How good is the C++Compiler?

The big Question? · 2000-05-05T10:22:14

Well I have been wondering a bit about, how good/optimized the C++Compiler is. If I write code like: a = 23 +7; Will the compiler optimize this code to: a = 30; Which is faster and always correct. Also when you write C++ code like: func() { UINT u1, u2, u3; // Do something. UINT u4, u5; } Is the compiler then allocating memory 2 places, or just in the begining of the function. Because if the memory gets allocated one place, there´s a bigger chance, that it will fit into the CPUs cache, which is faster. Hope somebody knows this, because I want fast code! But don´t we all?

The post above about using FINDTHIS... this works because he is setting the compiler to create a listing file... and he is searching in that. A listing file is basically an intermediate step in which the assembly is visible and so is the c++ code.
