# 'libcc_kext.a' is runtime support routines for the Darwin kernel and dynamically-loaded drivers.
# No exit/abort/malloc support available, and everything is compiled with '-static -fno-exceptions'.
# Since no exception handling is available, the LIB2_DIVMOD_FUNCS are treated like non-throwing functions.
# Floating support and AltiVec usage are strongly discouraged, but supported.
# 'new' and 'delete' are supported in their non-throwing variants.
# Due to an unfortunate history, throwing-style 'new' and 'delete' are available,
# but they do not throw; new will fail by invoking the 'new_handler' if available, or return zero if not.
# Many standard libgcc routines are not supported in the kernel,
# e.g. 'trampoline', 'clear_cache', 'exit', 'eprintf'.
# These are duplicated betwixt rs6000/t-darwin and i386/t-darwin
# because they are not necessarily identical :-( .
