Hi Dave,

Thanks for the quick reply.

I thought I understood it, but this one baffles me:

static int floating(int a, float b, double c, long double d, int e)

i would have guessed this mapped to:

a -> gr26   (sp-36)
b -> fr4L   (sp-40)
c -> fr7    (sp-48)
d -> sp-56
e -> sp-64

but according to gcc, e is at sp-60.

How come?

thanks,
randolph
