The libgcc runtime library provides __register_frame and __deregister_frame functions, which can be used by dynamic code generators to register an .eh_frame section, which contains one or more Call Frame Information records, each consisting of a Common Information Entry record followed by one or more Frame Description Entry records. This libunwind library also provides __register_frame and __deregister_frame functions, but they are aliases for __unw_add_dynamic_fde and __unw_remove_dynamic_fde and thus can only take a single FDE. This patch adds __unw_add_dynamic_eh_frame_section and __unw_remove_dynamic_eh_frame_section functions which explicitly use the .eh_frame format. Clients such as the ORCv2 platform and runtime can check for these functions and use them if unwinding is being provided by libunwind, or fall back to __register_frame and __deregister_frame if unwinding is provided by libgcc.
