37# Rename library symbols before use.  If a symbol does not already belong
38# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
39# avoids accidentally linking any kernel symbol against host platform
40# libraries.  The only non-renamed symbols are linkset delimiters and
41# the GOT, which are more a property of the compiler than the kernel.
42#
43# Some toolchains generate unresolved symbols which are supposed to be
44# satisfied by the toolchain itself when the program is linked.
45# Unfortunately, we do not know which of the symbols are generated by
46# the toolchain.  Worse, they vary from platform to platform and
47# toolchain to toolchain.  The good news, however, is that this will
48# be detected by a compile-time failure, so we can fairly easily manage
49# a quirktable here.
