2014-08-20Fix null reference creation in ScheduleDAGInstrs constructor call.Alexey Samsonov1-1/+1
Both MachineLoopInfo and MachineDominatorTree may be null in ScheduleDAGMI constructor call. It is undefined behavior to take references to these values. This bug is reported by UBSan. llvm-svn: 216118

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth1-2/+2
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
2012-06-22Revert r158679 - use case is unclear (and it increases the memory footprint).Hal Finkel1-2/+2
Original commit message: Allow up to 64 functional units per processor itinerary. This patch changes the type used to hold the FU bitset from unsigned to uint64_t. This will be needed for some upcoming PowerPC itineraries. llvm-svn: 159027

llvm-svn: 155364
2012-04-18This reverts a long string of commits to the Hexagon backend. TheseChandler Carruth1-34/+55
commits have had several major issues pointed out in review, and those issues are not being addressed in a timely fashion. Furthermore, this was all committed leading up to the v3.1 branch, and we don't need piles of code with outstanding issues in the branch. It is possible that not all of these commits were necessary to revert to get us back to a green state, but I'm going to let the Hexagon maintainer sort that out. They can recommit, in order, after addressing the feedback. Reverted commits, with some notes: Primary commit r154616: HexagonPacketizer - There are lots of review comments here. This is the primary reason for reverting. In particular, it introduced large amount of warnings due to a bad construct in tablegen. - Follow-up commits that should be folded back into this when reposting: - r154622: CMake fixes - r154660: Fix numerous build warnings in release builds. - Please don't resubmit this until the three commits above are included, and the issues in review addressed. Primary commit r154695: Pass to replace transfer/copy ... - Reverted to minimize merge conflicts. I'm not aware of specific issues with this patch. Primary commit r154703: New Value Jump. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154703: Remove iostream usage - r154758: Fix CMake builds - r154759: Fix build warnings in release builds - Please incorporate these fixes and and review feedback before resubmitting. Primary commit r154829: Hexagon V5 (floating point) support. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154841: Remove unused variable (fixing build warnings) There are also accompanying Clang commits that will be reverted for consistency. llvm-svn: 155047

2012-03-07misched preparation: clarify ScheduleDAG and ScheduleDAGInstrs roles.Andrew Trick1-1/+3
ScheduleDAG is responsible for the DAG: SUnits and SDeps. It provides target hooks for latency computation. ScheduleDAGInstrs extends ScheduleDAG and defines the current scheduling region in terms of MachineInstr iterators. It has access to the target's scheduling itinerary data. ScheduleDAGInstrs provides the logic for building the ScheduleDAG for the sequence of MachineInstrs in the current region. Target's can implement highly custom schedulers by extending this class. ScheduleDAGPostRATDList provides the driver and diagnostics for current postRA scheduling. It maintains a current Sequence of scheduled machine instructions and logic for splicing them into the block. During scheduling, it uses the ScheduleHazardRecognizer provided by the target. Specific changes: - Removed driver code from ScheduleDAG. clearDAG is the only interface needed. - Added enterRegion/exitRegion hooks to ScheduleDAGInstrs to delimit the scope of each scheduling region and associated DAG. They should be used to setup and cleanup any region-specific state in addition to the DAG itself. This is necessary because we reuse the same ScheduleDAG object for the entire function. The target may extend these hooks to do things at regions boundaries, like bundle terminators. The hooks are called even if we decide not to schedule the region. So all instructions in a block are "covered" by these calls. - Added ScheduleDAGInstrs::begin()/end() public API. - Moved Sequence into the driver layer, which is specific to the scheduling algorithm. llvm-svn: 152208

2012-02-15Fix library visibility problems with VLIWPacketizer.Andrew Trick1-6/+19
The existing framework for postra scheduling is library local. We want to keep it that way. Soon we will have a more general MachineScheduler interface. At that time, various bits will be exposed to targets. In the meantime, the VLIWPacketizer wants to use ScheduleDAGInstrs directly, so it needs to wrapped in a PIMPL to avoid exposing it to the target interface. llvm-svn: 150633
