"\n\t" in inline asm

[Martynas Kunigelis]

Good day,

I use inline assembly quite often and I am a little disturbed by the
need to append "\n\t" to the end of every inline assembly line. This
makes the code much less readable, so I end up using a preprocessor hack
like this:

#define _ "\n\t"

asm (
  "movl %0,%1"  _
  "decl %2"     _
  "int $0x80"
  : /* this is just an example */
  : "=r" (0) /* whatever */
);

#undef _

While experimenting I tried using commas at the end of each line, like
this:

asm (
  "movl %0,%1",
  "decl %2",     
  "int $0x80"
  : /* this is just an example */
  : "=r" (0) /* whatever */
);

It compiled w/o problems, but the resulting .s file had only the last
line from the inline asm statement, that is "int $0x80". It seems as if
it was evaluated as a regular C statement, like  "a = 1, 2, 3, 4;" would
result in a == 4.

I would like to make a suggestion to add somewhat more special handling
of inline asm() statements, and make a comma appent the "cursed" "\n\t"
to each line. That wouldn't break any existing code and it would allow
one to "beautify" the inline assembly code a lot more.
