Description Jesse Ruderman 2009-06-26 08:01:14 UTC 
Would it be sensible to make --auto-run-dsymutil=yes only take the time to read symbols if a tool needs the symbols, e.g. to output an error?  That way, if there are no errors in a given library, the app would start up a little faster.

It would also make missing entries in the is_systemish_library check less likely to cause problems.
Comment 2 Nicholas Nethercote 2009-07-15 00:16:04 UTC 
While we're at it, we could make all debug info reading lazy.  Instead of reading all debug symbols (and possibly runnying dsymutil, on Darwin) when code is loaded, attach a flag to the code indicating if its debug info has been loaded, and check that before doing any debug info lookups.  This might make a significant speed difference on really large programs.
