The right way to do this it to add the DW_AT_linkage_name to the class. Apple accelerator tables have many different forms, but one is a mapping of type name to exact DIE offset (in the __DWARF_ segment in the __apple_types section). If the mangled name was added to the class, then the apple accelerator tables would have it. So when a lookup happens with these tables around, we do a very quick hash lookup, and we find the exact DIE (or DIEs) we need. Entries for classes in the Apple accelerator tables have both the mangled and raw class name as entries pointing to the same DIE since lookups don't usually happen via mangled names. LLDB also knows how to pull names apart and search correctly, so if someone tries to lookup a type with "a::b::MyClass", we will chop that up into "MyClass" and do a lookup on that. We might get many many different "MyClass" results back (a::c::MyClass, ::MyClass, b::MyClass), but then we cull those down by making sure any matches have a matching decl context of "a::b::". For mangled names, it is easy and just a direct lookup.<br class=""><br class="">The apple accelerator tables are only enabled for Darwin target, but there is nothing to say we couldn't enable these for other targets in ELF files. It would be a quick way to gauge the performance improvement that these accelerator tables provide for linux. Currently linux will completely index the DWARF, but it will load the DWARF, index it, and unload the DWARF so we don't hog memory for things we don't need loaded yet. We must manually index the DWARF because the DWARF accelerator tables are really not accelerator tables, they are random indexes of related data (names in no particular order, addresses in or particular order). These tables are also not complete so no debugger can rely on them. For example ".debug_pubtypes" is for "public" types only. ".debug_pubnames" is a random name table with only public functions (no static functions or functions in anonymous namespaces). So the DWARF accelerator tables can't be used by debuggers.<br class=""><br class="">There is now a modified version of the Apple accelerator tables in the DWARF standard that can provide the same data as the Apple versions, but I don't believe anyone has added this support to any compilers yet. So for simplicity, we can try things out with the Apple accelerator tables and see how things go.<br class=""><br class="">Another solution involves using llvm-dsymutil, a DWARF linker that is used on Apple platforms. It is a tool that is normally run on executables where the DWARF is left in the .o files and linked later into final DWARF files. This tool also has a "--update" option that take a linked dSYM file and updates the accelerator tables in case they change over time, or in case an older version of llvm-dsymutil didn't add everything that was needed to the tables due to a bug. So another way we can try this out is to modify the llvm-dsymutil to work with ELF files and have it generate and add the Apple accelerator tables to the ELF files. This is nice because it allows us to use DWARF that is generated by any compiler (no need for the compiler to support making the accelerator tables). This would a great way to try out the accelerator tables without requiring compiler changes.<br class=""><br class="">The short term solution is to validate that the Apple accelerator tables work and do speed debugging up by a large amount. The long term solution is to have clang start emitting the new DWARF accelerator tables and modify LLDB to support and use those tables.<br class=""><br class="">Let me know if there are any questions on any of this.<br class=""><br class="">Greg Clayton<br class=""><br class=""><blockquote type="cite" class="">On Dec 19, 2017, at 5:35 AM, Tamas Berghammer via lldb-dev <<a href="mailto:lldb-dev@lists.llvm.org" class="">lldb-dev@lists.llvm.org</a><span class="Apple-converted-space"> </span><<a href="mailto:lldb-dev@lists.llvm.org" class="">mailto:lldb-dev@lists.llvm.org</a>>> wrote:<br class=""><br class="">Hi,<br class=""><br class="">I thought most compiler still emits DW_AT_MIPS_linkage_name instead of the standard DW_AT_linkage_name but I agree that if we can we should use the standard one.<br class=""><br class="">Regarding performance we have 2 different scenarios.
