Reading a Function's Return Address

Just put the following in  'file.s'  :

	.seg	"text"
	.global _getaddr
_getaddr:
	retl
	add	%i7,8,%o0

and link in file.s (just pretend it's a C source file).  Now you can just
say :  this_functions_return_address_is  = getaddr(); in the callee.  This
will give you the point in the caller where the callee will return to.
This value minus 8 is the address of the statement which actually called
the function you're in.
