not fully understand what you're seeking, probably you're looking for
ASSEMBLER_DIALECT.
cut from i386.c
---------------
void
ix86_print_operand (FILE *file, rtx x, int code)
{
if (code)
{
switch (code)
{
case 'A':
switch (ASSEMBLER_DIALECT)
{
case ASM_ATT:
putc ('*', file);
break;
case ASM_INTEL:
/* Intel syntax. For absolute addresses, registers should not
be surrounded by braces. */
if (!REG_P (x))
{
putc ('[', file);
ix86_print_operand (file, x, 0);
putc (']', file);
return;
}
break;
