所以,我尝试将lua字节码指令转换为向量,问题是这个函数的类型是向量,我试图向函数本身声明一个向量,也就是翻译器的向量。,emplace_back。例如:
std::vector<Instruction*> translate_instr(lua_State* L, Proto* vP, int idx) {
auto vanilla_instr = vP->code[inum];
auto vanilla_op = GET_OPCODE(vanilla_instr);
auto custom_instr_32 = U_CREATE_INSTR(); // Creates new custom instruction
switch (vanilla_op) {
case OP_CALL:
case OP_TAILCALL: {
U_SET_OPCODE(luau_instr_32, custom_opcodes::MLUA_OP_CALL); // Set opcode's byte identifier to custom byte identifier of OP_CALL
U_SETARG_A(luau_instr_32, GETARG_A(vanilla_instr)); // Set first arg to custom a arg
U_SETARG_B(luau_instr_32, GETARG_B(vanilla_instr)); // Set 2nd arg to custom B arg
U_SETARG_C(luau_instr_32, GETARG_B(vanilla_instr)); // Set third arg to custom C arg
translate_instr.push_back(custom_instr_32);
break;
}
}
}translate_instr.push_back(custom_instr_32);行不起作用。
下面是我想要的名称:
auto* L = luaL_newstate();
luaL_openlibs(L);
auto lcl = reinterpret_cast<const LClosure*>(lua_topointer(L, -1));
auto p = lcl->p;
for (auto i = 0; i < p->sizecode; ++i) {
std::vector<Instruction*> custom_instr_vec[i] = translate_instr(L, P, i);
}任何类似的事情对我来说都很好,我只是累了,什么都想不出来。

不完全清楚你想要做什么,但我假设你想要的是:
std::vector<Instruction*> custom_instr_vec;
for (auto i = 0; i < p->sizecode; ++i) {
custom_instr_vec.push_back(translate_instr(L, P, i));
}std::vector<Instruction*> custom_instr_vec[i]将声明一个大小为i的向量数组,因为i不是编译时间常量,因此不是有效的c++。
在translate_instr中,你需要声明一个vector来保存你的结果,然后返回它:
std::vector<Instruction*> translate_instr(lua_State* L, Proto* vP, int idx) {
std::vector<Instruction*> result;
auto vanilla_instr = vP->code[inum];
auto vanilla_op = GET_OPCODE(vanilla_instr);
auto custom_instr_32 = U_CREATE_INSTR(); // Creates new custom instruction
switch (vanilla_op) {
case OP_CALL:
case OP_TAILCALL: {
U_SET_OPCODE(luau_instr_32, custom_opcodes::MLUA_OP_CALL); // Set opcode's byte identifier to custom byte identifier of OP_CALL
U_SETARG_A(luau_instr_32, GETARG_A(vanilla_instr)); // Set first arg to custom a arg
U_SETARG_B(luau_instr_32, GETARG_B(vanilla_instr)); // Set 2nd arg to custom B arg
U_SETARG_C(luau_instr_32, GETARG_B(vanilla_instr)); // Set third arg to custom C arg
result.push_back(custom_instr_32);
break;
}
}
return result;
