I remember from my days when we did 8086 Assembly at college it was more performant to do:
for (int i = 6; i > -1; i--)
as there was a JNS operation that means Jump if No Sign. Using this meant that there was no memory lookup after each cycle to get the c...
Is the sizeof(some pointer) always equal to four?
...
@monjardin: IIRC, the 8086 was like that. There was a 16 bit address and a 4 bit segment register. I believe a normal "NEAR" pointer was 16 bits and a pointer declared as "FAR" was more, probably 24, though I'm not sure.

Are types like uint32, int32, uint64, int64 defined in any stdlib header?
... It was built to be able to perform 64-bit arithmetic, if only because the 8086 needed to be able to do 32-bit arithmetic.
