If a symbol does not already belong 43# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns". This 44# avoids accidentally linking any kernel symbol against host platform 45# libraries. The only non-renamed symbols are linkset delimiters and 46# the GOT, which are more a property of the compiler than the kernel. 47# 48# Some toolchains generate unresolved symbols which are supposed to be 49# satisfied by the toolchain itself when the program is linked. 50# Unfortunately, we do not know which of the symbols are generated by 51# the toolchain. Worse, they vary from platform to platform and 52# toolchain to toolchain. The good news, however, is that this will 53# be detected by a compile-time failure, so we can fairly easily manage 54# a quirktable here. 55.if ${MACHINE_CPU} == "mips" 56_SYMQUIRK='|_gp_disp' 57.elif ${MACHINE_CPU} == "hppa" 58_SYMQUIRK='|\$$\$$' 59.endif 60__archivebuild: .USE 61 ${_MKTARGET_BUILD} 62 rm -f ${.TARGET} 63 ${AR} ${_ARFL} ${.TARGET} `NM=${NM} ${LORDER} ${.ALLSRC:M*o} | ${TSORT}` 64 ${NM} -go ${.TARGET} | ${TOOL_AWK} ' \ 65 $$NF!~/^(rump|RUMP|__|_GLOBAL_OFFSET_TABLE'${_SYMQUIRK}')/ \ 66 {printf "%s rumpns_%s\n", $$NF, $$NF}' \ 67 | sort | uniq > renametab.${.TARGET} 68 ${OBJCOPY} --preserve-dates --redefine-syms \ 69 renametab.${.TARGET} ${.TARGET} 70 rm -f renametab.${.TARGET} 71 ${AR} ${_ARRANFL} ${.TARGET} 72
