### Steps to reproduce

1. Create shader
2. Add uint with hex, e.g. 0xffffu

### Minimal reproduction project

N/A
FunctionNode *call_function = shader->functions[function_index].function;
						if (call_function) {
							func->return_cache = call_function->get_datatype();
							func->struct_name = call_function->get_datatype_name();
							func->return_array_size = call_function->get_array_size();
							
							FunctionNode *base_function = nullptr;
							{
								BlockNode *b = p_block;
								while (b) {
									if (b->parent_function) {
										base_function = b->parent_function;
										break;
									} else {
										b = b->parent_block;
									}
								}
							}
							ERR_FAIL_COND_V(!base_function, nullptr); 
							for (int i = 0; i < call_function->arguments.size(); i++) {
								int argidx = i + 1;
								if (argidx < func->arguments.size()) {
									bool error = false;
									Node *n = func->arguments[argidx];
									ArgumentQualifier arg_qual = call_function->arguments[i].qualifier;
									bool is_out_arg = arg_qual != ArgumentQualifier::ARGUMENT_QUALIFIER_IN;

										if (n->type == Node::NODE_TYPE_VARIABLE) {
											VariableNode *vn = static_cast<VariableNode *>(n);
