needed to hold a memory address, if the machine > has 64 bit registers, > this is 64 bits.
