asm ("MRS %0, CPSR" : "=r" (irq) : ); error in IAR

Vinit B. (vinitbidkar) OP 2008-09-10 07:53 #1174291

Device: AT91SAM7X256
Compiler: IAR EWARM v 5.20

Code snippet:

1) void function_1 (void)
2) {
3)     char irq_status;
4)     asm ("MRS %0, CPSR" : "=r" (irq_status) : );
5) }

Error given by compiler:
AT line 4, expected ")" after the first :

Is there a different format to be followed for IAR?

That syntax for inline assembler is a GCC-specific extension. IAR should
have something similar.
