I know this is titled basic implementation, so these are likely some TODOs for a full implementation:
* Floating point/MVE registers. In all known implementations these are d0-d16.
* Accounting for security extensions like v8.1-m PACBTI, where the return address may be signed/authenticated, and BTI landing pads may be needed at certain points.
