2008-07-27Rename SDOperand to SDValue.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54128 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-22Make the GraphRoot edge look like a chain edge, which is more accurate,Dan Gohman
and use the right result number, in the off chance that the graph root has multiple result values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53923 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21Enhance the GraphWriter support for edge destinations, and teach theDan Gohman
SelectionDAG graph writer to make use of them. Now, nodes with multiple values are displayed as such, with incoming edges pointing to the specific value they use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53875 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21Add titles to the various SelectionDAG viewGraph callsDan Gohman
that include useful information like the name of the block being viewed and the current phase of compilation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53872 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-18Eliminate unused variable.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53772 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-17When printing MemOperand nodes, only use print() forDan Gohman
PseudoSourceValue values, which never have names. Use getName() for all other values, because we want to print just a short summary of the value, not the entire instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53738 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-14Improve debug output for MemOperandSDNode. PseudoSourceValue nodesDan Gohman
don't have value names, so use print instead of getName() to get a useful string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53563 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Revert my previous check-in that split up MachineModuleInfo. It turns out toBill Wendling
slow the compiler down at -O0 some 30% or more. Ooops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53120 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
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
2008-06-21Remove ScheduleDAG's SUnitMap altogether. Instead, use SDNode's NodeIdDan Gohman
field, which is otherwise unused after instruction selection, as an index into the SUnit array. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52583 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-21Change ScheduleDAG's SUnitMap from DenseMap<SDNode*, vector<SUnit*> >Dan Gohman
to DenseMap<SDNode*, SUnit*>, and adjust the way cloned SUnit nodes are handled so that only the original node needs to be in the map. This speeds up llc on 447.dealII.llvm.bc by about 2%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52576 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-06Wrap MVT::ValueType in a struct to get type safetyDuncan Sands
and better control the abstraction. Rename the type to MVT. To update out-of-tree patches, the main thing to do is to rename MVT::ValueType to MVT, and rewrite expressions like MVT::getSizeInBits(VT) in the form VT.getSizeInBits(). Use VT.getSimpleVT() to extract a MVT::SimpleValueType for use in switch statements (you will get an assert failure if VT is an extended value type - these shouldn't exist after type legalization). This results in a small speedup of codegen and no new testsuite failures (x86-64 linux). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52044 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-21Fix an out-of-bounds access in -view-sunit-dags in the case of anDan Gohman
empty ScheduleDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50054 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14In -view-sunit-dags, display "special" chain dependencies as cyanDan Gohman
instead of blue to distinguish them from regular dependencies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49696 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Fix -view-sunit-dags to support cross-rc-copy nodes.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48664 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Introduce a new node for holding call argumentDuncan Sands
flags. This is needed by the new legalize types infrastructure which wants to expand the 64 bit constants previously used to hold the flags on 32 bit machines. There are two functional changes: (1) in LowerArguments, if a parameter has the zext attribute set then that is marked in the flags; before it was being ignored; (2) PPC had some bogus code for handling two word arguments when using the ELF 32 ABI, which was hard to convert because of the bogusness. As suggested by the original author (Nicolas Geoffray), I've disabled it for the moment. Tested with "make check" and the Ada ACATS testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48640 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-26Change "Name" to "AsmName" in the target register info. Gee, a refactoring toolBill Wendling
would have been a Godsend here! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47625 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46930 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-06Re-apply the memory operand changes, with a fix for the staticDan Gohman
initializer problem, a minor tweak to the way the DAGISelEmitter finds load/store nodes, and a renaming of the new PseudoSourceValue objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46827 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-31Revert 46556 and 46585. Dan please fix the PseudoSourceValue problem and ↵Evan Cheng
re-commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46623 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-31Create a new class, MemOperand, for describing memory referencesDan Gohman
in the backend. Introduce a new SDNode type, MemOperandSDNode, for holding a MemOperand in the SelectionDAG IR, and add a MemOperand list to MachineInstr, and code to manage them. Remove the offset field from SrcValueSDNode; uses of SrcValueSDNode that were using it are all all using MemOperandSDNode now. Also, begin updating some getLoad and getStore calls to use the PseudoSourceValue objects. Most of this was written by Florian Brander, some reorganization and updating to TOT by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46585 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-30Factor the addressing mode and the load/store VT out of LoadSDNodeDan Gohman
and StoreSDNode into their common base class LSBaseSDNode. Member functions getLoadedVT and getStoredVT are replaced with the common getMemoryVT to simplify code that will handle both loads and stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46538 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-25Added major new capabilities to scheduler (only BURR for now) to support ↵Evan Cheng
physical register dependency. The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42284 91177308-0d34-0410-b5e6-96231b3b80d8
