I was doing an incremental build for a small change, and I noticed that my compiler was working on Unified_cpp_js_src30.obj for a very very long time. I eventually assumed that I somehow hung my compiler, and I killed it. Later I realized that the cpp file I changed was unlucky enough to have been unified with the massively complex Interpreter.cpp. De-unifying Interpreter.cpp would: - Speed up recompile on the files currently unified with it - Make it more clear in Task Manager that the task is for Interpreter.obj and signal to me that I should wait longer before killing it

I approve of this change. Interpreter.cpp takes the longest to compile of any source file in the tree.

Comment on attachment 8821617 [details] [diff] [review] deunify Good observation, makes sense to me.

Perhaps the file should be renamed Intrapreter.cpp?
