* Don't demangle Rust symbols by default, but allow linking to rust-demangle.Ted Mielczarek2016-10-251-0/+1
| | | | | | | | | | | | | | | | | 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 Mentovai2016-09-231-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 .

* Breakpad symbol dumper: Move Linux dumping classes into src/common.jimblandy2010-04-051-0/+84
The Linux symbol dumper's classes are reasonably portable, and should be usable for the Mac dumper as well. Move them to src/common, along with their unit tests. Update #include directives and Makefile. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@567 4c0a9323-5329-0410-9bdc-e9ce6186880e
