clayborg added a comment. BTW: if we can modify clang to produce the Apple accelerator tables, we won't need to do any of this indexing which will really speed up debugging! We only produce the Apple accelerator tables on Darwin, but we could on other systems. There is also a new version of the accelerator tables that is going to be in DWARF 5 that is a modified version of our Apple accelerator tables. The Apple accelerator tables are actual accelerator tables that can be mmap'ed in and used as is. All other DWARF accelerator tables are actually not accelerator tables, they are randomly ordered tables that need to be sorted and ingested and often don't contain the correct things that a debugger wants. Like ".debug_pubtypes" will only mention "public" types. Any private types are not in the table. So the table is useless. Same goes for "debug_pubnames": only "public" names... Useless. So our new accelerator tables actually have all of the data in a format that can be used as is, no extra sorting required. They really speed up debugging and stop us from having to index the DWARF manually.
