I'm not privy to any 'developer' info, but I believe it's been stated that tiger's 64-bitness is an LP model (i.e. Longs and Pointers are 64-bits) rather than an ILP (Ints, Longs and Pointers are 64-bit) model.

So that would make
1) yes
2) no, 8
3) not sure, probably yes
4) 8
5) both
6) don't know, we'll have to see. This is API and not compiler.

Hi,

I think this qualifies as borderline NDA territory, since gcc development is an open thing.

What kind of 64-bit support is there in Xcode 2.0 and Apple gcc 3.5? In particular:

1. Is sizeof(int) == 4?
2. Is sizeof(long) == 4?
3. Is sizeof(long long) == 8?
4. Is sizeof(void*) == 4 or 8? Or is there some kind of typedef and/or funky conversion for 32-bit vs. 64-bit pointer?
5. Is size_t same as unsigned long or unsigned long long?
6. Can we now malloc, vm_alloc, mmap more than 2G at a time i.e. will those low-level UNIXish API's allow a 64-bit parameter as a size?


Cheers, Glen Low
