[llvm-commits] [llvm] r65039 - in /llvm/trunk: include/llvm/CodeGen/DebugLoc.h utils/TableGen/AsmWriterEmitter.cpp

[Bill Wendling]

Author: void
Date: Thu Feb 19 03:16:38 2009
New Revision: 65039

URL: http://llvm.org/viewvc/llvm-project?rev=65039&view=rev
Log:
Print out a new label only if the debug location *tuple* is different. The debug
locations may change, but the tuples may be the same.
