Chris Lattner 51348c5f27 Several big changes: ... 1. Use flags on the instructions in the .td file to indicate the PPC970 unit type instead of a table in the .cpp file. Much cleaner. 2. Change the hazard recognizer to build d-groups according to the actual algorithm used, not my flawed understanding of it. 3. Model "must be in the first slot" and "must be the only instr in a group" accurately. llvm-svn: 26719		2006-03-12 09:13:49 +00:00
