If you need to read the low-level augmentation data from an FDE then you need to know whether it is there and how the FDE addresses are encoded. Which is encoded in the CIE augmentation data. > The thing is I need to get catch blocks, and eh_frame is not exactly > Dwarf format. That's why I need FDE augmentation data also. > Libdw doesn't do this, am I correct? libdw handles both .debug_frame and .eh_frame data. And you can use the Dwarf_Frames to unwind. I believe the only thing not directly exposed are the lsda and personality pointers. Is that the functionality that you need for "catch blocks"? Cheers, Mark
