Chris Lattner 33c9ddc91d Completely rearchitect the interface between targets and the pass manager. ... 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. llvm-svn: 30081		2006-09-04 04:14:57 +00:00
