2009-10-08Add a form of addPreserved which takes a string argument, to allow passesDan Gohman
to declare that they preserve other passes without needing to pull in additional header file or library dependencies. Convert MachineFunctionPass and CodeGenLICM to make use of this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83555 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-05stop MachineFunctionPass from claiming that it preserves LoopDependence info,Chris Lattner
which causes dependence info to be linked into lli. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83289 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31Reapply r77654 with a fix: MachineFunctionPass's getAnalysisUsageDan Gohman
shouldn't do AU.setPreservesCFG(), because even though CodeGen passes don't modify the LLVM IR CFG, they may modify the MachineFunction CFG, and passes like MachineLoop are registered with isCFGOnly set to true. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77691 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31Revert r77654, it appears to be causing llvm-gcc bootstrap failures, and manyDaniel Dunbar
failures when building assorted projects with clang. --- Reverse-merging r77654 into '.': U include/llvm/CodeGen/Passes.h U include/llvm/CodeGen/MachineFunctionPass.h U include/llvm/CodeGen/MachineFunction.h U include/llvm/CodeGen/LazyLiveness.h U include/llvm/CodeGen/SelectionDAGISel.h D include/llvm/CodeGen/MachineFunctionAnalysis.h U include/llvm/Function.h U lib/Target/CellSPU/SPUISelDAGToDAG.cpp U lib/Target/PowerPC/PPCISelDAGToDAG.cpp U lib/CodeGen/LLVMTargetMachine.cpp U lib/CodeGen/MachineVerifier.cpp U lib/CodeGen/MachineFunction.cpp U lib/CodeGen/PrologEpilogInserter.cpp U lib/CodeGen/MachineLoopInfo.cpp U lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp D lib/CodeGen/MachineFunctionAnalysis.cpp D lib/CodeGen/MachineFunctionPass.cpp U lib/CodeGen/LiveVariables.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77661 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31Manage MachineFunctions with an analysis Pass instead of the AnnotableDan Gohman
mechanism. To support this, make MachineFunctionPass a little more complete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77654 91177308-0d34-0410-b5e6-96231b3b80d8
