New Revision: 101326
URL: http://llvm.org/viewvc/llvm-project?rev=101326&view=rev
Log:
Add optional timing logging for code completion results. This causes a UDP packet
containing the time taken for the code completion to be sent to a designated server
(which is specified using a compile-time -D flag).
