the case with 16-bit to 32-bit.
Any speed up moving from 16 to 32 bits was due to clock speed, not
the number of bits in the registers.
The so-called 64-bit is really not 64-bit. The registers are still
32-bit,
Sorry, thats wrong. The registers *ARE* 64 bit.
So what is the reasoning why the int are still 4 bytes instead of 8 bytes ?
Can anyone clarify ?
it appears without having gone through the arch-docs.
I thoroughly recommend you do.
