但它是针对C++程序的,它们使用eh_frame和gcc_exception_table部分来管理异常,那么为什么编译器将这些eh_frame和eh_frame_hdr部分放在程序中ELF编译C?R..*_*R.. 51 首先,最初的原因主要是政治性的 - 添加了基于DWARF的展开的人们.eh_frame希望它成为一个始终存在的功能,因此它可以用于实现除C++异常之外的各种...
二、objdump .eh_frame section 2.1 objdump -s 2.2 objdump --dwarf=frames 2.3 objdump --dwarf=frames-interp 参考资料 前言 这篇文章介绍了Linux .eh_frame section:Linux .eh_frame section以及libunwind 程序在编译期间通过插入 cfi 指令的方式记录,cfi 指令最终会生成可执行 elf 文件中的 .eh_frame 段。
When gcc generates code that handles exceptions, it produces tables that describe how to unwind the stack. These tables are found in the .eh_frame section. The format of the .eh_frame section is very similar to the format of a DWARF .debug_frame section. Unfortunately, it is not precisely...

The DWARF specification requires the CIE/FDE entries in the .eh_frame sections to be aligned to pointer size. However, I incorrectly implemented it as the platform target pointer size, while it's supposed to be the DWARF pointer size specified in the pointer encoding field. Since we use 4-...
