This patch allows Breakpad's DWARF reader to at least read or skip attributes using the new forms defined in version 4 of the DWARF specification, instead of crashing. Attributes encoded using DW_FORM_flag_present, DW_FORM_sec_offset, and DW_FORM_exprloc should work fine now. However, compilation units using DW_FORM_ref_sig8 to refer to types in .debug_types will need further work to support. (GCC 4.6.2 does not emit .debug_types sections.) Specifically: - dwarf2reader::DwarfForm gets new values. - dwarf2reader::Dwarf2Handler and dwarf2reader::DIEHandler get new handler methods, named ProcessAttributeSignature, for DW_FORM_ref_sig8 attributes. - dwarf2reader::CompilationUnit reads DW_FORM_ref_sig8 attributes, and passes them to ProcessAttributeSignature. It also gets support for DW_FORM_sec_offset, DW_FORM_exprloc, and DW_FORM_flag_present, using the existing appropriate ProcessAttribute* methods. - dwarf2reader::DIEDispatcher passes through ProcessAttributeSignature attributes to its DIEHandler. - Unit tests are updated. |
