If a symbol does not already belong 109# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns". This 110# avoids accidentally linking any kernel symbol against host platform 111# libraries. The only non-renamed symbols are linkset delimiters and 112# the GOT, which are more a property of the compiler than the kernel. 113# 114# Some toolchains generate unresolved symbols which are supposed to be 115# satisfied by the toolchain itself when the program is linked. 116# Unfortunately, we do not know which of the symbols are generated by 117# the toolchain. Worse, they vary from platform to platform and 118# toolchain to toolchain. The good news, however, is that this will 119# be detected by a compile-time failure, so we can fairly easily manage 120# a quirktable here. 121# 122# We also allow calling ourselves externally with e.g.: 123# make -f /sys/rump/Makefile.rump RUMP_SYMREN=ffs.kobj 124# 125.if ${MACHINE_CPU} == "mips" 126_SYMQUIRK='|_gp_disp' 127.elif ${MACHINE_CPU} == "hppa" 128_SYMQUIRK='|\$$\$$' 129.elif ${MACHINE_ARCH} == "powerpc64" 130_SYMQUIRK="|PF_funcs" 131.endif 132 133# 134# Prefix quirks.
