• This way, a function cannot modify a variable that is not passed to it in the list of arguments (with the exception of global variables). Pass by value or pass by reference? or pointer? 在C++ 中,当一个参数 按值传
BindNativeFunction(engine, *object, "createModuleContext", moduleName, JsBaseContext::CreateModuleContext); return objValue; } 接下来,继续分析一下x19 需要加上#8的原因。下面3条指令是调用 GetHandleAddr(const EcmaVM *vm, uintptr_t localAddress) 方法,这样对应起来[x19, #8]保存的应该是address。

The return type of a function cannot be a function type or an array type (but can be a pointer or reference to those). As with any declaration, attributes that appear before the declaration and the attributes that appear immediately after the identifier within the declarator both apply to ...
This function is invoked before the main function as a part of process initialization. The return address is another type of code pointer. To protect return addresses from leakage, the compiler extension needs to instrument instructions to copy return addresses to CPP pages and remove their value ...

// I’ve omitted the function pointer code. float _return_value = _il2cpp_pinvoke_func(___v); return _return_value; 同样的,参数是按值传递的,就像上面那个int的例子一样。如果我们想改变Vector的值,我们必须按引用传递这个变量,就像下面SetX函数(HelloWorld_SetX_m6)所做的那样: ...
