2009-12-11Address comments on last patch:Bill Wendling
- Loosen the restrictions when checking of it branches to a landing pad. - Make the loop more efficient by checking the '.insert' return value. - Do cheaper checks first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91101 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-11A machine basic block may end in an unconditional branch, however it may haveBill Wendling
more than one successor. Normally, these extra successors are dead. However, some of them may branch to exception handling landing pads. If we remove those successors, then the landing pads could go away if all predecessors to it are removed. Before, it was checking if the direct successor was the landing pad. But it could be the result of jumping through multiple basic blocks to get to it. If we were to only check for the existence of an EH_LABEL in the basic block and not remove successors if it's in there, then it could stop actually dead basic blocks from being removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91092 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-26Split tail duplication into a separate pass. This is needed to avoidBob Wilson
running tail duplication when doing branch folding for if-conversion, and we also want to be able to run tail duplication earlier to fix some reg alloc problems. Move the CanFallThrough function from BranchFolding to MachineBasicBlock so that it can be shared by TailDuplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89904 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18Fix a bug in sdisel switch lowering code. When it updates the phi nodes in ↵Evan Cheng
switch successor blocks, it can introduce multiple phi operands of the same value from different blocks (and may not be on the predecessor list). This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82214 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-25re-committing yesterday's r79938.Gabor Greif
This time there is no additional include of llvm/Config/config.h at all. Instead I use a hard-coded preprecessor symbol: LLVM_COMPACTIFY_SENTINELS (should this work on the self-hosting buildbot, then cleanups come next) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80035 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-24Resubmit an earlier patch of mine:Gabor Greif
reduce the size of relevant "ghostly" sentinels by a pointer. This attempt now makes the compactification dependent on the configure variable LLVM_COMPACT_SENTINELS and should not cause any bootstrap failures for llvm-gcc any more. Please note that this is not yet the final version, and (as settled with Chris) I shall take out the autofoo/cmake portions in the next days. This will also lose the assertability on sentinel dereferencing and operator++, but that seems an acceptable price to pay for the simplified build logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79938 91177308-0d34-0410-b5e6-96231b3b80d8

a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement.
