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

130# satisfied by the toolchain itself when the program is linked.
131# Unfortunately, we do not know which of the symbols are generated by
132# the toolchain.  Worse, they vary from platform to platform and
133# toolchain to toolchain.  The good news, however, is that this will
134# be detected by a compile-time failure, so we can fairly easily manage
135# a quirktable here.
