      objtool: Add ORC unwind table generation · 627fce14
      Josh Poimboeuf authored
      Now that objtool knows the states of all registers on the stack for each
      instruction, it's straightforward to generate debuginfo for an unwinder
      to use.
      Instead of generating DWARF, generate a new format called ORC, which is
      more suitable for an in-kernel unwinder.  See
      Documentation/x86/orc-unwinder.txt for a more detailed description of
      this new debuginfo format and why it's preferable to DWARF.
