可以将C/C ++软件编译成字节码以便以后执行吗? (独立于体系结构的UNIX软件.) [英] Can C/C++ software be compiled into bytecode for later execution? (Architecture independent unix software.)

问题描述

我想将现有软件编译成演示文稿，然后再在不同的体系结构(和OS)上运行.

I would want to compile existing software into presentation that can later be run on different architectures (and OS).

为此，我需要一个可以在另一个arch/OS上轻松运行/模拟的(字节)代码( LLVM IR?有一些RISC装配?)

For that I need a (byte)code that can be easily run/emulated on another arch/OS (LLVM IR? Some RISC assemby?)

一些随机的想法:

• 编译为JVM字节码并与Java一起运行.太严格了吗?有C编译器吗?
• MS CIL.可以使用C编译器吗?
• LLVM?可以稍后再进行中间代理吗?
• 编译为RISC拱门，例如MMIX.那系统调用呢?

然后有系统调用映射的东西，例如BSD具有系统调用转换层.

Then there is the system call mapping thing, but e.g. BSD have system call translation layers.

是否已经有可以将C/C ++编译为某些内容的系统，以后可以在另一个体系结构上使用解释器运行该系统?

Are there any already working systems that compile C/C++ into something that can later be run with an interpreter on another architecture?

我可以将现有的unix软件编译为不太低级的二进制文件，比运行完整的x86模拟器更容易模拟"二进制文件吗?比XEN HVM更像JVM.

Could I compile existing unix software into not-so-lowlevel binary, which could be "emulated" more easily than running full x86 emulator? Something more like JVM than XEN HVM.

推荐答案

There are several C to JVM compilers listed on Wikipedia's JVM page. I've never tried any of them, but they sound like an interesting exercise to build.

由于JVM与Java语言密切相关，因此它执行Java规范要求的严格运行时检查.这就要求C给字节码编译器提供它们自己的松散机器抽象"，例如产生使用Java数组表示主内存的编译代码(这样指针就可以编译为整数)，并将C库链接到集中式Java类.模拟系统调用.下面列出的大多数或所有编译器都使用类似的方法.

Because of its close association with the Java language, the JVM performs the strict runtime checks mandated by the Java specification. That requires C to bytecode compilers to provide their own "lax machine abstraction", for instance producing compiled code that uses a Java array to represent main memory (so pointers can be compiled to integers), and linking the C library to a centralized Java class that emulates system calls. Most or all of the compilers listed below use a similar approach.
