New Revision: 38158

URL: http://llvm.org/viewvc/llvm-project?rev=38158&view=rev
Log:
Add a builder for processing @name@ style configuration replacements. This
allows files like hlvm/Base/Config.h.in to be turned into Config.h, substituting
configuration values for the various substitution tokens.
