Scott Michel 327d0651f8 This patch fixes a problem encountered by the CellSPU backend where variants ... were being pruned in patterns where a variable was used more than once, e.g.: (or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC))) In this example, $rC is used more than once and is actually significant to instruction selection pattern matching when commuted variants are produced. This patch scans the pattern's clauses and collects the variables, creating a set of variables that are used more than once. TreePatternNode::isIsomorphicTo() also understands that multiply-used variables are significant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47950 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-05 17:49:05 +00:00
