* Make SDNode constructors take a DebugLoc always.Dale Johannesen2009-02-071-52/+34
| | | | | | | | | | | Adjust derived classes to pass UnknownLoc where a DebugLoc does not make sense. Pick one of DebugLoc and non-DebugLoc variants to survive for all such classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64000 91177308-0d34-0410-b5e6-96231b3b80d8

* Take the next steps in making SDUse more consistent with LLVM Use, anddjg2009-01-261-178/+161
| | | | | | | | | | | | | | | | | | tidy up SDUse and related code. - Replace the operator= member functions with a set method, like LLVM Use has, and variants setInitial and setNode, which take care up updating use lists, like LLVM Use's does. This simplifies code that calls these functions. - getSDValue() is renamed to get(), as in LLVM Use, though most places can either use the implicit conversion to SDValue or the convenience functions instead. - Fix some more node vs. value terminology issues. Also, eliminate the one remaining use of SDOperandPtr, and SDOperandPtr itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62995 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove SDNode's virtual destructor. This makes it impossible forDan Gohman2009-01-191-36/+1
| | | | | | | | | | | | | | | SDNode subclasses to keep state that requires non-trivial destructors, however it was already effectively impossible, since the destructor isn't actually ever called. There currently aren't any SDNode subclasses affected by this, and in general it's desireable to keep SDNode objects light-weight. This eliminates the last virtual member function in the SDNode class, so it eliminates the need for a vtable pointer, making SDNode smaller. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62539 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up the atomic opcodes in SelectionDAG.Dan Gohman2008-12-231-156/+43
| | | | | | | | | | | | | | This removes all the _8, _16, _32, and _64 opcodes and replaces each group with an unsuffixed opcode. The MemoryVT field of the AtomicSDNode is now used to carry the size information. In tablegen, the size-specific opcodes are replaced by size-independent opcodes that utilize the ability to compose them with predicates. This shrinks the per-opcode tables and makes the code that handles atomics much more concise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61389 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | "It simplifies the type legalization part a bit, and produces better code by teaching SelectionDAG about the extra bits in an i8 SADDO/UADDO node. In essence, I spontaneously decided that on x86 this i8 boolean result would be either 0 or 1, and on other platforms 0/1 or 0/-1, depending on whether the platform likes it's boolean zero extended or sign extended." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59864 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | the condition for a BRCOND, according to what is returned by getSetCCResultContents. Since all targets return the same thing (ZeroOrOneSetCCResult), this should be harmless! The point is that all over the place the result of SETCC is fed directly into BRCOND. On machines for which getSetCCResultContents returns ZeroOrNegativeOneSetCCResult, this is a sign-extended boolean. So it seems dangerous to also feed BRCOND zero-extended booleans in some circumstances - for example, when promoting the condition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58861 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach DAGCombine to fold constant offsets into GlobalAddress nodes,Dan Gohman2008-10-181-3/+4
| | | | | | | | | | | | | | | | | | | | | | | and add a TargetLowering hook for it to use to determine when this is legal (i.e. not in PIC mode, etc.) This allows instruction selection to emit folded constant offsets in more cases, such as the included testcase, eliminating the need for explicit arithmetic instructions. This eliminates the need for the C++ code in X86ISelDAGToDAG.cpp that attempted to achieve the same effect, but wasn't as effective. Also, fix handling of offsets in GlobalAddressSDNodes in several places, including changing GlobalAddressSDNode's offset from int to int64_t. The Mips, Alpha, Sparc, and CellSPU targets appear to be unaware of GlobalAddress offsets currently, so set the hook to false on those targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57748 91177308-0d34-0410-b5e6-96231b3b80d8
