-// the visibility of the inline assembly function "__cxa_end_cleanup".
-// We need to keep the visibility of the __cxa_* functions coherent otherwise
-// linking eh_arm.o to resolve __cxa_end_cleanup (eg needed by -frtti
-// -fexceptions) will disappoint the linker by exposing __cxa_type_match and
-// __cxa_begin_cleanup (eg needed by __aeabi_idiv from libgcc.a).
-// Therefore as a simple workaround we just force the visibility to default for
