* Add some debug routines to SelectionDAG to dump full DAGs.David Greene2010-01-152-1/+44
| | | | | | | | | | | | print/dumpWithDepth allows one to dump a DAG up to N levels deep. dump/printWithFullDepth prints the whole DAG, subject to a depth limit on 100 in the default case (to prevent infinite recursion). Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly what the non-matching DAG looks like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93538 91177308-0d34-0410-b5e6-96231b3b80d8

* Change pre-regalloc tail duplication to only duplicate indirect branch blocks.Bob Wilson2010-01-151-4/+11
| | | | | | | | | | The pre-regalloc pass caused some regressions in both compile time and performance of the generated code, and it did not improve performance, except for indirect branches. I also moved the check for single-block loops to speed up the common case when running the taildup pass before reg allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93505 91177308-0d34-0410-b5e6-96231b3b80d8
