arm eabi requires this symbol for static C++ dtors. usually it is provided by libstdc++, but when a C++ program doesn't use the std lib (free-standing), the libc has to provide it. this was encountered while building transmission, which depends on such a C++ library (libutp). this function is nearly identical to __cxa_atexit, but it has the order of argumens swapped for "performance reasons". see page 25 of http://infocenter.arm.com/help/topic/com.arm.doc.ihi0043d/IHI0043D_rtabi.pdf there are other aeabi specific C++ support functions missing, but it is not clear yet that GCC makes use of them so we omit them for the moment. |
