老师你好,x86_64平台 API:30
libsample反汇编
126c: e8 4f fa ff ff callq cc0 tgkill@plt
1271: bf 04 00 00 00 mov $0x4,%edi
CFI方式:
I/xunwind_tag: #1 pc 0000000000001270 /data/app/~~WZ_mVkK4mGpxxUIdnHz4Mg==/io.hexhacking.xunwind.sample-B_YKIacqKu-eUUOxomuhFQ==/lib/x86_64/libsample.so
与实际调用栈偏移4个字节。
EH方式:
I/xunwind_tag: #5 pc 0000000000001271 /data/app/~~WZ_mVkK4mGpxxUIdnHz4Mg==/io.hexhacking.xunwind.sample-B_YKIacqKu-eUUOxomuhFQ==/lib/x86_64/libsample.so
与实际调用栈偏移5个字节。
这是怎么回事呢?
我想做一个自动化的转换工具,该怎么兼容呢?
