X64 inline asm

[deepzero]

For the inline assembler, keep in mind that it heavily "corrupts" the optimization of the surrounding C code (well, at least it always did for MSVC, donno about Intel, but would guess it's the same). When the compiler reaches the asm block, it's a "black box" for it... so it dumps all the register values into local variables, appends the assembler block... and then loads the register values back.

I am using the 32 bit version VS2008 and it doesnt do that. It just blindly drops the __asm inlinded code into the middle of the function. You are responsible for saving and restoring registers/stack/... I also coudltn observe any difference as to the optimizing of surrounded code. It`s true, the inlinde asm code is NOT AT ALL optimized, but the surrounding code is.

they did same with default values for methods in c# - no such thing there because 'it might confuse programmer'.

lol, really? Source?
