◆ FixAddress()

virtual lldb::addr_t ABIAArch64::FixAddress ( lldb::addr_t pc,
lldb::addr_t mask )

◆ FixCodeAddress()

lldb::addr_t ABIAArch64::FixCodeAddress ( lldb::addr_t pc)

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.
