* Properly handle cases where a predecessor of the block being queried on is ↵Owen Anderson2008-07-011-0/+13

* Replace the dynamically computed std::set lookup method for subregisters ↵Owen Anderson2008-07-011-10/+0

* Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman2008-07-0126-71/+119
| | | | | | | | | | | | | | | | the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. llvm-svn: 52943

* Use reserve.Dan Gohman2008-06-301-0/+1
| | | | | | | | | | SelectionDAG::allnodes_size is linear, but that doesn't appear to outweigh the benefit of reducing heap traffic. If it does become a problem, we should teach SelectionDAG to keep a count of how many nodes are live, because there are several other places where that information would be useful as well. llvm-svn: 52926
* Update comments to new-style syntax.Dan Gohman2008-06-301-3/+3
| | | | llvm-svn: 52925
* Rename ISD::LOCATION to ISD::DBG_STOPPOINT to better reflect itsDan Gohman2008-06-3013-55/+58
| | | | | | | | | | | | | | | | | purpose, and give it a custom SDNode subclass so that it doesn't need to have line number, column number, filename string, and directory string, all existing as individual SDNodes to be the operands. This was the only user of ISD::STRING, StringSDNode, etc., so remove those and some associated code. This makes stop-points considerably easier to read in -view-legalize-dags output, and reduces overhead (creating new nodes and copying std::strings into them) on code containing debugging information. llvm-svn: 52924

* Replace some std::vectors that showed up in heap profiling withDan Gohman2008-06-305-24/+18
| | | | | | | | SmallVectors. Change the signature of TargetLowering::LowerArguments to avoid returning a vector by value, and update the two targets which still use this directly, Sparc and IA64, accordingly. llvm-svn: 52917
* Correct the allocation size for CCState's UsedRegs member, whichDan Gohman2008-06-301-1/+1
| | | | | | | | only needs one bit for each register. UsedRegs is a SmallVector sized at 16, so this eliminates a heap allocation/free for every call and return processed by Legalize on most targets. llvm-svn: 52915

* Revert the SelectionDAG optimization that makesDuncan Sands2008-06-3011-136/+84
| | | | | | | | | | | | | | | | | | it impossible to create a MERGE_VALUES node with only one result: sometimes it is useful to be able to create a node with only one result out of one of the results of a node with more than one result, for example because the new node will eventually be used to replace a one-result node using ReplaceAllUsesWith, cf X86TargetLowering::ExpandFP_TO_SINT. On the other hand, most users of MERGE_VALUES don't need this and for them the optimization was valuable. So add a new utility method getMergeValues for creating MERGE_VALUES nodes which by default performs the optimization. Change almost everywhere to use getMergeValues (and tidy some stuff up at the same time). llvm-svn: 52893

| | | | | | | | | | | | Move GetConstantStringInfo to lib/Analysis. Remove string output routine from Constant. Update all callers. Change debug intrinsic api slightly to accomodate move of routine, these now return values instead of strings. This unbreaks llvm-gcc bootstrap. llvm-svn: 52884
