[lldb-dev] Compilation on Linux

The LLDB sources currently compile with the following revision:

--revision {2010-08-02T16:00}

If you check those source out, it will take all of the llvm/clang changes out of the challenge for building on llvm. Currently if you always want to know which revision the sources are locked down to, you can check the "lldb/scripts/build-llvm.pl" file around line 28:

our $llvm_revision = "'{2010-08-02T16:00}'";

We tend not to keep up with all of the changes going into clang on a day to day basis right now, sorry for that.

The function header contains a FIXME that suggests delegation to the DynamicLoader plugin - Can I assume that as that plugin is now available the UpdateLoadedSections function is now deprecated and can be removed?
