That is incorrect code. The registers are never put on the shadow space stack by the caller, but always by the callee. Seems I remember someone telling me to RTFM, in this case it should be the Win64 ABI manual :) . This is one of the problems with the WinAPI macro in 64-bit mode. It is the functio...

I would like to suggest that for Win64 support in €ASM, could you provide a fastcall, cdecl, stdcall, and vector directive/macro for the calling convention, or at least make it possible so that a macro could be written by users to do this? I think any convention is already possible at macro level. ...

It is a very stupid thing to save parameters to a register, only to move them onto the stack. That wastes cycles and memory...Either save parameters to the registers (like a fastcall does) or move them to the stack (like cdecl does) but don't do both at the same time My 64-bit paint program has 86 ...

After the call is made to the function, per the Win64 ABI it must then copy rcx,rdx,r8, and r9 into the SHADOW SPACE at the start of that function. I didn't know that. Agner Fog in book 5, page 19, says ad 64 bit Windows: Since the shadow space is owned by the called function, it is safe to use the...

Actually it's not €ASM's job to support various ABI invokations (Win64, SystemV, Delphi etc), they are implemented as external macros, totally in the hands of €ASM users. So let's make them more compliant. Don't call the macro "WinAPI" then for 64-bit code, since that is a misnomer. Call ...

I tried, but you misspelled license so my search returned nothing .

Note to self: Remember, licence is a noun, license is a verb.

And invokation is spelled invocation.

I can't find the license for €ASM. What is the license?

RE: https://choosealicense.com/no-permission/

What if the operand is provided as an immediate number, e.g. Function 0x8040 , how should the poor assembler know whether it is integer number 32832 or real4 number 4.0? That is the purpose of having a PROTO in the vast majority of all other assemblers. Personally I don't like protos. They make the...

I am experienced, having written a few full fledged 64-bit programs like a Paint program written completely with GoAsm, so I'm very familiar with how it works and it works like this: invoke fnTest,p1,p2,p3,p4,p5,,,p10 push p10 ; Put operands on stack, begin with the last. . . . push p5 ; = any valu...
