113# Rename library symbols before use.  If a symbol does not already belong
114# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
115# avoids accidentally linking any kernel symbol against host platform
116# libraries.  The only non-renamed symbols are linkset delimiters and
117# the GOT, which are more a property of the compiler than the kernel.
118#
119# Some toolchains generate unresolved symbols which are supposed to be
120# satisfied by the toolchain itself when the program is linked.
121# Unfortunately, we do not know which of the symbols are generated by
122# the toolchain.  Worse, they vary from platform to platform and
123# toolchain to toolchain.  The good news, however, is that this will
124# be detected by a compile-time failure, so we can fairly easily manage
125# a quirktable here.

128# make -f /sys/rump/Makefile.rump RUMP_SYMREN=ffs.kobj
