我尝试lldb在我的Mac上运行并在启动时获取此信息:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/System/Library/PrivateFrameworks/LLDB.framework/Versions/A/Resources/Python/lldb/embedded_interpreter.py", line 1, in <module>
    import readline

我正在学习Mach-O符号化过程是如何工作的,我写了一个简单的C程序来测试一些假设.我有以下C代码:

#include <stdio.h>
#include <stdlib.h>

int division(int a, int b);

int m;

int main(void)
{
    int i,j;

    printf("initializing i\n");
    i = 10;

    printf("initializing j\n");
    j=1;

    printf("i = %d, j = %d\n", i, j);
    m = division(i, j);

    printf("m = %d / %d = %d\n", i, j, m);

    return 0;
}

int division(int a, int b)
{
    return a / b;
}

它编译使用

clang -Os -Wimplicit -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/ -arch armv7 -o helloworld helloworld.c

到以下ARM iOS程序集:
