为了简单起见我们只使用exit系统调用 .global__start#告诉ld入口点.text__start:li$v0,4000+1#exitsyscall 编译结果如下 image.png TCG前端如何处理syscall 解析syscall指令 首先gen_intermediate_code()调用gen_tb_start(tb)生成翻译块序言, 然后调用decode_opc()翻译MIPS为IR ...

TCG(Tiny Code Generator)后端:如果硬件虚拟化不可用,QEMU可以使用TCG后端进行模拟。TCG是一种基于解释的虚拟机,性能通常较低,但可以在不支持硬件虚拟化的系统上工作。 1.2 — 虚拟机创建流程 当要使用KVM作为加速器和后端选项时,可以在QEMU的启动命令行中加入--enable-kvm,接下来参数解析会进...
