	* gdb.arch/amd64-entry-value.cc (c, a, b, amb_z, amb_y, amb_x, amb)
	(amb_b, amb_a): New.
	(main): Call a and b.
	* gdb.arch/amd64-entry-value.exp (tailcall: breakhere, tailcall: bt)
	(tailcall: p i, tailcall: p j, set $sp0=$sp, up, p $sp0 == $sp, frame 3)
	(p $sp0 + sizeof (void *) == $sp, ambiguous: breakhere, ambiguous: bt):
	New tests.
