Types table size and format in the .gcc_exception_table
As part of my research I am updating the .gcc_exception_table of a binary 64 bit elf file. For small C++ programs that throw exceptions it works OK, but for large benchmark programs it's not working. My question is does GCC stores more than one table inside the .gcc_exception_table section of the elf file. If it does what's the exact format of these tables. I have some knowledge of the action table, action records and types table. I am not clear about the size of the types table.
I am parsing the tables in this section but is not able to know the exact size and format of the types tables, where a pointer to the exception information is stored. I need to update this pointer to the new updated location.
