* Breakpad processor: Support AMD64 stack unwinding driven by DWARF CFI.jimblandy2010-03-164-41/+462
| | | | | | | | | | | 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.jimblandy2010-03-164-15/+584
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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

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.

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
