* Add optional field indicating multiple symbols at an addressMike Wittman2017-11-292-59/+93
| | | | | | | | | | | | | | | | | | Adds an optional 'm' as the first field in FUNCTION and PUBLIC records to indicate that the address corresponds to more than one symbol. Controls this by a command line flag for now to give symbol file users a chance to update. Also reduces the number of IDiaSymbols retained in memory to one per address. This reduces memory consumption by 8% when processing chrome.dll.pdb. Updates the processor to parse the new optional field.

* android: Don’t compete with NDK API >= 21 over NDK structuresMark Mentovai2017-09-182-39/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chrome uses API 16 for 32-bit builds and API 21 for 64-bit builds. The NDK’s <link.h> provides r_debug and link_map structure definitions only at API 21 and above. Breakpad used a custom <link.h> to define these structures only during 64-bit builds, which worked for Chrome’s purposes. However, other consumers may wish to build Breakpad at arbitrary API levels without regard to bitness. This alters Breakpad’s custom <link.h> to correctly check the NDK API level rather than target CPU bitness. Likewise for <sys/user.h> on 32-bit x86, which provided a typedef for user_fpxregs_struct to user_fxsr_struct. API 21 and above, as well as the unified headers at any API level, always name the structure user_fpxregs_struct. Definitions for 64-bit ARM’s user_regs_struct and user_fpsimd_struct have been removed from Breakpad’s copy of <sys/user.h>. The header claims that these fallback definitions are only necessary with NDK r10, which should no longer be in use even by Chromium, which now uses NDK r12b. This removes the Chromium-specific ANDROID_NDK_MAJOR_VERSION macro from use entirely. Fixes https://stackoverflow.com/questions/44141159/ and b/65630828.

* Parse DWARF 4 line tables correctlyMark Mentovai2017-09-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Breakpad’s DWARF line table reader only understood line tables at the level of DWARF 2. This wasn’t a problem because LLVM only produced line tables at this level, even when generating DWARF 4. But LLVM would like to output DWARF 4 line tables when generating DWARF 4, and Breakpad needs to understand this format. (Meanwhile, it seems that GCC has used DWARF 4 line tables with DWARF 4 output since 4.5.0, 2010-04-14.) DWARF 3 line tables are fully compatible with DWARF 2 (assuming that nothing needs “prologue end,” “epilogue begin,” or “isa”, and opcodes related to these fields are properly skipped). DWARF 4 changes the line number program header slightly to include a “maximum operations per instruction” field. This field must be recognized, but can safely be ignored (and assumed to be always 1) if VLIW architectures are not supported (they aren’t). DWARF 4 also introduces a “discriminator”, whose opcode can also be skipped if these values are not needed (they shouldn’t be). This recognizes the “maximum operations per instruction” field when processing DWARF 4 line tables, but asserts that its value is 1 and otherwise ignores it. This is not compatible with VLIW architectures that set this field to a value other than 1. Such architectures are irrelevant to Breakpad, and mainline GCC and the proposed LLVM patch always set this field to 1. There are other things that could be extracted from DWARF 3 and 4 line tables that aren’t currently extracted (although these are currently irrelevant to Breakpad too).

* Handle ntdll only emitting PUBLIC at func entryScott Graham2017-02-233-1/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This handles a case encountered in ntdll.dll symbols for Windows 7, where a PUBLIC would be emitted only for the entry point to the function. The body of the function, however, is split in a PGO-ish fashion to another remote location in the binary. Because of this, there were large gaps in the RVA space that would be attributed to the "last" function that happened to have an entry point before the gap. In practice, something like this: 0x100 Func1 0x110 Func2 0x120 Func3 0x130 Func4 ... 0x800 LaterFuncs The bodies of Func1/2/3 tend to be implemented as a fast-path check, followed by a jmp to somewhere in the range between 0x130 and 0x800. Because no symbols are emitted for this range, everything is attributed to Func4, causing crash misattribution. In this CL, the change is: after emitting the entry point symbol, also walk in the original OMAP entries through the untranslated binary, and for each block until we resolve to a new symbol (via the same mechanism as we found the entry point) emit another PUBLIC indicating that there's another block that belongs to that symbol. This effectively breaks up the "0x130 - 0x800" range above.

| | | | | | | | | | | | | | | | | The Rust compiler uses GCC C++ name mangling, but it has another layer of encoding so abi::cxa_demangle doesn't produce great results. This patch changes dump_syms to dump unmangled names by default so that consumers can demangle them after-the-fact. It also adds a tiny bit of support for linking against a Rust library I wrote that can demangle Rust symbols nicely: https://github.com/luser/rust-demangle-capi BUG= Change-Id: I63a425035ebb7ac516f067fed2aa782849ea9604 Reviewed-on: https://chromium-review.googlesource.com/402308 Reviewed-by: Mark Mentovai <mark@chromium.org>

* Initial support for dumping DWARF corresponding to Swift codeMark Mentovai2016-09-236-33/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | The DWARF data for Swift code has a top-level DW_TAG_module DIE as the child of the DW_TAG_compile_unit DIE and the parent of the DW_TAG_subprogram DIEs that dump_syms uses to locate functions. dump_syms needs to process DW_TAG_module DIEs as introducing nested scopes to make it work with Swift. This also reworks demangling to be language-specific, so that the C++ demangler isn't invoked when processing Swift code. The DWARF data for Swift code presents its mangled names in the same form as used for C++ (DW_AT_MIPS_linkage_name or DW_AT_linkage_name) but the mangling is Swift-specific (beginning with _T instead of _Z). There is no programmatic interface to a Swift name demangler as an analogue to C++'s __cxa_demangle(), so mangled Swift names are exposed as-is. Xcode's "xcrun swift-demangle" can be used to post-process these mangled Swift names on macOS. Support for mangled names presented in a DW_AT_linkage_name attribute, as used by DWARF 4, is added. This supersedes the earlier use of DW_AT_MIPS_linkage_name. BUG=google-breakpad:702,google-breakpad:715 R=ted.mielczarek@gmail.com Review URL: https://codereview.chromium.org/2147523005 .
