Have there been any implementations of gcc for a 32 bit pointer system
where the registers are 64 bits long?
I was looking at AArch64 and wondering about whether it mightn't be
better for a 32 bit system than AArch32 if all the pointers were 32 bit,
and as far as the ABI is concerned half the

Yes, the new x32 ABI for x86_64, see

MIPS (N32 ABI, and if you want, also O64) is another example.

The PA2.0 chips
Thanks for that about the MIPS and PA. Gosh now I feel rather silly, I
remember doing something like this years and years ago in a company I
was in at the time with MIPS and PowerPC but it was roll our own rather
than gcc. Parameters were passed on stack at the size they were rather
than
