Jakob Stoklund Olesen 2c5a960b0e Clarify that duplicate edges are not allowed in the Machine CFG. ... LLVM IR has labeled duplicate CFG edges, but since Machine CFG edges don't have labels, it doesn't make sense to allow duplicates. There is no way of telling what the edges mean. Duplicate CFG edges cause confusion when dealing with edge weights. It seems that code producing duplicate CFG edges usually does the wrong thing with edge weights. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162227 91177308-0d34-0410-b5e6-96231b3b80d8		2012-08-20 21:05:58 +00:00
