* Adding dllimport, dllexport and external weak linkage types.Anton Korobeynikov2006-09-141-0/+8
| | | | | | | | | DLL* linkages got full (I hope) codegeneration support in C & both x86 assembler backends. External weak linkage added for future use, we don't provide any codegeneration, etc. support for it. llvm-svn: 30374

* Completely rearchitect the interface between targets and the pass manager.Chris Lattner2006-09-042-77/+22
| | | | | | | | | | | | | | | | | | | | | | | | 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
