2008-12-04Use register names instead of numbers in debug output.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60525 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Rewrite the liveness bookkeeping code to fix a bunch ofDan Gohman
issues with subreg operands and tied operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60510 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Fix an inconsistency in a comment.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60500 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Don't charge the full latency for anti and output dependencies. This isDan Gohman
an area where eventually it would be good to use target-dependent information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60498 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03When looking for anti-dependences on the critical path, don't botherDan Gohman
examining non-anti-dependence edges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60496 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Add a comment about callee-saved registers.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60495 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-27Silence a warning.Nick Lewycky
Despite changing the order of evaluation, this doesn't actually change the meaning of the statement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60177 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-25Suppress warnings.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60041 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-25Initial support for anti-dependence breaking. Currently this code does notDan Gohman
introduce any new spilling; it just uses unused registers. Refactor the SUnit topological sort code out of the RRList scheduler and make use of it to help with the post-pass scheduler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59999 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Factor out the code for verifying the work of the scheduler,Dan Gohman
extend it a bit, and make use of it in all schedulers, to ensure consistent checking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59689 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Experimental post-pass scheduling support. Post-pass schedulingDan Gohman
is currently off by default, and can be enabled with -disable-post-RA-scheduler=false. This doesn't have a significant impact on most code yet because it doesn't yet do anything to address anti-dependencies and it doesn't attempt to disambiguate memory references. Also, several popular targets don't have pipeline descriptions yet. The majority of the changes here are splitting the SelectionDAG-specific code out of ScheduleDAG, so that ScheduleDAG can be moved to libLLVMCodeGen.a. The interface between ScheduleDAG-using code and the rest of the scheduling code is somewhat rough and will evolve. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59676 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-04Tidy up several unbeseeming casts from pointer to intptr_t.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55779 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14don't create the post-ra scheduler unless it is enabled.Chris Lattner

2007-07-13Skeleton of post-RA scheduler; doesn't do anything yet.Dale Johannesen
Change name of -sched option and DEBUG_TYPE to pre-RA-sched; adjust testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39816 91177308-0d34-0410-b5e6-96231b3b80d8
