__asm__ and

__asm__ and

[Shaun Jackman]

Can someone tell me what I'm doing wrong here? When I use this macro, like
void myfunc( void) {
	int_disable();
	// do stuff
	int_enable();
}

#define int_disable() \
    __asm__( \
            "mrs %0, cpsr \n\t" \
            "orr %0, %0, #I_BIT \n\t" \
            "msr cpsr, %0 \n\t" \
            : "=r" : : "cpsr" \
           )

I get the error
cs8900.c:246: parse error before ':' token

This is confusing me. I followed the examples in the info page and I can't 
figure it out.

Thanks,
Shaun

This looks very much like the typical CR+LF (*) error.  GCC used to
fail when processing files that were not uniform in using CR+LF or
just LF for line breaks.  When finding a CR, it would sometimes
interpret that as whitespace after `\', and not merge the lines
together, resulting in this kind of error.  Please make sure this file
doesn't contain embedded CRs and try again.

* CR stands for Carriage Return, or ^M, ASCII 13, whereas LF stands
  for Line Feed, ^J, ASCII 10.
