[llvm-commits] [llvm] r83510 - /llvm/trunk/lib/Transforms/Scalar/InstructionCombining.cpp

New Revision: 83510

URL: http://llvm.org/viewvc/llvm-project?rev=83510&view=rev
Log:
In instcombine's debug output, avoid printing ADD for instructions that are
already on the worklist, and print Visited when an instruction is about to be
visited.  Net, on one input, this reduced the output size by at least 9x.
