* Fix a couple of bugs that broke the alpha tester buildChris Lattner2006-03-131-2/+2

* Handle cracked instructions in dispatch group formation.Chris Lattner2006-03-131-14/+27

* Several big changes:Chris Lattner2006-03-121-137/+145
| | | | | | | | | | | 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

* This kinda sorta implements "things that have to lead a dispatch group".Nate Begeman2006-03-071-16/+40

* add some new instructions to the classifier. With this, we correctly insertChris Lattner2006-03-071-0/+11
| | | | | | a nop into Freebench/neural, which speeds it up from 136->129s (~5.4%). llvm-svn: 26590
* add some comments that describe what we modelChris Lattner2006-03-071-3/+18

* Implement a very very simple hazard recognizer for LSU rejects and ctr set/readChris Lattner2006-03-071-0/+203
