syntax - Inlcude, conditional and macros

[Borneq]

In ml.exe is include 7zAsm.asm, which syntax is in Nasm?
How conditional,
ifdef x64
else
endif

How write macro
CRC macro op:req, dest:req, src:req, t:req
    op      dest, DWORD PTR [r5 + src * 4 + 0400h * t]
endm

Is any compatibility options in Nasm to Macro Assembler ?

[Frank Kotler]

Not much compatibility with Masm - t'wasn't a design consideration.

You can use "%ifdef", "%else", "%endif"... There's an extensive section in the Friendly Manual...

I'm not sure what your "CRC" macro is intended to emit. Can you show an example of its use? Perhaps we can figure out a Nasm equivalent...

Best,
Frank

    op      dest, DWORD PTR [r5 + src * 4 + 0400h * t]
endm

I believe this would be an adequate equivalent:

Code: [Select]

%macro CRC 4
    %1  %2, DWORD[r5 + %3 * 4 + 0400h * %4]
%endmacro
