The names are also important given the new functions created just below. Also, clarify comments in lisp-union.h and lisp-disunion.h about the use of the functions. * lisp.h: New functions STORE_VOID_IN_LISP and GET_VOID_FROM_LISP. These are different from the above in that the source is a void * (previously, you had to use make_opaque_ptr()). * eval.c (restore_lisp_object): * eval.c (record_unwind_protect_restoring_lisp_object): * eval.c (struct restore_int): * eval.c (restore_int): * eval.c (record_unwind_protect_restoring_int): * eval.c (free_pointer): * eval.c (record_unwind_protect_freeing): * eval.c (free_dynarr): * eval.c (record_unwind_protect_freeing_dynarr): * eval.c (unbind_to_1): Use STORE_VOID_IN_LISP and GET_VOID_FROM_LISP to eliminate the use of make_opaque_ptr() and mostly eliminate Lisp consing entirely in the use of these various record_unwind_protect_* functions as well as internal_bind_* (e.g. internal_bind_int). * tests.c: * tests.c (Ftest_store_void_in_lisp): * tests.c (syms_of_tests): * tests.c (vars_of_tests): Add an C-assert-style test to test STORE_VOID_IN_LISP and GET_VOID_FROM_LISP to make sure the same value comes back that was put in.
