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

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

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