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