* Breakpad processor: Support AMD64 stack unwinding driven by DWARF CFI.jimblandy2010-03-161-14/+30
| | | | | | | | | | | This adds support for 'STACK CFI' records (DWARF CFI) to the AMD64 stack walker. This is necessary for the stack trace to include any frames other than the youngest. Unit tests are included. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@554 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad: Support DWARF CFI-driven stack walking on ARM.jimblandy2010-03-161-11/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the Breakpad minidump processor to use data from STACK CFI records to generate stack traces for the ARM processor. In the symbol dumper, we need a table mapping DWARF CFI register numbers to their names: STACK CFI records refer to registers by name. In the processor, we expand StackwalkerARM::GetCallerFrame to see if there are STACK CFI records covering the callee, and then use those to recover the caller's register values. There's no good reason the ARM walker couldn't use the SimpleCFIWalker interface declared in cfi_frame_info.h. Unfortunately, that interface assumes that one can map register names to member pointers of the raw context type, while MDRawContextARM uses an array to hold the registers' values: C++ pointer-to-member types can't refer to elements of member arrays. So we have to write out SimpleCFIWalker::FindCallerRegisters in StackwalkerARM::GetCallerFrame. We define enum MDARMRegisterNumbers in minidump_cpu_arm.h, for convenience in referring to certain ARM registers with dedicated purposes, like the stack pointer and the PC. We define validity flags in StackFrameARM for all the registers, since CFI could theoretically recover any of them. In the same vein, we expand minidump_stackwalk.cc to print the values of all valid callee-saves registers in the context --- and use the proper names for special-purpose registers. We provide unit tests that give full code and branch coverage (with minor exceptions). We add a testing interface to StackwalkerARM that allows us to create context frames that lack some register values. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@553 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad: Add minidump processor support for DWARF Call Frame Information.jimblandy2010-03-163-12/+28
| | | | | | | | | | | | | | | | | | | | | | | | 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: Make PostfixEvaluator treat the MemoryRegion as const.jimblandy2010-02-052-17/+17
| | | | | | | | | | | | | | | | 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: Don't pass Windows stack walking information to all walkers.jimblandy2010-01-142-9/+15
| | | | | | | | | | | | | | | | | | | | | 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 ↵jimblandy2010-01-112-8/+14
| | | | | | | | | | | | | | | | | | | | 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.com2009-09-031-24/+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
