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

125# satisfied by the toolchain itself when the program is linked.

127# the toolchain.  Worse, they vary from platform to platform and
128# toolchain to toolchain.  The good news, however, is that this will
129# be detected by a compile-time failure, so we can fairly easily manage
130# a quirktable here.
