annotate gen/optimizer.cpp @ 984:4c0df37d0421
Removing ldc.conf. (IMPORTANT: run 'cmake .' after pull)
Added it to .hgignore.
This gets rid of spurious differences caused by CMake regenerating it differently.
Just run 'cmake .' to get it back in your local checkout.

Fixed the optimizer thing, since llvm PR 2800 is already fixed, users need to upgrade LLVM to latest svn.
