2008-11-19Fix debug printing of flagged SDNodes in SUnits so that theyDan Gohman
print in the correct order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59567 91177308-0d34-0410-b5e6-96231b3b80d8

consistent with ScheduleNodeTopDown methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59550 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18Remove integer promotion support for FP_EXTENDDuncan Sands
and FP_ROUND. Not sure what these were doing here - probably they were sometimes (wrongly) created with integer operands somewhere that has since been fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59548 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Simplify code using helper routines. There is notDuncan Sands
supposed to be any functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59545 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18LegalizeTypes support for splitting and scalarizingDuncan Sands
SCALAR_TO_VECTOR. I didn't add the testcase, because once llc gets past scalar-to-vector it hits a SPU target lowering bug and explodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59530 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18Avoid using a loop in ReleasePred and ReleaseSucc methods to compute theDan Gohman
new CycleBound value. Instead, just update CycleBound on each call. Also, make ReleasePred and ReleaseSucc methods more consistent accross the various schedulers. This also happens to make ScheduleDAGRRList's CycleBound computation somewhat more interesting, though it still doesn't have any noticeable effect, because no current targets that use the register-pressure reduction scheduler provide pipeline models. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59475 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-16Improved shuffle normalization to avoid using extract/build when weMon P Wang
can extract using different indexes for two vectors. Added a few tests for vector shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59399 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-15When splitting a SHUFFLE_VECTOR, try to have the resultDuncan Sands
use SHUFFLE_VECTOR instead. If not practical, fall back to the old scheme of building the split result by hand using a BUILD_VECTOR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59361 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-15Add missing widen operations, fixed widening for extracting a subvector,Mon P Wang
and when loading/storing a widen vector, make sure that they are loaded and stored in consecutive order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59357 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-15Move ScheduleDAGList's LatencyPriorityQueue class out to a separate file.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59340 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-14Add support for building a ScheduleDAG from MachineInstrs. This is currentlyDan Gohman
fairly conservative; it doesn't do alias-analysis queries and it doesn't attempt to break anti-dependencies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59324 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-14For post-regalloc scheduling, remove the instructions from the blockDan Gohman
before re-inserting them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59281 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-13Change DOTGraphTraits<ScheduleDAG*>::getGraphName how to find the name ofDan Gohman
the current function on its own, rather than relying on the SelectionDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59277 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Remove the FlaggedNodes member from SUnit. Instead of requiring each SUnitDan Gohman
to carry a SmallVector of flagged nodes, just calculate the flagged nodes dynamically when they are needed. The local-liveness change is due to a trivial scheduling change where the scheduler arbitrary decision differently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59273 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Make the Node member of SUnit private, and add accessors.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59264 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Change ScheduleDAG's DAG member from a reference to a pointer, to prepareDan Gohman
for the possibility of scheduling without a SelectionDAG being present. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59263 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Move the code that inserts X87 FP_REG_KILL instructions from aDan Gohman
special-purpose hook to a new pass. Also, add check to see if any x87 virtual registers are used, to avoid doing any work in the common case that no x87 code is needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59190 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Fix unsigned char->ppcf128 conversion.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59150 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Simplify SplitVecRes_EXTRACT_SUBVECTOR. This meansDuncan Sands
that it no longer handles non-power-of-two vectors. However it previously only handled them sometimes, depending on obscure numerical relationships between the index and vector type. For example, for a vector of length 6, it would succeed if and only if the index was an even multiple of 6. I consider this more confusing than useful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59122 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Correct some thinkos in the expansion of ADD/SUBDuncan Sands
when the target does not support ADDC/SUBC. This fixes PR3044. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59120 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Fix the testb optimization so x86 also bootstraps.Dale Johannesen
Reenable test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59101 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11In ScheduleDAGRRList::CopyAndMoveSuccessors, create the SUnit for the loadDan Gohman
before creating the SUnit for the operation that it was unfolded from. This allows each SUnit to have all of its predecessor SUnits available at the time it is created. I don't know yet if this will be absolutely required, but it is a little tidier to do it this way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59083 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11Avoid relying on the SelectionDAG for initializing the MachineFunction andDan Gohman

2008-11-11Change the scheduler accessor methods to accept an explicit TargetMachineDan Gohman
argument instead of taking the SelectionDAG's TargetMachine. This is needed for some upcoming scheduler changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59055 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11Fix for PR3040:Bill Wendling
The CC was changed, but wasn't checked to see if it was legal if the DAG combiner was being run after legalization. Threw in a couple of checks just to make sure that it's okay. As far as the PR is concerned, no back-end target actually exhibited this problem, so there isn't an associated testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59035 91177308-0d34-0410-b5e6-96231b3b80d8
