Hi!
I'm learning C++ Exception Handling from the compiler point. The eh_frame
and the language-specific data area (LSDA) are generated by the compiler to
support the Exception Handling. And the eh_frame which is the dwarf2 format
applies to unwind the stack. LSDA in .gcc_except_table section applies to
record the try-catch data.
But some questions puzzled me. What differece the eh_frame & LSDA have in
differet ABIs or architectures? I searched some datum only for IA-64, but
not for other architectures(mips,etc). Are there documents for the eh_frame
and LSDA? I want to know more about these.
Thanks a lot!
Lei
