-We actually start executing at the `sethi', since the pushing of the
-registers (as arguments) is done by PUSH_DUMMY_FRAME.  If this were
-real code, the arguments for the function called by the CALL would be
-pushed between the list of ST insns and the CALL, and we could allow
-it to execute through.  But the arguments have to be pushed by GDB
-after the PUSH_DUMMY_FRAME is done, and we cannot allow these ST
-insns to be performed again, lest the registers saved be taken for
-arguments.  */
