needs to update it if it's already around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53049 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02Add a new getMergeValues method that does not needDuncan Sands
to be passed the list of value types, and use this where appropriate. Inappropriate places are where the value type list is already known and may be long, in which case the existing method is more efficient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53035 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02Fixed problem in EmitStackConvert where the source and target typeMon P Wang

2008-07-02instead of aborting on shifts of i1, just implicitly fold them.Chris Lattner
The dag combiner can produce a shift of i1 when folding icmp i1's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53030 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-02Let AnalyzeNewNode take care of calling ExpungeNode.Duncan Sands
This makes sure that all new nodes are expunged, not just those the top node of a new subtree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53011 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-01Add a version of AsmPrinter::EOL that takes a const char* so that we don't ↵Owen Anderson
have to do as many implicit std::string constructions. Unfortunately, this doesn't appear to translate to a real speedup in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52981 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52944 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-01Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52930 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30std::ostream and std::string microoptimizations for asm printing.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52929 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Use reserve.Dan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52926 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Rename ISD::LOCATION to ISD::DBG_STOPPOINT to better reflect itsDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52924 91177308-0d34-0410-b5e6-96231b3b80d8

objects. Fixes a couple of tests on Linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52921 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-30Replace some std::vectors that showed up in heap profiling withDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52917 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Correct the allocation size for CCState's UsedRegs member, whichDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52915 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30ExpungeNode is only needed for new nodes! ThisDuncan Sands
fixes CodeGen/PowerPC/2008-06-19-LegalizerCrash.ll when using the new LegalizeTypes infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52903 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Support for VAARG. As noted in a comment, this isDuncan Sands
wrong for types like x86 long double and i1, but no worse than what is done in LegalizeDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52898 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Support for promoting select_cc operands.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52895 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Revert the SelectionDAG optimization that makesDuncan Sands
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52893 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-29Revert (52748 and friends):Anton Korobeynikov
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.
