Chris Lattner	4fbb612685	Handle cracked instructions in dispatch group formation. llvm-svn: 26721	2006-03-13 05:20:04 +00:00
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
Chris Lattner	543832d39d	Change the interface for getting a target HazardRecognizer to be more clean. llvm-svn: 26608	2006-03-08 04:25:59 +00:00
Chris Lattner	8c73d80b08	add a couple more load/store instrs, add a newline to the end of file. llvm-svn: 26594	2006-03-07 16:19:46 +00:00
Nate Begeman	3e3219cc0a	This kinda sorta implements "things that have to lead a dispatch group". llvm-svn: 26591	2006-03-07 08:30:27 +00:00
Chris Lattner	2cab13573c	Implement a very very simple hazard recognizer for LSU rejects and ctr set/read flushes llvm-svn: 26587	2006-03-07 06:32:48 +00:00
