* Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes.Evan Cheng2006-10-091-7/+5
| | | | | | | | | | | | | | | Chain and address ptr remains as operands. SrcValue, extending mode, extending VT (or rather loaded VT before extension) are now instance variables of LoadSDNode. Introduce load / store addressing modes to represent pre- and post-indexed load and store. Also added an additional operand offset that is only used in post-indexed mode (i.e. base ptr += offset after load/store). Added alignment info (not yet used) and isVolatile fields. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30843 91177308-0d34-0410-b5e6-96231b3b80d8

* Completely rearchitect the interface between targets and the pass manager.Chris Lattner2006-09-042-11/+96
| | | | | | | | | | | | | | | | | | | | | | | | | This pass: 1. Splits TargetMachine into TargetMachine (generic targets, can be implemented any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by things using libcodegen and other support). 2. Instead of having each target fully populate the passmgr for file or JIT output, move all this to common code, and give targets hooks they can implement. 3. Commonalize the target population stuff between file emission and JIT emission. 4. All (native code) codegen stuff now happens in a FunctionPassManager, which paves the way for "fast -O0" stuff in the CFE later, and now LLC could lazily stream .bc files from disk to use less memory. 5. There are now many fewer #includes and the targets don't depend on the scalar xforms or libanalysis anymore (but codegen does). 6. Changing common code generator pass ordering stuff no longer requires touching all targets. 7. The JIT now has the option of "-fast" codegen or normal optimized codegen, which is now orthogonal to the fact that JIT'ing is being done. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30081 91177308-0d34-0410-b5e6-96231b3b80d8
