* Mac dump_syms: accept __DWARF segment without __debug_info sectionMark Mentovai2019-08-071-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | A .dSYM may validly contain a __DWARF segment without any __debug_info section. This can occur for Chromium Framework in a component build of Chromium, because in that case, all of the code is in other libraries that Chromium Framework depends on. This was previously tested by an assertion, but the assertion did not trigger in NDEBUG (release) builds. In NDEBUG builds, this condition would lead to an out-of-bounds read, detected by AddressSanitizer. Instead of an assertion, the check is now always done at runtime. Instead of being fatal, it's now just a warning, because it's been established that __DWARF without __debug_info can occur. (In the Chromium case, it remains pointless to run dump_syms via the "chrome_dump_syms" target on a component build, as it'll only attempt to symbolize Chromium Framework, and not any of the libraries that Chromium Framework depends on that actually contain the code.)

* Add support for parsing the DW_AT_ranges attributesGabriele Svelto2018-08-131-0/+1
| | | | | | | | | | | | | | | | This enables the DWARF reader to properly parse DW_AT_ranges attributes in compilation units and functions. Code covered by a function is now represented by a vector of ranges instead of a single contiguous range and DW_AT_ranges entries are used to populate it. All the code and tests that assumed functions to be contiguous entities has been updated to reflect the change. DW_AT_ranges attributes found in compilation units are parsed but no data is generated for them as it is not currently needed.

* Added an option (-i) to have dump_syms output header information only.David Yen2016-04-081-0/+9
| | | | | | | | | | | | | | | | | It is often helpful to check if a particular symbol file dumped by dump_syms actually matches a version of a binary file we have. The symbol output contains an ID which can be used to see if it matches the binary file. Unfortunately, this ID is internally calculated and not a standard hash of the binary file. Being able to output the header information only will allow users to determine whether their symbol file is up to date or not.

* Fix Mac Breakpad host tools to build in Linux cross-compileTed Mielczarek2015-09-161-12/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're working on building our Firefox Mac builds as a Linux cross-compile (https://bugzilla.mozilla.org/show_bug.cgi?id=921040) and we need symbol dumping to work. This change ports the Mac dump_syms tool to build and work on Linux. I've tested it and it produces identical output to running the tool on Mac. The bulk of the work here was converting src/common/mac/dump_syms.mm and src/tools/mac/dump_syms/dump_syms_tool.mm from ObjC++ to C++ and removing their use of Foundation classes in favor of standard C/C++. This won't compile out-of-the-box on Linux, it requires some Mac system headers that are not included in this patch. I have those tentatively in a separate patch to land in Gecko (http://hg.mozilla.org/users/tmielczarek_mozilla.com/mc/rev/5fb8da23c83c), but I wasn't sure if you'd be interested in having them in the Breakpad tree. We could almost certainly pare down the set of headers included there, I didn't spend too much time trying to minimize them (we primarily just need the Mach-O structs and a few associated bits). I just realized that this patch is missing updating the XCode project files (ugh). I'll fix that up in a bit.

* Breakpad Mac symbol dumper: Unify with Linux dumper; support DWARF CFI.ted.mielczarek2010-06-251-49/+131
| | | | | | | | | | | | | | | | | | | | | | | | This patch rewrites the Mac symbol dumper to use the same set of classes the Linux dumper does for reading debugging information from various sources, consolidating them into a single table, and writing that out as a Breakpad symbol file. In the process, it also adds support for dumping DWARF call frame information and .eh_frame exception-handling information as Breakpad 'STACK CFI' records. This allows the Breakpad processor to generate stack traces from code compiled with -fomit-frame-pointer. The patch also replaces the DumpSymbols Objective C++ class with google_breakpad::DumpSymbols, a plain C++ class. The code still uses some Objective C++ to use the Foundation facilities for dealing with file names in a file-system-independent fashion, and for examining the contents of .dSYM bundles. Since the code has been entirely rewritten, I have changed the author lines. A=jimb R=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@614 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad: Don't use the deprecated __gnu_cxx::hash_map container.jimblandy@gmail.com2009-09-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Modern GNU compilers warn about the #inclusion of <ext/hash_map>; that container is deprecated, and code should use <tr1/unordered_map> instead. However, to stay within the boundaries of C++ '98, it's probably fine just to use plain old std::map. Breakpad uses hash_map in three cases: o The DWARF reader's SectionMap type maps object file section names to data. This map is consulted once per section kind per DWARF compilation unit; it is not performance-critical. o The Mac dump_syms tool uses it to map machine architectures to section maps in Universal binaries. It's hard to imagine there ever being more than two entries in such a map. o The processor's BasicSourceLineResolver uses a hash_map to map file numbers to file names. This is the map that will probably have the most entries, but it's only accessed once per frame, after we've found the frame's line entry. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@393 4c0a9323-5329-0410-9bdc-e9ce6186880e
