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