assembly - NASM TO GAS: counterpart of resw in GAS

Question

I am tasked to convert my assembly program which uses NASM to GAS. Unfortunately there are lots of mismatched statements. I have converted some of them but I am still having trouble on how to convert this statement

min resw 1

Answer 1

You could try:

.lcomm min, 2

or

.comm min, 2

to put aside space for two bytes (one word) in the bss section. The point of the bss section is that the loader will allocate space and set the content to zero on load, but it won't take up space in your file on disk.

.lcomm is if you only need to refer to min from inside the file where you use .lcomm. comm is if you need to refer to min from other files (so the linker will make it available to other files).

If you prefer to use the data section, which will put the zeros in your file and take up space on disk, then this, placed in the data section, should work:

min:
    .fill 2
