Comment 16 for bug 1746765

I did some more testing with binutils-2.30 on arm64 randconfig kernels. One major issue I came across was CONFIG_MODVERSIONS, which causes an error for each exported symbol.

aarch64-linux-ld: init/main.o: relocation R_AARCH64_ABS32 against `__crc_system_state' can not be used when making a shared object
aarch64-linux-ld: init/version.o: relocation R_AARCH64_ABS32 against `__crc_init_uts_ns' can not be used when making a shared object
aarch64-linux-ld: init/do_mounts.o: relocation R_AARCH64_ABS32 against `__crc_name_to_dev_t' can not be used when making a shared object
aarch64-linux-ld: init/init_task.o: relocation R_AARCH64_ABS32 against `__crc_init_task' can not be used when making a shared object
aarch64-linux-ld: arch/arm64/kernel/fpsimd.o: relocation R_AARCH64_ABS32 against `__crc_kernel_neon_busy' can not be used when making a shared object
aarch64-linux-ld: arch/arm64/kernel/process.o: relocation R_AARCH64_ABS32 against `__crc___stack_chk_guard' can not be used when making a shared object
aarch64-linux-ld: arch/arm64/kernel/stacktrace.o: relocation R_AARCH64_ABS32 against `__crc_save_stack_trace_tsk' can not be used when making a shared object

While changing one of the .S files, I also ran into a linker crash:

 aarch64-linux-ld: arch/arm64/kernel/head.o: relocation R_AARCH64_ABS32 against `__rela_offset' can not be used when making a shared object
11:39 PM cross-gcc/bin/aarch64-linux-ld: BFD (GNU Binutils) 2.30 internal error, aborting at /home/arnd/git/binutils/bfd/elfnn-aarch64.c:5279 in elf64_aarch64_final_link_relocate
11:40 PM aarch64-linux-ld: Please report this bug.

This evidently was caused by the same two instructions that came up earlier:

       ldr w9, =__rela_offset // offset to reloc table
       ldr w10, =__rela_size // size of reloc table

After commenting these out, I got no further crashes.
