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

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

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