WebJun 6, 2024 · C and C++ use 32 bit int because otherwise there is no 32 bit type available (char = 8 bit, short = 16 bit or you have no 16 bit type, int must be 32 bit or you have no 32 bit type). Swift on 64 bit devices has Int = 64 bit, but also has Int8, Int16, Int32 and Int64 so the problem that C has is avoided. – WebFeb 11, 2024 · 1. The compiler could generate the necessary 32 bit instructions to do 128 bit math on a 32 bit H/W architecture. But, they chose not to. To use 32 bit instructions -> 64 bit math or 64 bit insts -> 128 bit math, consider a multiply: For 32 -> 64, it takes 3 multiplies and two adds. About the same for 64 -> 128.

Web$ diff mult.s bit.s 24c24 > shll $2, %eax --- < sarl $2, %eax Here the compiler was able to identify that the math could be done with a shift, however instead of a logical shift it does a arithmetic shift. The difference between these would be obvious if we ran these - sarl preserves the sign. So that -2 * 4 = -8 while the shll does not.
