AutoCAD Crack + [Mac/Win]


Does the compiler perform any optimizations when a type is not using const?

I have a function to take in a long, store it in a long, then immediately return it. I’m wondering if there is any difference in the assembly code between these two:
long long foo(const int x) {
long long val = x;
return val;

and this:
long long foo(int x) {
long long val = x;
return val;

I.e. is there any difference in the code in between the two? Or is the compiler smart enough to optimize this away entirely?
To make the case for why I asked the question: the compiler can detect that a function isn’t going to modify any parameters, so it can skip the whole initialization process and just copy the parameter into the stack directly. The performance difference (if any) is therefore what I want to know.


Yes, the optimizer will perform these optimizations. It may also expand certain asm instructions into multiple ones, or inline one into multiple ones. And when optimization is enabled, no warning is emitted if the body of a function doesn’t do anything with the variables, or if the variables are declared as const.
It’s hard to tell what the compiler will actually do for you without any code. The compiler is allowed to do whatever it wants to, including loading/copying your variables into memory, depending on what it thinks will result in the most efficient code.
It’s not necessarily the case that your first example will be faster than your second, because the optimizer may decide to go ahead and use a register for val, and may make the register it uses a different one for each call to foo, and then the memory copy may be slower than a register copy (but maybe faster than a load and the eventual store). Or the optimizer may decide to do something more complicated than that, and may handle calling foo differently from other functions, etc.


If there is no const in the first function, a better compiler will have no reason to generate the code for the second one. In this case the second is a better match for the compiler.
The optimizer can remove the const declaration and still use the copy from the first function.
