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.

WebI think that's about it. Maybe sqrt. I'm programming a two-dimensional RTS game, which I have largely working, but the unit movement when using floating-point math (doubles) has very small inaccuracies over time (10-30 minutes) across multiple machines, leading to desyncs. This is presently only between a 32-bit OS and a 64-bit OS. 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. –
WebDec 18, 2009 · In C99, the C header defines nan(), nanf(), and nanl() that return different representations of NaN (as a double, float, and int respectively), and infinity (if avaliable) could be returned by generating one with log(0) or something. There's no standard way to check for them, even in C99. The header ( is for … WebJan 20, 2012 · Core 2 and later CPUs have been designed for 64-bit operation from the ground up. Generally, even code written for a 64-bit platform uses 32-bit variables where values will fit in them. This isn't primarily because arithmetic is faster (on modern CPUs, it generally isn't) but because it uses less memory and memory bandwidth.

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.
