[PATCH] D96035: [dsymutil][DWARFlinker] implement separate multi-thread processing for compile units.

[Greg Clayton via Phabricator via llvm-commits]

clayborg added a comment.

One issue I do see with this approach as well is the first "__type_table" is about 69MB for a dSYM file for LLDB.framework in LLDB. Any types that are accessed from debug info in LLDB will end up causing this entire DW_TAG_compile_unit to be parsed which can be expensive as LLDB parses DWARF partially and only parses what it needs to when loading DWARF. Is there any way to split up the "__type_table" into multiple DW_TAG_compile_unit entries whose DW_AT_name matches the DW_AT_decl_file of the root type that is being uniqued? That would allow smaller compile units to be parsed and keep memory footprint down in debuggers.
