Sergei Larin	2db64a7031	DAG post-process for Hexagon MI scheduler ... This patch introduces a possibility for Hexagon MI scheduler to perform some target specific post- processing on the scheduling DAG prior to scheduling. llvm-svn: 163903	2012-09-14 15:07:59 +00:00
Benjamin Kramer	61f6708eee	Remove redundant private field. ... clang warned about this being unused in Release builds. llvm-svn: 163899	2012-09-14 12:19:58 +00:00
Andrew Trick	7a8e10042f	Reorganize MachineScheduler interfaces and publish them in the header. ... The Hexagon target decided to use a lot of functionality from the target-independent scheduler. That's fine, and other targets should be able to do the same. This reorg and API update makes that easy. For the record, ScheduleDAGMI was not meant to be subclassed. Instead, new scheduling algorithms should be able to implement MachineSchedStrategy and be done. But if need be, it's nice to be able to extend ScheduleDAGMI, so I also made that easier. The target scheduler is somewhat more apt to break that way though. llvm-svn: 163580	2012-09-11 00:39:15 +00:00
Sergei Larin	ef4cc11cf9	Add "blocked" heuristic to the Hexagon MI scheduler. ... Improve AQ instruction selection in the Hexagon MI scheduler. llvm-svn: 163523	2012-09-10 17:31:34 +00:00
Sergei Larin	4d8986af12	Porting Hexagon MI Scheduler to the new API. ... Change current Hexagon MI scheduler to use new converging scheduler. Integrates DFA resource model into it. llvm-svn: 163137	2012-09-04 14:49:56 +00:00
