I believe you need to set FRAME_RELATED_P on the sub expressions within
the PARALLEL.  Something like this:

     /* Set RTX_FRAME_RELATED_P on the insn and each member of the
         PARALLEL for the dwarf2 unwinder.  */
      RTX_FRAME_RELATED_P (insn) = 1;
      for (i = 0; i < XVECLEN (PATTERN (insn), 0); i++)
        RTX_FRAME_RELATED_P (XVECEXP (PATTERN (insn), 0, i)) = 1;

Where INSN is the value returned by emit_insn (gen_post_store ...))
