URL: http://llvm.org/viewvc/llvm-project?rev=291446&view=rev
Log:
[include-fixer] Load symbol index asynchronously.
We don't actually need the index until parse time, so fetch it in the
background and start parsing. By the time it is actually needed it's
likely that the loading phase has completed in the background.
