Benjamin Kramer 0ad6107994 Apply clang-tidy's misc-static-assert where it makes sense.
Also fold conditions into assert(0) where it makes sense. No functional
change intended.

Duncan P. N. Exon Smith 0ce039da16 CodeGen: Update DFAPacketizer API to take MachineInstr&, NFC
In all but one case, change the DFAPacketizer API to take MachineInstr&
instead of MachineInstr*.  In DFAPacketizer::endPacket(), take
MachineBasicBlock::iterator.  Besides cleaning up the API, this is in
search of PR26753.

Duncan P. N. Exon Smith 20a62528ef Revert "CodeGen: MachineInstr::getIterator() => getInstrIterator(), NFC"
This reverts commit r261504, since it's not obvious the new name is
better:
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20160222/334298.html

I'll recommit if we get consensus that it's the right direction.

Duncan P. N. Exon Smith 6e5736e1aa CodeGen: MachineInstr::getIterator() => getInstrIterator(), NFC
Delete MachineInstr::getIterator(), since the term "iterator" is
overloaded when talking about MachineInstr.

- Downcast to ilist_node in iplist::getNextNode() and getPrevNode() so
  that ilist_node::getIterator() is still available.
- Add it back as MachineInstr::getInstrIterator().  This matches the
  naming in MachineBasicBlock.
- Add MachineInstr::getBundleIterator().  This is explicitly called
  "bundle" (not matching MachineBasicBlock) to disintinguish it clearly
  from ilist_node::getIterator().
- Update all calls.  Some of these I switched to `auto` to remove
  boiler-plate, since the new name is clear about the type.

There was one call I updated that looked fishy, but it wasn't clear what
the right answer was.  This was in X86FrameLowering::inlineStackProbe(),
added in r252578 in lib/Target/X86/X86FrameLowering.cpp.  I opted to
leave the behaviour unchanged, but I'll reply to the original commit on
the list in a moment.

Krzysztof Parzyszek 8ad916fe91 [Packetizer] Add a check whether an instruction should be packetized now
Add a function VLIWPacketizerList::shouldAddToPacket, which will allow
specific implementations to decide if it is profitable to add given
instruction to the current packet.

remain as it is currently.

Krzysztof Parzyszek bf390b05bc Hexagon V60/HVX DFA scheduler support
Extended DFA tablegen to:
  - added "-debug-only dfa-emitter" support to llvm-tblgen

  - defined CVI_PIPE* resources for the V60 vector coprocessor

  - allow specification of multiple required resources
    - supports ANDs of ORs
    - e.g. [SLOT2, SLOT3], [CVI_MPY0, CVI_MPY1] means:
           (SLOT2 OR SLOT3) AND (CVI_MPY0 OR CVI_MPY1)

  - added support for combo resources
    - allows specifying ORs of ANDs
    - e.g. [CVI_XLSHF, CVI_MPY01] means:
           (CVI_XLANE AND CVI_SHIFT) OR (CVI_MPY0 AND CVI_MPY1)

  - increased DFA input size from 32-bit to 64-bit
    - allows for a maximum of 4 AND'ed terms of 16 resources

  - supported expressions now include:

    expression     => term [AND term] [AND term] [AND term]
    term           => resource [OR resource]*
    resource       => one_resource | combo_resource
    combo_resource => (one_resource [AND one_resource]*)

Matthias Braun e9564b2bbe ScheduleDAGInstrs: Remove IsPostRA flag; NFC
ScheduleDAGInstrs doesn't behave differently before or after register
allocation. It was only used in a method of MachineSchedulerBase which
behaved differently in MachineScheduler/PostMachineScheduler. Change
this to let MachineScheduler/PostMachineScheduler just pass in a
parameter to that function.

The order of the LiveIntervals* and bool RemoveKillFlags paramters have
been switched to make out-of-tree code fail instead of unintentionally
passing a value intended for the IsPostRA flag to the (previously
following and default initialized) RemoveKillFlags.
