Example:
<type specifier> _ _regparam3 <function name>
Specifies the number of parameter registers. Functions specified by
_ _regparam2 use the ER0 and ER1 registers (the R0 and R1 registers for
the H8/300). Functions specified by _ _regparam3 use the ER0, ER1, and
ER2 registers (the R0, R1, and R2 registers for the H8/300).
void _ _regparam2 func1(long a, int b, int c, long d);
void _ _regparam3 func2(long a, int b, int c, long d);
int long a; int b; int c; long d;
void main(void)
{
funcl(a, b, c, d);
value of the register may be changed by the call to the function with
_ _noregsave or #pragma noregsave.
