- 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). */
