This checkin represents some cleanup of the backend, implementing the following things: 1. The TargetMachine structure is free to decide the process a particular target uses to generate code. 2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory. The Sparc.h file that is globally visible is just a stub. 3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort. llvm-svn: 559 2001-09-14 05:37:52 +02:00			`//===-- llvm/CodeGen/Sparc.h - Sparc Target Description ----------- C++ ---=//`

Header files for the target architecture description and for instruction selection, and instances of these for the SPARC. llvm-svn: 226 2001-07-21 14:39:03 +02:00

Checkin changes to: 1. Clean up the TargetMachine structure. No more wierd pointers that have to be cast around and taken care of by the target. 2. Instruction Scheduling now takes the schedinfo as an argument. The same should be done with the instinfo, it just isn't now. 3. Sparc.h is now just a factory method. Eventually this file will dissapear, but probably not until we have more than one backend. :) llvm-svn: 564 2001-09-14 06:32:38 +02:00			`class TargetMachine;`
Added several SPARC instructions including conditional move and SETHI. Added MachineInstrInfo class and subclass UltraSparcInstrInfo. Added several fields to MachineInstrDescriptor (and renamed it from MachineInstrInfo). Latency fields are to support scheduling. llvm-svn: 313 2001-07-28 06:26:42 +02:00
