Let's say we have got following code:

Code:

.....
mov     eax, str1
mov     eax, str2
......
str1 db "string1",0
str2 db "striffng1",0
str3 db "striffng1",0
str4 db "strifng1",0
     db "asdsad",0
str5 db "strifngs",0

Is there any way to force fasm to strip (obviously without any `external` help) unreferenced strings, like str3, str4 and str5 in the above example?

Code:

struc db [args]{
common
  if used .
    . db args
  end if}

The code above doesn't works?

personally i don't think this is a good idea. db should work as expected. i suggest to make another macro for this purpose, like:

Code:

struc string [text] {
common
  if used .
    . db text,0
  end if
}
string "I'm not a string"
string "hovno",10,13,"frndzalica"

Prevents lot of confusion and stupid bugs

sorry, example was wrong. usage should look like this:

Code:

_not_a_string string "I'm not a string" 
_hovno string "hovno",10,13,"frndzalica"
