C++ (Cpp) ALU_any_int Examples

Example #1

File: cpu.c Project: actraiser/dust-bundle-c64-mac

// insert byte until PC fits condition
static enum eos_t PO_align(void) {
	intval_t	and,
			equal,
			fill,
			test	= CPU_pc.intval;

	// make sure PC is defined.
	if ((CPU_pc.flags & MVALUE_DEFINED) == 0) {
		Throw_error(exception_pc_undefined);
		CPU_pc.flags |= MVALUE_DEFINED;	// do not complain again
		return SKIP_REMAINDER;
	}

	and = ALU_defined_int();
	if (!Input_accept_comma())
		Throw_error(exception_syntax);
	equal = ALU_defined_int();
	if (Input_accept_comma())
		fill = ALU_any_int();
	else
		fill = CPU_now->default_align_value;
	while ((test++ & and) != equal)
		Output_8b(fill);
	return ENSURE_EOS;
}

Example #2

File: basics.c Project: martinpiper/ACME

// Reserve space by sending bytes of given value ("!fi" / "!fill" pseudo opcode)
static enum eos_t PO_fill(void) {
	intval_t	fill	= FILLVALUE_FILL,
			size	= ALU_defined_int();

	if(Input_accept_comma())
		fill = ALU_any_int();
	while(size--)
		Output_8b(fill);
	return(ENSURE_EOS);
}

Example #3

File: basics.c Project: martinpiper/ACME

// Helper function for !8, !16, !24 and !32 pseudo opcodes
static enum eos_t output_objects(void (*fn)(intval_t)) {
	do
		fn(ALU_any_int());
	while(Input_accept_comma());
	return(ENSURE_EOS);
}
