55# Rename library symbols before use.  If a symbol does not already belong
56# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
57# avoids accidentally linking any kernel symbol against host platform
58# libraries.  The only non-renamed symbols are linkset delimiters and
59# the GOT, which are more a property of the compiler than the kernel.
60#
61# Some toolchains generate unresolved symbols which are supposed to be
62# satisfied by the toolchain itself when the program is linked.
63# Unfortunately, we do not know which of the symbols are generated by
64# the toolchain.  Worse, they vary from platform to platform and
65# toolchain to toolchain.  The good news, however, is that this will
66# be detected by a compile-time failure, so we can fairly easily manage
67# a quirktable here.
