Functions
template<typename AbiTraits >
uint32_t	microfmt::resolve_fp_register (register_context_ref reg_ctx) noexcept
	Resolves the frame-pointer register to use for AbiTraits.
template<typename AbiTraits >
bool	microfmt::resolve_frame_slot_offsets (register_context_ref reg_ctx, ptrdiff_t &out_fp_slot_offset, ptrdiff_t &out_ra_slot_offset) noexcept
	Resolves the FP-relative saved-FP/saved-RA slot offsets to use for AbiTraits's naive FP-chain walking (fp_unwinder_tag).
