Other than syntax that I am not used to, GCC do this better.

You should get yourself NASM which isn't inline but has Intel style
which I find much easier since it is more or less  TASM compatible
except for macros.

Also I think I got this for macro from Brennan's webpage. If someone
else don't give you the URL, let me know

#define COPY32(dest, src, numwords) \
__asm__ __volatile__ ( \
  "cld\n\t" \
  "rep\n\t" \
  "movsl" \
  : : "S" (src), "D" (dest), "c" (numwords) \
  : "%ecx", "%esi", "%edi" )

#define times3(arg1, arg2) \
__asm__ ( \
  "leal (%0,%0,2),%0" \
  : "=r" (arg2) \
  : "0" (arg1) );


This syntax should work the same for any variables (just remove #define.)
