相当于 Gnu Assembler 中 NASM 的“dd”

Question

I'm trying to translate dd from NASM (or MASM) to GAS.
I can't find it anywhere in the manual.

Answer 1

In NASM, the dd pseudo op defines a "double word" (eg 4 byte integer):

https://nasm.us/doc/nasmdoc3.html#section-3.2

; Example:
dd      0x12345678          ; 0x78 0x56 0x34 0x12

In Gas, the corresponding directive would typically be .long :

; example:
dimensions:
  .long 0, 0
