◆ FixCodeAddress()

lldb::addr_t ABISysV_arm64::FixCodeAddress ( lldb::addr_t pc )

overridevirtual

Some targets might use bits in a code address to indicate a mode switch.

ARM uses bit zero to signify a code address is thumb, so any ARM ABI plug-ins would strip those bits.

		unsigned	protection_key,
		uint32_t	original_permissions )

overridevirtual

Get the effective memory permissions that result when the permissions referred to by a protection key are applied to the original permissions.

This is intended for architectures that have some sort of permission overlay system. Where the protection key is used to look up a set of permissions that modifies the original permissions.

Returns: the overlay permissions (that the protection key refers to) and the effective permissions. If the target does not have an overlay system, or it does and the protection key is invalid, returns nullopt.
