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.
llvm-svn: 262142
Add a function VLIWPacketizerList::shouldAddToPacket, which will allow
specific implementations to decide if it is profitable to add given
instruction to the current packet.
llvm-svn: 255780
This will make the depedence graph more accurate if an alias analysis
is provided. If nullptr is specified in its place, the behavior will
remain as it is currently.
llvm-svn: 255540
This will allow custom handling of packet finalization. The current
definition of endPacket will still perform the default finalization.
llvm-svn: 255537
Duplicate a few common definitions between DFAPacketizer.cpp and
DFAPacketizerEmitter.cpp to avoid including files from CodeGen
in TableGen.

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]*)

kparzysz: Verified AMDGPU codegen to be unchanged on all llc
tests, except those dealing with instruction encodings.
Reapply the previous patch, this time without circular dependencies.

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.

Thanks to Eugene Kosov for the original patch!

AKA: Recompile *ALL* the source code!
This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

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.

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.

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.
