C库在x86 / x64汇编 [英] c library x86/x64 assembler

问题描述

有用于装配在x86 / x64汇编字符串运算codeS？

Is there a C library for assembling a x86/x64 assembly string to opcodes?

例如code：

/* size_t assemble(char *string, int asm_flavor, char *out, size_t max_size); */

unsigned char bytes[32];
size_t size = assemble("xor eax, eax\n"
                       "inc eax\n"
                       "ret",
                       asm_x64, &bytes, 32);

for(int i = 0; i < size; i++) {
    printf("%02x ", bytes[i]);
}

/* Output: 31 C0 40 C3 */

我已经看过 asmpure ，但它需要在非Windows的机器上运行的修改。

I have looked at asmpure, however it needs modifications to run on non-windows machines.

我其实都需要一个汇编和反汇编，有一个库，它提供了？

I actually both need an assembler and a disassembler, is there a library which provides both?

推荐答案

当然 - 您可以使用 LLVM 。严格来说，这是C ++的，但也有是C接口。它会同时处理装配和拆卸你正在尝试做了。

Sure - you can use llvm. Strictly speaking, it's C++, but there are C interfaces. It will handle both the assembling and disassembling you're trying to do, too.
