There is a demand for optimized alignment in code segment here.
It's a good idea, I hope in some of the next releases should €ASM use multibyte NOP automatically instead of series of 0x90 bytes as the alignment stuff.

...by the called function, and not the callee. It is not explicitly specified there, but both preceding and successive sentences concern the caller and not the callee. And here MS explicitly says both the integer register and the floating-point register will contain the float value in case the call...

The monospace button visible when a message is posted didn't keep spaces at the beginning of line. I created new button pre which should be more appropriate for posting code samples with indention. Testing monospace : Sample PROC PUSHAD ; some code with indentation. POPAD RET ENDP Sample and now the...

Terrabytes of spaghetti code are used every day worldwide, see https://github.com/dominictarr/your-web-app-is-bloated . Your implementation is undoubtedly shorter. BTW notice what Microsoft says ad float passing: For vararg or unprototyped functions, any floating point values must be duplicated in t...

That will not work. Most functions only pass one or two floats -- the rest will be GP. Example ... invoke fakeFunction, dword1, float2, qword3, double4 --> ____ movq xmm3,double4 ____ mov __ r8,qword3 ____ movq xmm1,float2 ____ mov __ ecx,dword1 If you expand my current implementation of WinAPI , i...
