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...

RTFM, it's even indexed

if you decide to not support this, then make it clear in your documentation that €ASM only partially supports the Win64 ABI. 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 ...

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...

That sounds good but that isn't what I'm seeing. I'm confused so here is what I am seeing for WinApi macro for example: The source of your confusion is that there are two versions of macro WinAPI: 32bit in the library winapi.htm, and 64bit in winabi.htm https://euroassembler.eu/maclib/winabi.htm#Wi...

I treat the term amphibious as designed for two realms — air and water — such as amphibious vehicle or animal (frog, salamander), and amphibious functions as designed for both character realms — ANSI and WIDE. Do you think that metaphore is really bad?

Ad assignes, occurs 8 times, mea culpa.

I noticed that in all of the macros, that they only support Win32 and not Win64. Is this because €ASM is still new and that is a feature not yet available? Many libraries shipped with €ASM contain macros for 64bit mode, as declared in the column Width at https://euroassembler.eu/maclib/ 1) I don't ...

%DataExp used in the example for %SET2 https://euroassembler.eu/eadoc/index.htm#pcSET2 is an arbitrary chosen name of preprocessing variable, which is being assigned with %SET2, it is not a function/macro/directive. The only pseudoinstructions which begin with % are listed at https://euroassembler....

There are many enhancements which I would like to add sometimes to EuroAssembler (not necessarily in this order): More practical project examples and skeletons. Translation of Manual to the Czech and other languages. Output program format A.OUT, ELF, Linux executable. Linux version of EuroAssembler ...
