From: Steven Rostedt <rostedt@goodmis.org>
The mcount_loc sorting for when the values are stored in the Elf_Rela
entries uses the compare_extable() function to do the compares in the
qsort(). That function does handle byte swapping if the machine being
compiled for is a different endian than the host machine. But the
sort_relocs() function sorts an array that pulled in the values from the
Elf_Rela section and has already done the swapping.
Create two new compare functions that will sort the direct values. One
will sort 32 bit values and the other will sort the 64 bit value. One of
these will be assigned to a compare_values function pointer and that will
be used for sorting the Elf_Rela mcount values.

This is what I get on arm64 randconfig builds using clang after your
patch:
failed to sort mcount 'Expected 24260 mcount elements but found 0
': vmlinux
Failed to sort kernel tables
I have not tried to understand what your patch does. See the attached
defconfig for a reproducer.

Can you compile without that commit, run and give me the output from these two programs: ./dump_elf_sym vmlinux __start_mcount_loc __stop_mcount_loc ./dump_elf_rela vmlinux .rela.dyn If the second one fails, remove the '.rela.dyn' and see what that shows. https://rostedt.org/code/dump_elf_sym.c https://rostedt.org/code/dump_elf_rela.c Thanks, -- Steve

Nevermind, Masami told me all I need to do is add LLVM=1 and clang can
handle the cross compiling.
I looked, and sure enough clang on arm64 does it the same way x86 does. So
using the rela items to sort is a gcc thing :-p
Can you try this patch?

It fixes the build issue for me. I tried booting as well, but ran
into a BUG() when I enable ftrace. I assume this is an unrelated
issue, but you can find the output for reference in case this is
relevant.
