Due to work adjustment, it is my pleasure and duty to go on with this work
from now on. As discussed with Youling offline to reach an agreement, I'll
make this patch series as simple and clear as possible, maybe this is going
to progress in the right direction.
This version is based on 6.5-rc1, the patches apply cleanly to the latest
objtool/core branch of tip/tip.git tree too, most of the changes are under
tools/objtool/arch/loongarch and arch/loongarch.
To be honest, there still exist some objtool warnings, I will try my best
to fix them in the later versions or the other separate patches.
Tiezhu Yang (6):
objtool/LoongArch: Enable objtool to be built
objtool/LoongArch: Implement instruction decoder
objtool/x86: Separate arch-specific and generic parts
objtool/LoongArch: Enable orc to be built
objtool: Add skipped member in struct reloc
LoongArch: Add ORC unwinder support
