Well, there is the documentation, e.g.:
http://gcc.gnu.org/onlinedocs/gcc-4.0.3/gcc/Other-Builtins.html
Or if you want to look at the source code, look at builtins.def and
look for calls to add_builtin_function or lang_hooks.builtin_function
in config/CPU/*.c.
Well, that will tell you about functions like __builtin_memset:
functions which are specially recognized and handled by the compiler.
__cxa_begin_catch is a different sort of function, it is a support
function which is called by the compiler. For the complete set of
those functions, look at libgcc*.* and libsupc++.a in the installed
tree (generally under lib/gcc/TARGET/VERSION). Those functions
generally have no user-level documentation.
