[lldb-dev] Problem with large sym files

[Somorjai, Akos]

Hello everyone,

I've just recently started to convert our codebase to LLVM 3.0, and also gave a try to debugging with LLDB. And that's where I ran into a serious wall: lldb is unable to load the sym files for our main executable (not to mention the numerous shared libraries it uses). I'm using LLDB-75 on Mac OS X 10.6.8 on a Core i7 MacBook Pro, have 8 GB memory, the sym format is DWARF-2.

Well, it loads the sym files after 15 mins or so, but then setting a breakpoint also took 10 mins, and step one line during debugging is another 15 mins.

At the end of the process Xcode used 35 GBs of virtual and 6.5 GBs of real memory (according to the Activity Monitor).

Is there anything I can do about it?

GDB handles this situation quite gracefully…

Thanks,
