* Breakpad Mac symbol dumper: Add new Mach-O reader class.ted.mielczarek2010-06-251-3/+3
| | | | | | | | | | | | | | | | This patch adds files defining new classes in the google_breakpad::Mach_O namespace for parsing fat binaries and Mach-O files. These are used in the new dumper to handle STABS debugging information, DWARF call frame information, and .eh_frame exception handling stack walking information. These new classes are independent of endianness and word size, and therefore can be used on binaries of all the relevant architectures: x86, x86_64, ppc, and ARM. The patch adds a complete set of unit tests for the new classes.

* Breakpad test support: Move test_assembler.{h,cc} from src/processor to ↵jimblandy2010-04-271-1/+1
| | | | | | | | | | | | | | src/common. The google_breakpad::TestAssembler classes are used in both the processor's and the Linux dumper's test suites, and will soon be used in the Mac dumper's tests as well. This patch moves their source files from src/processor to src/common. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@574 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Parse the .eh_frame section.jimblandy2010-03-161-4/+111
| | | | | | | | | | | | | | | | | | | | | | | | Extend google_breakpad::CFISection with the ability to produce .eh_frame data. Entry headers have a different format, and pointers can be encoded in new and fascinating ways. Extend dwarf2reader::CallFrameInfo to be able to parse either DWARF CFI or .eh_frame data, as determined by an argument to the constructor. Cope with variations in header formats, encoded pointers, and additional data in 'z' augmentation data blocks. Extend the unit tests appropriately. Extend dump_syms to look for a .eh_frame section, and if it is present, find the necessary base addresess and parse its contents. There's no need for DwarfCFIToModule to check the version numbers; if CallFrameInfo can parse it, DwarfCFIToModule should be able to handle it. Adjust tests accordingly. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@552 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Add support for dumping DWARF CFI as STACK CFI records.jimblandy2010-03-161-0/+149
Define a new DWARF parser class, dwarf2reader::CallFrameInfo. Extend google_breakpad::Module to store and write out 'STACK CFI' records. Define a new google_breakpad::DwarfCFIToModule class, to accept DWARF CFI data from the parser and populate a Module with the equivalent STACK CFI records. Extend the Linux symbol dumping tool, dump_syms, to use dwarf2reader::CallFrameInfo, google_breakpad::DwarfCFIToModule, and google_breakpad::Module to extract DWARF CFI from the executable or shared library files and write it to the Breakpad symbol file. Define CFISection, a new class derived from TestAssembler::Section, for use in creating DWARF CFI data for test cases. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@550 4c0a9323-5329-0410-9bdc-e9ce6186880e
