* Breakpad: Add minidump processor support for DWARF Call Frame Information.jimblandy2010-03-1611-27/+1673
| | | | | | | | | | | | | | | | | | | | | | | | Add a CFIFrameInfo class (named for symmetry with WindowsFrameInfo) to represent the set of STACK CFI rules in effect at a given instruction, and apply them to a set of register values. Provide a SimpleCFIWalker class template, to allow the essential CFI code to be shared amongst the different architectures. Teach BasicSourceLineResolver to partially parse 'STACK CFI' records, and produce the set of rules in effect at a given instruction on demand, by combining the initial rule set and the appropriate rule deltas in a CFIFrameInfo object. Adapt StackwalkerX86 and StackFrameX86 to retrieve, store, and apply CFI stack walking information. Add validity flags for all the general-purpose registers to StackFrameX86::ContextValidity. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@549 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Unit tests for StackwalkerX86.jimblandy2010-03-162-0/+879
| | | | | | | | | | | | | Issue 53001 (http://breakpad.appspot.com/53001) defines the TestAssembler classes; those, along with a new set of mock classes defined in stackwalker_unittest_utils.h, make it possible for us to actually do proper unit testing of a stack walker. These tests get us full code coverage for stackwalker_x86.cc. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@548 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Processor: Add new unit tests for google_breakpad::Minidumpjimblandy2010-03-168-6/+4102
| | | | | | | | | | | | | | This also adds two new test utility class groups, TestAssembler and SynthMinidump. These are overkill for what I'm doing with them here (and may simply be overkill, period), but they make it easy to write unit tests for code that works on binary files or raw memory contents in a cross-platform way. I'm planning to use them for the DWARF CFI unwinding tests and the DWARF CFI parser tests. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@547 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad processor: Support negative literals in the postfix evaluator.jimblandy2010-02-241-4/+18
| | | | | | | | | | | | | Some versions of the libstdc++, the GNU standard C++ library, have stream extractors for unsigned integer values that permit a leading '-' sign (6.0.13); others do not (6.0.9). Regardless of the behavior of the extractors, Breakpad postfix expressions should support negative literals. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@537 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad processor: Move STACK WIN record parsing into its own function.jimblandy2010-02-051-29/+39
| | | | | | | | | | | This looks a little odd right now, since ParseStackInfo has only one alternative to handle, but I think breaking this out should make the subsequent addition of STACK CFI record support easier to review. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@514 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Give Windows stack data Windows-specific names.jimblandy2010-02-052-46/+50
| | | | | | | | | | | | | | | | | | | | | Rename BasicSourceLineResolver::Module::StackInfoTypes to WindowsFrameInfoTypes. This enum really describes the forms of Windows-specific stack unwinding data (STACK WIN records), and its name should reflect that, especially since we'll be adding support for other kinds of stack walking information. The 'stack' -> 'frame' shift matches the naming of the WindowsFrameInfo type. Similarly, rename BasicSourceLineResolver::Module::stack_info_ to windows_frame_info_. Do similar renamings in basic_source_line_resolver_unittest.cc. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@513 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Segregate STACK WIN vs. traditional stack walking.jimblandy2010-02-052-170/+246
| | | | | | | | | | | | | This patch moves the code for finding caller frames using STACK WIN data and the code to do so using the traditional frame layout (%ebp points at saved %ebp, pushed just after return address) into their own functions. In addition to making things a little clearer, this is preparation for adding support for STACK CFI records into the mix. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@512 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad x86 Stack Walker: Pass "out" parameters by address, not reference.jimblandy2010-02-052-8/+8
| | | | | | | | | | | | The Google C++ Style Guide requires all parameters passed by reference to be labeled 'const', and says that pointers should be used for output arguments. This patch brings google_breakpad::StackwalkerX86 into line. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@510 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Make PostfixEvaluator treat the MemoryRegion as const.jimblandy2010-02-053-18/+18
| | | | | | | | | | | | | | | | In order to be able to treat any MemoryRegion as const, the accessor functions need to be declared this-const, which means annotations on all the subclasses, etc. etc. Since MinidumpMemoryRegion fills its memory_ member on demand, that member needs to be marked 'mutable', but this is exactly the sort of situation the 'mutable' keyword was intended for, so that seems all right. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@509 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Save Windows unwinding data earlier in x86 walker.jimblandy2010-02-051-3/+4
| | | | | | | | | | | | | | | | | | | At the moment, StackwalkerX86::GetCallerFrame doesn't save the WindowsFrameInfo that it finds for a frame unless it successfully constructs the caller frame. This means that the windows_frame_info field of the last frame on the stack is left unset, even when that frame does have windows unwinding information. This is not user-visible behavior, so it doesn't matter, but it is a blemish on the interface, and unit tests (added in a later patch) expect it. This patch saves the information in the frame as soon as we find it. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@508 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Fix function and public symbol lookup.jimblandy2010-01-283-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In r480, I botched the change to make the comparisons that decide whether an address falls within a function's range safe from overflow. The original code said: address >= function_base && address < function_base + function_size which is fine unless the function abuts the end of the address space, in which case the addition overflows and you get a false negative. My change subtracted function_size from both sides of the latter comparison, which is meaning-preserving in true math, and gets you: address >= function_base && address - function_size < function_base This not only reads strangely, but also still overflows if function_size is greater than address. That's rare, but I've added a case to the unit tests that checks it. My intent had been to replace the addition which could overflow with a subtraction that was known not to overflow, namely: address >= function_base && address - function_base < function_size This is equivalent to the original in true math, and because of the first comparison, we know the subtraction won't underflow in MemAddr math. The patch includes similar fixes to the public symbol lookup code, and to FindWindowsFrameInfo, which was the only other function affected by r480. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@503 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Have RetrieveNearestRange correctly return range extent.jimblandy2010-01-272-2/+19
| | | | | | | | | | RangeMaps use the range's upper end as the key in the underlying map, but RetrieveNearestRange was treating the key as the lower end. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@501 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Don't pass Windows stack walking information to all walkers.jimblandy2010-01-1411-60/+36
| | | | | | | | | | | | | | | | | | | | | 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

* Issue 49013: Breakpad Processor: Use a separate API to retrieve Windows ↵jimblandy2010-01-113-74/+89
| | | | | | | | | | | | | | | | | | | | 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. This patch changes FillSourceLineInfo to do the single job its name suggests, and adds a second member function to SourceLineResolverInterface to retrieve Windows DIA stack walking information. A sibling member function will provide access to DWARF CFI stack walking data. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@480 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad: Don't use the deprecated __gnu_cxx::hash_map container.jimblandy@gmail.com2009-09-031-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
