-- Note [Subsections Via Symbols]
-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- If we are using the .subsections_via_symbols directive
-- (available on recent versions of Darwin),
-- we have to make sure that there is some kind of reference
-- from the entry code to a label on the _top_ of the info table,
-- so that the linker will not think it is unreferenced and dead-strip
-- it. That's why the label is called a DeadStripPreventer (_dsp).
--
-- The LLVM code gen already creates `iTableSuf` symbols, where
-- the X86 would generate the DeadStripPreventer (_dsp) symbol.
-- Therefore all that is left for llvm code gen, is to ensure
-- that all the `iTableSuf` symbols are marked as used.
-- As of this writing the documentation regarding the
-- .subsections_via_symbols and -dead_strip can be found at
-- <https://developer.apple.com/library/mac/documentation/DeveloperTools/Reference/Assembler/040-Assembler_Directives/asm_directives.html#//apple_ref/doc/uid/TP30000823-TPXREF101>

    NOTE: This is a bit hacky.

    With the `tablesNextToCode` info tables look like this:
    ```
      <info table data>
    label_info:
      <info table code>
    ```
    So actually info table label points exactly to the code and we can mark
    the label as @function. (This is required to make perf and potentially other
    tools to work on Haskell binaries).
    This usually works well but it can cause issues with a linker.
    A linker uses different algorithms for the relocation depending on
    the symbol type.For some reason, a linker will generate JUMP_SLOT relocation
    when constructor info table is referenced from a data section.
    This only happens with static constructor call so
    we mark _con_info symbols as `@object` to avoid the issue with relocations.

    @SimonMarlow hack explanation:
    "The reasoning goes like this:

    * The danger when we mark a symbol as `@function` is that the linker will
      redirect it to point to the PLT and use a `JUMP_SLOT` relocation when
      the symbol refers to something outside the current shared object.
      A PLT / JUMP_SLOT reference only works for symbols that we jump to, not
      for symbols representing data,, nor for info table symbol references which
      we expect to point directly to the info table.
    * GHC generates code that might refer to any info table symbol from the text
      segment, but that's OK, because those will be explicit GOT references
      generated by the code generator.
    * When we refer to info tables from the data segment, it's either
      * a FUN_STATIC/THUNK_STATIC local to this module
      * a `con_info` that could be from anywhere

    So, the only info table symbols that we might refer to from the data segment
    of another shared object are `con_info` symbols, so those are the ones we
    need to exclude from getting the @function treatment.
    "

    A good place to check for more
    https://gitlab.haskell.org/ghc/ghc/wikis/commentary/position-independent-code

    Another possible hack is to create an extra local function symbol for
    every code-like thing to give the needed information for to the tools
    but mess up with the relocation. https://phabricator.haskell.org/D4730
