Hello,
I am developing application on OMAP3530-beagleboard using code sourcery tool chain.
I have used assembly function in my C application.Function has 5 argument it's called from another c function.
function like: void routine(signed char *a, int b, signed char *c, unsigned char *d, unsigned int *e)
{
asm volatile{
........assembly syntaxs....
};
}
Here, function argument a to d are stored in r0 to r3 but argument e either go to stack or store into r4 to r12 register as per called function ?
How can i write assembly syntax in my assembly function to get value of argument e in any specific register so I can use in my function correctly?
How can I write assembly syntax so assembly function parameter passing become independent of called function variable usage means I can use this routine function any other application without doing changed inside the assembly syntax to catch parameter value ?
Thanks,
