* Breakpad: Support DWARF CFI-driven stack walking on ARM.jimblandy2010-03-161-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Update copyright notice years on all files changed in 2010.jimblandy2010-02-091-1/+1
| | | | | | | | | | We've gotten mixed advice from the lawyery types about whether this matters. But it's easy enough to do. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@517 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Don't pass Windows stack walking information to all walkers.jimblandy2010-01-141-3/+1
| | | | | | | | | | | | | | | | | | | | | 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 49012: Breakpad Processor: Rename 'StackFrameInfo' structure to ↵jimblandy2009-12-231-1/+1
| | | | | | | | | | | | | | | 'WindowsFrameInfo'. Also, rename stack_frame_info.h to windows_frame_info.h. If it seems odd to have functions like FillSourceLineInfo returning Windows-specific data structures... well, it is! This patch just makes it more obvious what's going on. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@471 4c0a9323-5329-0410-9bdc-e9ce6186880e
