* Breakpad Linux Dumper: Add DWARF support.jimblandy2010-01-2311-28/+3996
| | | | | | | | | | | | | | | | | | | | | | | | This adds DWARF support to the Breakpad Linux dumper. This is implemented as two handler classes: google_breakpad::DwarfCUToModule accepts data from dwarf2reader::CompilationUnit, and google_breakpad::DwarfLineToModule accepts data from a dwarf2reader::LineInfo, each populating a google_breakpad::Module with the results. Behaviors specific to particular source languages are handled by instances of a new class, google_breakpad::Language. An input executable may contain both STABS and DWARF debugging information: the dumper automatically recognizes what sorts of information are available, and integrates the data into a single output file. All classes have unit tests, providing line and branch coverage of all interesting code. Unit tests are written using the Google C++ Testing Framework, and the Google C++ Mocking Framework where appropriate. a=jimblandy, r=ccoutant git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@497 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad DWARF Parser: Improved DWARF-processing interface.jimblandy2010-01-234-0/+1106
| | | | | | | | | | | | | | | | | | dwarf2reader::CompilationUnit is a simple and direct parser for DWARF data, but its handler interface is not convenient to use. In particular, the same handler object receives data about all DIEs processed. One can't use distinct classes to separate the information needed to handle different kinds of data. This patch defines a new adapter type, dwarf2reader::DIEHandler, which implements the existing DWARF parser's handler interface, given a handler written to a more comfortable, object-orient interface. The comments in dwarf2diehandler.h provide more detail. a=jimblandy, r=ccoutant git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@495 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad DWARF Reader: Change LineInfoHandler::AddLine to provide the line's ↵jimblandy2010-01-224-28/+50
| | | | | | | | | | | | | | | | | | | | length. Breakpad's DWARF line number info parser provides a code address, file, and line number for each code/source pairing, but doesn't provide the length of the machine code. This makes that change, as discussed in the following thread: http://groups.google.com/group/google-breakpad-dev/browse_thread/thread/ed8d2fde79319368p This patch also makes the corresponding changes to the functioninfo.cc module, used by the Mac dumper. This patch has no effect on the Mac dumper's output. a=jimblandy, r=ccoutant git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@494 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad DWARF Reader: Also look for DWARF in sections with the proper names.jimblandy2010-01-221-6/+18
| | | | | | | | | | | | The DWARF specification specifices which names the sections containing DWARF information should have. OSX uses slightly different names. This patch changes the DWARF reader to look for the sections under both sets of names. a=jimblandy, r=ccoutant git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@493 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad processor: Don't pass Windows stack walking information to all walkers.jimblandy2010-01-1413-69/+51
| | | | | | | | | | | | | | | | | | | | | At the moment, the StackWalker GetCallerFrame member function expects a vector of WindowsFrameInfo structures, even though WindowsFrameInfo is only used or useful on one one implementation (StackWalkerX86). This patch changes StackWalker::GetCallerFrame to no longer expect the WindowsFrameInfo structures, and changes all implementations to match. In particular, StackWalkerX86 is changed to find the WindowsFrameInfo data itself, and store a pointer to whatever it got in the StackFrame object itself (which is really a StackFrameX86). To allow GetCallerFrame implementations to look up stack walking data, StackWalker::resolver_ needs to be made protected, not private. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@491 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: STABS reader incorrectly assumes a single compilation ↵jimblandy2010-01-143-35/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | unit The stabs reading code in google-breakpad incorrectly assumes that the stabs data is a single compilation unit. Specifically, it ignores N_UNDF stabs and assumes that all string indices are relative to the beginning of the .stabstr section. This is true when linking with the GNU linker by default, because the GNU linker optimizes stabs debug info. The gold linker does not do this optimization. It can be disabled when using the GNU linker with the --traditional-format command line option. For more details of the problem, see: http://sourceware.org/bugzilla/show_bug.cgi?id=10338 http://code.google.com/p/google-breakpad/issues/detail?id=359 This patch adds unit tests that reproduce the failure, and fixes the stabs parser. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@490 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Google Breakpad DWARF reader: Add a handler function for DIE references.jimblandy2010-01-124-31/+70
| | | | | | | | | | | | | | | Add a new member function to dwarf2reader::Dwarf2Handler, ProcessAttributeReference, for reporting attribute values that are references to other DIEs.

| | | | | | | | | | | | | | | | | | | | stack debugging info. At the moment, FillSourceLineInfo returns Windows DIA-based stack walking data. In addition to being ugly, this makes it difficult to provide access to DWARF CFI-based stack walking data in a symmetrical way.

| | | | | | | | | | | | | | | | | | | | | | | Fix typos. For CompilationUnit::Start, I was confused by the '-' in the original comment, taking it for a parenthetic clause marker, assuming an implicit "of the next compilation unit" at the end of the sentence. The comments should refer to the ".debug_info" section, not the "debug_info" section. The latter is not the section name actually used on any system (ELF or Mach-O), and the former is the name prescribed by the DWARF spec. Some of the comments for ProcessAttribute* member functions claim that OFFSET is from the start of the compilation unit, but that's not so: the code has always passed an offset relative to the start of the .debug_info section. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@453 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | | It seems that a use of the <stdint.h> type uintptr_t has crept into the DWARF parser. This defines a workaround for the GNU compilers (tested on both Mac and Linux) which will raise an error if it doesn't work. My personal preference would be just to assume that the <stdint.h> header is available and use the standard types everywhere, but 1) that would be a large change, likely to make merges with the other branches of the DWARF parser more difficult, and 2) it would make it quite difficult to build under Microsoft Visual Studio, which doesn't have the <stdint.h> header; Microsoft has said they have no plans to provide it, as they would rather "focus their efforts" on C++ and .NET. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@448 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | | | The test system is based on Google C++ Testing Framework and the Google C++ Mocking Framework. This includes a parser that turns human-readable input files ("mock stabs") into .stab and .stabstr section contents, which we can then pass to a StabsReader instance, using a handler object written with GoogleMock. The 'make check' target in src/tools/linux/dump_syms runs this. The supplied input file is pretty small, but I've done coverage testing, and it does cover the parser. I thought the mock stabs parser would be less elaborate than it turned out to be.

* Issue 39001: Breakpad Linux dumper: Refactor Makefile.jimblandy@gmail.com2009-12-151-24/+123
| | | | | | | | | | | | | | | | | | Use GNU Make features to make the dumper, unit tests, and maintenance targets more independent, so I get fewer conflicts as I work on different parts of the patch series. In particular: - Provide targets to run tests and produce test coverage reports. - Gather C and C++ build rules in one place. - Avoid variables that list object files, as pattern rules can compute these values directly from the dependencies. - Use VPATH to find sources in other directories. a=jimb, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@441 4c0a9323-5329-0410-9bdc-e9ce6186880e
