Nathan Chancellor 22235ef34a MIPS: VDSO: Allow ld.lld to link the VDSO ... Currently, when linking with ld.lld, this warning pops up: arch/mips/vdso/Makefile:70: MIPS VDSO requires binutils >= 2.25 CONFIG_LD_VERSION is set with scripts/ld-version.sh, which is specific to GNU ld. It returns 0 for ld.lld so CONFIG_MIPS_LD_CAN_LINK_VDSO does not set. ld.lld has a completely different versioning scheme (as it follows LLVM's versioning) and it does not have the issue mentioned in the comment block so it should be allowed to link the VDSO. With this patch, the VDSO successfully links and shows P_MIPS_PC32 in vgettimeofday.o. $ llvm-objdump -Dr arch/mips/vdso/vgettimeofday.o | grep R_MIPS_PC32 00000024: R_MIPS_PC32 _start 000000b0: R_MIPS_PC32 _start 000002bc: R_MIPS_PC32 _start 0000036c: R_MIPS_PC32 _start 00000468: R_MIPS_PC32 _start Reported-by: Dmitry Golovin <dima@golovin.in> Signed-off-by: Nathan Chancellor <natechancellor@gmail.com> Link: https://github.com/ClangBuiltLinux/linux/issues/785 Link: e364e2e9ce Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>		2020-05-12 10:02:11 +02:00
