145# Rename library symbols before use.  If a symbol does not already belong
146# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
147# avoids accidentally linking any kernel symbol against host platform
148# libraries.  The only non-renamed symbols are linkset delimiters and
149# the GOT, which are more a property of the compiler than the kernel.

151# Some toolchains generate unresolved symbols which are supposed to be
152# satisfied by the toolchain itself when the program is linked.
153# Unfortunately, we do not know which of the symbols are generated by
154# the toolchain.  Worse, they vary from platform to platform and
155# toolchain to toolchain.  The good news, however, is that this will
156# be detected by a compile-time failure, so we can fairly easily manage
157# a quirktable here.
