New Revision: 116250
URL: http://llvm.org/viewvc/llvm-project?rev=116250&view=rev
Log:
Eliminate -fdiagnostics-binary and all of the infrastructure for
emitting diagnostics in a binary form to be consumed by libclang,
since libclang no longer does any of its work out-of-process, making
this code dead. Besides, this stuff never worked at 100% anyway.
