/* FIXME: cagney/2003-02-02: Should be deprecated or replaced with a
function called get_frame_register_p(). This slightly weird (and
older) variant of get_frame_register() returns zero (indicating the
register value is unavailable/invalid) if either: the register
isn't cached; or the register has been optimized out; or the
register contents are unavailable (because they haven't been
collected in a traceframe). Problem is, neither check is exactly
correct. A register can't be optimized out (it may not have been
saved as part of a function call); The fact that a register isn't
in the register cache doesn't mean that the register isn't
available (it could have been fetched from memory). */
