      Completely rearchitect the interface between targets and the pass manager. · 12e97307
      Chris Lattner authored
      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.

      1. Use SubtargetFeatures in llc/lli.
      
      2. Propagate feature "string" to all targets.
      
      3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

      Implement Subtarget support · f26625e1

      Implement the X86 Subtarget.
      
      This consolidates the checks for target triple, and setting options based
      on target triple into one place.  This allows us to convert the asm printer
      and isel over from being littered with "forDarwin", "forCygwin", etc. into
      just having the appropriate flags for each subtarget feature controlling
      the code for that feature.
      
      This patch also implements indirect external and weak references in the
      X86 pattern isel, for darwin.  Next up is to convert over the asm printers
      to use this new interface.
