Here is how bytecode for instructions inside functions is emitted.

• §2. Where bytecode comes out
• §5. Structural

• §17. Labels

§1. Introduction. Many sections of runtime need to create functions by explicitly giving their bytecode. This is quite verbose, but with practice easy enough to read. For example, here's bytecode equivalent to return 13:

    EmitCode::inv(RETURN_BIP);
    EmitCode::down();
        EmitCode::val_number(13);
    EmitCode::up();

We conventionally indent this code to reflect the structure of what is being generated, so that the source code in this module looks like the Inter tree structure which emerges.

§2. Where bytecode comes out. We are generating a hierarchical structure and not a stream, so we need the ability to move the point at which new opcodes are being spawned. This is that point

inter_bookmark *EmitCode::at?Usage of EmitCode::at:
§6(void) {
    return Produce::at(Emit::tree());
}

§3. These should always be used in ways guaranteed to match:

• ● EmitCode::down shifts us so that we are now creating bytecode below the instruction last emitted, not after it.
• ● EmitCode::up then returns us back to where we were.

§9. Either/or property testing. This compiles code for the test N has prn, that is, compiles a condition which is true if the value of prn for N is true, and correspondingly false for false.

void EmitCode::test_if_iname_has_property?Usage of EmitCode::test_if_iname_has_property:
Parse Name Properties - §8, §10(kind *K, inter_name *N, property *prn) {
    EmitCode::test_if_symbol_has_property(K, InterNames::to_symbol(N), prn);
}

Showme Command - §6.2(kind *K, inter_symbol *S, property *prn) {
    if (RTProperties::stored_in_negation(prn)) {
        EmitCode::inv(NOT_BIP);

            EmitCode::inv(PROPERTYVALUE_BIP);
            EmitCode::down();
                EmitCode::val_iname(K_value, RTKindIDs::weak_iname(K_object));
                EmitCode::val_symbol(K, S);
                EmitCode::val_iname(K_value,
                    RTProperties::iname(EitherOrProperties::get_negation(prn)));
            EmitCode::up();
        EmitCode::up();
    } else {
        EmitCode::inv(PROPERTYVALUE_BIP);
        EmitCode::down();
            EmitCode::val_iname(K_value, RTKindIDs::weak_iname(K_object));
            EmitCode::val_symbol(K, S);
            EmitCode::val_iname(K_value, RTProperties::iname(prn));
        EmitCode::up();
    }
}

§10. Casts. These are value conversions from one kind to another. In some simple cases, this can be achieved with an Inter cast:

void EmitCode::cast?Usage of EmitCode::cast:
Kind Constructors - §32.3.6.1, §32.3.6.2(kind *F, kind *T) {
    Produce::cast(Emit::tree(), F, T);
}

§11. This allows more complex cases, though:

int EmitCode::cast_possible?Usage of EmitCode::cast_possible:
§12(kind *F, kind *T) {
    F = Kinds::weaken(F, K_object);
    T = Kinds::weaken(T, K_object);
    if ((T) && (F) && (T->construct != F->construct) &&
        (Kinds::Behaviour::definite(T)) && (Kinds::Behaviour::definite(F)) &&
        (Kinds::eq(F, K_object) == FALSE) &&
        (Kinds::eq(T, K_object) == FALSE) &&
        (T->construct != CON_property))
        return TRUE;
    return FALSE;
}

§12. Casts are in many cases implicit, so that nothing need be done, and the following simply returns TRUE to indicate success. But in a few cases, a function call must be inserted, with a name like SNIPPET_TY_to_TEXT_TY; in such cases, this function must exist in the kits somewhere.

int EmitCode::casting_call(kind *F, kind *T, int *down) {
    if (EmitCode::cast_possible(F, T)) {
        if (Str::len(Kinds::Behaviour::get_identifier(T)) == 0) {
            return TRUE;
        }
        if ((Kinds::FloatingPoint::uses_floating_point(F)) &&
            (Kinds::FloatingPoint::uses_floating_point(T))) {
            return TRUE;
        }
        TEMPORARY_TEXT(N)
        WRITE_TO(N, "%S_to_%S",
            Kinds::Behaviour::get_identifier(F),
            Kinds::Behaviour::get_identifier(T));
        inter_name *iname = HierarchyLocations::find_by_name(Emit::tree(), N);
        DISCARD_TEXT(N)
        EmitCode::call(iname);
        *down = TRUE;
        EmitCode::down();
        if (Kinds::Behaviour::uses_block_values(T)) Frames::emit_new_local_value(T);
        return TRUE;
    }
    return FALSE;
}
