[PATCH v2 0/5] Add jump table support for objtool on LoongArch

[Tiezhu Yang]

This series is based on 6.12-rc6, tested with the upstream mainline
binutils, GCC and Clang, all the changes are under tools/objtool and
arch/loongarch.

It is time to remove the compiler option -fno-jump-tables to enable
jump table for objtool if the compiler is GCC and it has the compiler
option -mannotate-tablejump, the next work is to add the corresponding
support with Clang after addressing some corner issues due to different
compiler behaviors.

Tiezhu Yang (5):
  objtool: Handle various symbol types for rodata
  objtool: Handle special cases of discard.reachable
  objtool/LoongArch: Add support for switch table
  objtool/LoongArch: Add support for goto table
  LoongArch: Enable jump table with GCC for objtool
