If a symbol does not already belong 53# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns". This 54# avoids accidentally linking any kernel symbol against host platform 55# libraries. The only non-renamed symbols are linkset delimiters and 56# the GOT, which are more a property of the compiler than the kernel. 57# 58# Some toolchains generate unresolved symbols which are supposed to be 59# satisfied by the toolchain itself when the program is linked. 60# Unfortunately, we do not know which of the symbols are generated by 61# the toolchain. Worse, they vary from platform to platform and 62# toolchain to toolchain. The good news, however, is that this will 63# be detected by a compile-time failure, so we can fairly easily manage 64# a quirktable here. 65.if ${MACHINE_CPU} == "mips" 66_SYMQUIRK='|_gp_disp' 67.elif ${MACHINE_CPU} == "hppa" 68_SYMQUIRK='|\$$\$$' 69.endif 70__archivebuild: .USE 71 ${_MKTARGET_BUILD} 72 rm -f ${.TARGET} 73 ${AR} ${_ARFL} ${.TARGET} `NM=${NM} ${LORDER} ${.ALLSRC:M*o} | ${TSORT}` 74 ${NM} -go ${.TARGET} | ${TOOL_AWK} ' \ 75 $$NF!~/^(rump|RUMP|__|_GLOBAL_OFFSET_TABLE'${_SYMQUIRK}')/ \ 76 {printf "%s rumpns_%s\n", $$NF, $$NF}' \ 77 | sort | uniq > renametab.${.TARGET} 78 ${OBJCOPY} --preserve-dates --redefine-syms \ 79 renametab.${.TARGET} ${.TARGET} 80 rm -f renametab.${.TARGET} 81 ${AR} ${_ARRANFL} ${.TARGET} 82
