* Handle frame pointer omission, (#21), part 4 (final part!): FPO stackwalker.mmentovai2006-10-201-5/+17
| | | | | | | | | | | | | r=bryner - This change allows Airbag to properly walk win32 stacks produced by code built with MSVC's frame pointer omission optimization (/Oy). This optimization is enabled at /O1 and /O2. - There too many interface and file format changes to list here. http://groups.google.com/group/airbag-dev/browse_thread/thread/85ce85bfa8457ece git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@42 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Handle frame pointer omission (#21), part 3: SourceLineResolver and ↵mmentovai2006-09-281-0/+1
| | | | | | | | | | | | | | | | | | | PDBSourceLineWriter changes. r=bryner. - PDBSourceLineWriter (dump_syms) outputs stack frame debugging information - SourceLineResolver reads the new information and puts it into a new StackFrameInfo structure, which is stored in a ContainedRangeMap. FillSourceLineInfo passes the StackFrameInfo back to the caller. - The base Stackwalker makes StackFrameInfo data available to subclasses during stackwalking, but does not use this information directly itself. Stackwalkers may access stack_frame_info_ for enhanced stackwalking (this will be part 4). - New test data for the updated dumped-symbol format http://groups.google.com/group/airbag-dev/browse_thread/thread/735f191c9a1a1de4 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@38 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Better testing for Stackwalker (#18). r=brynermmentovai2006-09-251-3/+40
| | | | | | | | | | | | | | - Test StackwalkerX86 and StackwalkerPPC on the current process, if built by a supported compiler (gcc) on a supported (walkable) CPU (x86, ppc). - This test is not enabled by default because of certain optimizations that interfere with it (stack frame reuse, frame pointer omission). See the comments at the top of stackwalker_selftest.cc. To enable this test in the standard "make check" suite, configure with --enable-selftest. http://groups.google.com/group/airbag-dev/browse_thread/thread/2ca1c8e72c809bec git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@35 4c0a9323-5329-0410-9bdc-e9ce6186880e
* ppc stackwalker (#30). r=brynermmentovai2006-09-251-2/+14
| | | | | | | | | | | | - Implementation of PowerPC stackwalker. Tested using stackwalker_selftest (#18). - Hook up processor-side multi-CPU support in MinidumpProcessor and minidump_stackwalk using the new Stackwalker::StackwalkerForCPU method. http://groups.google.com/group/airbag-dev/browse_thread/thread/1c2fa7c5182a77a9 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@34 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Handle frame pointer omission (#21), part 2: PostfixEvaluator. r=bryner.mmentovai2006-09-221-0/+21
| | | | | | | | | | | - A postfix (reverse-Polish) notation expression evaluator that we can feed stack-frame debug information into, crank, and get pointers to the calling frame from. http://groups.google.com/group/airbag-dev/browse_thread/thread/a1d6c5d1fd5fdcb9 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@32 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Handle frame pointer omission (#21), part 1: ContainedRangeMap. r=bryner.mmentovai2006-09-201-8/+32
| | | | | | | | | | | | | - ContainedRangeMap is the data structure that will be used to store and look up debugging information for frames by instruction address. The debugging information includes a way to locate the calling frame in the absence of a saved frame pointer. - Restructure RangeMap into an -inl file to match ContainedRangeMap. http://groups.google.com/group/airbag-dev/browse_thread/thread/c5823bfc1828ed42 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@29 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Make SourceLineResolver use RangeMap (#13). r=brynermmentovai2006-09-081-3/+2
| | | | | | | | | | | | | | | - Eliminate MemAddrMap from source_line_resolver.cc and adapt it to use RangeMap, also used by minidump.cc. - RangeMap operates on both a base address and a size, where MemAddrMap only used a base address, so the dumped symbol file format is modified to include size information. dump_syms produces these files and SourceLineResolver consumes them. - Provide updated test data conforming to the new dumped symbol format. http://groups.google.com/group/airbag-dev/browse_thread/thread/e9403cf3ad6336a1 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@21 4c0a9323-5329-0410-9bdc-e9ce6186880e
