A recent change only initializes the regs.how[] during Dwarf unwinding
which resulted in an uninitialized offset used in return address signing
and random failures during unwinding. The fix is to encode the return
address signing state in REG_UNSAVED and REG_UNDEFINED.
2023-01-10 Wilco Dijkstra <Wilco.Dijkstra@arm.com>
PR target/107678
* unwind-dw2.c (RA_SIGNED_BIT): Remove.
* unwind-dw2-execute_cfa.h: Use REG_UNSAVED/UNDEFINED
to encode return address signing state.
* config/aarch64/aarch64-unwind.h (aarch64_demangle_return_addr)
Check current return address signing state.
(aarch64_frob_update_contex): Remove.
