General Development "For years, PC programmers used x86 assembly to write performance-critical code. However, 32-bit PCs are being replaced with 64-bit ones, and the underlying assembly code has changed. This white paper is an introduction to x64 assembly. No prior knowledge of x86 code is needed, although it makes the transition easier."

I see in the Intel article it says that sometimes modern compilers and optimizers make mistakes. I have sometimes experienced that but always wondered what I'd done wrong and looking at x86 code from a compiler is never much fun.

One bug I see a often is that release and debug code can be so different that one never works while the other does, until I stumble on the C code that caused it.
