-/* Hipe wrappers used by native code for BIFs that disable GC while trapping.
- *
- * Problem:
- * When native code calls a BIF that traps, hipe_mode_switch will push a
- * "trap frame" on the Erlang stack in order to find its way back from beam_emu
- * back to native caller when finally done. If GC is disabled and stack/heap
- * is full there is no place to push the "trap frame".
- *
- * Solution:
- * We reserve space on stack for the "trap frame" here before the BIF is called.
- * If the BIF does not trap, the space is reclaimed here before returning.
- * If the BIF traps, hipe_push_beam_trap_frame() will detect that a "trap frame"
- * already is reserved and use it.
