* Breakpad DWARF Reader: Ignore padding at the end of the compilation unit.jimblandy2010-08-251-1/+5
| | | | | | | | | | | | | | | | | After the final DIE in a compilation unit, there may be any number of zero bytes present. This is meant to allow producers to align compilation unit starting points when necessary. This patch changes the dwarf2reader::CompilationUnit class to skip those zero bytes, rather than interpreting them as 'end of children' markers for DIEs that do not exist. Without this change, the padding bytes will cause the reader to attempt to pop an offset from an empty stack, and call EndDIE with a garbage offset. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@667 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | compute file ID At present, the Linux symbol dumper maps the ELF file into memory to examine the debugging information it contains, but then also calls google_breakpad::FileID::ElfFileIdentifier, which maps the ELF file into memory again. Some of our object files are large; Mozilla's libxul.so is 1.1GiB. Trying to map such files twice can interfere with tools like valgrind that map themselves into high addresses (in an attempt to stay out of the way of ordinary programs). The FileID class has another method, ElfFileIdentifierFromMappedFile, that operates on an already-loaded image of the file; use that instead. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@625 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | This patch avoids unnecessary use of the <cfoo> headers in files that don't actually use the identifiers they declare in the std:: namespace.

* Breakpad DWARF CFI parser: Use the proper type for offsets in ↵ted.mielczarek2010-06-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | CallFrameInfo::Rule subclasses. The subclasses of CallFrameInfo::Rule store the rule currently in force for recovering a register or computing the canonical frame address. Their sole responsibility is to accurately convey rules from the parser, which creates them, to a CallFrameInfo::Handler member function, which consumes them. So, the types of their data members should match those of the corresponding arguments of the corresponding Handler member function. CallFrameInfo::OffsetRule and CallFrameInfo::ValOffsetRule use an 'int' to store the rule's offset value, but CallFrameInfo::Handler::OffsetRule and ...::ValOffsetRule expect a 'long'. On ABIs where 'long' is larger than 'int', this can cause values to be truncated or sign-extended unexpectedly. This patch changes those members to 'long'. Fortunately, offsets appearing in real DWARF call frame information never even come close to the limits of a 32-bit int, so this bug is unlikely to cause any practical problems. A=jimb R=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@615 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Mac symbol dumper: Unify with Linux dumper; support DWARF CFI.ted.mielczarek2010-06-253-1209/+536
| | | | | | | | | | | | | | | | | | | | | | | | This patch rewrites the Mac symbol dumper to use the same set of classes the Linux dumper does for reading debugging information from various sources, consolidating them into a single table, and writing that out as a Breakpad symbol file. In the process, it also adds support for dumping DWARF call frame information and .eh_frame exception-handling information as Breakpad 'STACK CFI' records. This allows the Breakpad processor to generate stack traces from code compiled with -fomit-frame-pointer. The patch also replaces the DumpSymbols Objective C++ class with google_breakpad::DumpSymbols, a plain C++ class. The code still uses some Objective C++ to use the Foundation facilities for dealing with file names in a file-system-independent fashion, and for examining the contents of .dSYM bundles. Since the code has been entirely rewritten, I have changed the author lines. A=jimb R=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@614 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad Mac symbol dumper: Add new Mach-O reader class.ted.mielczarek2010-06-259-25/+2907
| | | | | | | | | | | | | | | | This patch adds files defining new classes in the google_breakpad::Mach_O namespace for parsing fat binaries and Mach-O files. These are used in the new dumper to handle STABS debugging information, DWARF call frame information, and .eh_frame exception handling stack walking information. These new classes are independent of endianness and word size, and therefore can be used on binaries of all the relevant architectures: x86, x86_64, ppc, and ARM. The patch adds a complete set of unit tests for the new classes.

* Breakpad Mac Dumper: Fix compilation warnings on OS X 10.6jimblandy2010-05-053-30/+80
| | | | | | | | | | | | | | | | | Breakpad's Macintosh symbol dumper uses deprecated functions for dealing with mixed-endianness code. This patch provides an overloaded function, ByteSwap, that automatically chooses the OSSwap* functions from <libkern/OSByteOrder.h> appropriate for its argument's size.

| | | | | | | | | | | | | | | | | | any time. It's possible to imagine an implementation of google_breakpad::Module in which calling SetLoadAddress at different times as the Module is populated would produce different output. For the Mac dumper, we'd like to depend on its current behavior --- that the load address is subtracted off only when writing the symbol file, and can be set at any time prior to that. This patch makes that promise part of Module's contract, and adjusts the test suite to verify that that promise is met. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@588 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Handle STABS-in-symbol-table, and line number records ↵jimblandy2010-05-054-21/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | outside functions. This patch addresses two differences between Linux and Macintosh OS X STABS data: - StabsReader assumes that the STABS entries follow the conventions for storing STABS data in object file sections (that is, .stabs and .stabstr), rather than in the object files's linker symbol table. On Mac OS X, STABS entries live in the Mach-O file's LC_SYMTAB load command, along with all the other linker symbols; they are not grouped into units by N_UNDF entries. This patch adds a boolean argument to the StabsReader constructor indicating whether the parser should treat N_UNDF entries as unit boundaries; this argument should be true on Linux, and false on Mac. The patch changes src/common/linux/dump_symbols.cc to pass this new argument. - Mac OS X STABS place SLINE (line number) records immediately before the FUN record for the function to which they belong, and the values of such records are absolute, not relative to the function start. This patch extends the parser to queue up such records and report them to the handler when we do see the FUN record. The meaning of StabsHandler::Line remains unchanged; existing handlers do not need to be adjusted. This patch also adds unit tests for the new parser behaviors. a=jimblandy, r=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@587 4c0a9323-5329-0410-9bdc-e9ce6186880e

It also adds appropriate unit tests. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@585 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Rename DumpStabsHandler to StabsToModule.jimblandy2010-05-054-34/+34
| | | | | | | | | | | | | | | All the other classes which receive debugging data from some sort of parser and use it to populate a Module have names ending in "ToModule": DwarfCUToModule, DwarfCFIToModule. Also, DumpStabsHandler doesn't actually dump anything. This patch renames the DumpStabsHandler class to StabsToModule, which is more consistent and descriptive. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@584 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Make StabsReader independent of endianness and word size.jimblandy2010-05-0511-593/+443
| | | | | | | | | | | | | | | | | | | | | | | | StabsReader simply applies a reinterpret_cast to treat the stab entry data as an array of 'struct nlist' structures, making the parser specific on the host endianness, word size, and alignment rules. On Mac OS X, a single fat binary file may contain object files of different ABIs, of which the user chooses one at run time. This patch changes the parser to read the data using the google_breakpad:: ByteCursor class, which can handle different endiannesses and word sizes. The StabsReader constructor now takes arguments indicating the endianness of the data and the size of each entry's value field. The patch changes src/common/linux/dump_symbols.cc to pass the new argument. This patch changes the StabsReader unit tests to use the google_breakpad:: TestAssembler classes to generate test data, rather than reading it from a file. This makes it easy to generate test data in various endiannesses and word sizes. It also adds tests for the new parser behaviors. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@583 4c0a9323-5329-0410-9bdc-e9ce6186880e
