* Change how FP immediates are handled. Nate Begeman2008-02-141-0/+13
| | | | | | | | | | | | | | | 1) ConstantFP is now expand by default 2) ConstantFP is not turned into TargetConstantFP during Legalize if it is legal. This allows ConstantFP to be handled like Constant, allowing for targets that can encode FP immediates as MachineOperands. As a bonus, fix up Itanium FP constants, which now correctly match, and match more constants! Hooray. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47121 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | we are recording variable information at isel time this means parameters would appear in the reverse order. The short term fix is to issue recordVariable() at asm printing time instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46724 91177308-0d34-0410-b5e6-96231b3b80d8
* Change the 'global modification' APIs in SelectionDAG to take a newChris Lattner2008-02-031-22/+35
| | | | | | | | | | | DAGUpdateListener object pointer instead of just returning a vector of deleted nodes. This makes the interfaces more efficient (no more allocating a vector [at least a malloc], filling it in, then walking it) and more clean. This also allows the client to be notified of nodes that are *changed* but not deleted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46677 91177308-0d34-0410-b5e6-96231b3b80d8

* SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng2008-02-025-0/+38
| | | | | | | | | | information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc. Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes. For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46659 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow ComplexExpressions in InstrInfo.td files to be slightly more... ↵Christopher Lamb2008-01-313-6/+28
| | | | | | | | | | | complex! ComplexExpressions can now have attributes which affect how TableGen interprets the pattern when generating matchin code. The first (and currently, only) attribute causes the immediate parent node of the ComplexPattern operand to be passed into the matching code rather than the node at the root of the entire DAG containing the pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46606 91177308-0d34-0410-b5e6-96231b3b80d8
* Create a new class, MemOperand, for describing memory referencesDan Gohman2008-01-311-0/+27
| | | | | | | | | | | | | | | | | 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

* Simplify the side effect stuff a bit more and make licm/sinkingChris Lattner2008-01-101-2/+1
| | | | | | | | | | | | | | | | | both work right according to the new flags. This removes the TII::isReallySideEffectFree predicate, and adds TII::isInvariantLoad. It removes NeverHasSideEffects+MayHaveSideEffects and adds UnmodeledSideEffects as machine instr flags. Now the clients can decide everything they need.

It would be really nice if we could write patterns for copy instructions. I have audited all the x86 instructions down to MOVDQAmr.
