150# Rename library symbols before use.  If a symbol does not already belong
151# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
152# avoids accidentally linking any kernel symbol against host platform
153# libraries.  The only non-renamed symbols are linkset delimiters and
154# the GOT, which are more a property of the compiler than the kernel.
155#
156# Some toolchains generate unresolved symbols which are supposed to be
157# satisfied by the toolchain itself when the program is linked.
158# Unfortunately, we do not know which of the symbols are generated by
159# the toolchain.  Worse, they vary from platform to platform and
160# toolchain to toolchain.  The good news, however, is that this will
161# be detected by a compile-time failure, so we can fairly easily manage
162# a quirktable here.

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