+;         Name: __sigsetjmp
+;  Description: Save the current context so
+;               a nr_longjmp works later.
+;        Input: %o0: jmp_buf: (ptr to) array to store context in
+;       Output: %o0 = 0 the first time we're called, or
+;               whatever longjmp returns later
+; Side Effects: Uses %g0
+;    CWP Depth: 0
