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

2008-03-21Fix -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

2008-02-06Re-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

2008-01-31Create 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.

2005-08-16Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef)Chris Lattner
used to tack a register number onto the node. Instead of doing this, make a new node, RegisterSDNode, which is a leaf containing a register number. These three operations just become normal DAG nodes now, instead of requiring special handling. Note that with this change, it is no longer correct to make illegal CopyFromReg/CopyToReg nodes. The legalizer will not touch them, and this is bad, so don't do it. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22806 91177308-0d34-0410-b5e6-96231b3b80d8
