Make TypeTableBuilder inherit from TypeCollection.

A couple of places in LLD were passing references to
TypeTableCollections around, which makes it hard to change the
implementation at runtime.  However, these cases only needed to
iterate over the types in the collection, and TypeCollection
already provides a handy abstract interface for this purpose.

By implementing this interface, we can get rid of the need to
pass TypeTableBuilder references around, which should allow us
to swap the implementation at runtime in subsequent patches.

[globalisel][tablegen] Fix PR35375 by sign-extending the table value to match getConstantVRegVal()

Summary:
From the bug report:
> The problem is that it fails when trying to compare -65536 (or 4294901760) to 0xFFFF,0000. This is because the
> constant in the instruction is sign extended to 64 bits (0xFFFF,FFFF,FFFF,0000) and then compared to the non
> extended 64 bit version expected by TableGen.
>
> In contrast, the DAGISelEmitter generates special code for AND immediates (OPC_CheckAndImm), which does not
> sign extend.

This patch doesn't introduce the special case for AND (and OR) immediates since the majority of it is related to handling known bits that have no effect on the result and GlobalISel doesn't detect known-bits at this time. Instead this patch just ensures that the immediate is extended consistently on both sides of the check.

Thanks to Diana Picus for the detailed bug report.

6 years ago[CodeView] Refactor / Rewrite TypeSerializer and TypeTableBuilder.
Zachary Turner [Tue, 28 Nov 2017 18:33:17 +0000 (18:33 +0000)]
[CodeView] Refactor / Rewrite TypeSerializer and TypeTableBuilder.

The motivation behind this patch is that future directions require us to
be able to compute the hash value of records independently of actually
using them for de-duplication.

The current structure of TypeSerializer / TypeTableBuilder being a
single entry point that takes an unserialized type record, and then
hashes and de-duplicates it is not flexible enough to allow this.

At the same time, the existing TypeSerializer is already extremely
complex for this very reason -- it tries to be too many things. In
addition to serializing, hashing, and de-duplicating, ti also supports
splitting up field list records and adding continuations. All of this
functionality crammed into this one class makes it very complicated to
work with and hard to maintain.

To solve all of these problems, I've re-written everything from scratch
and split the functionality into separate pieces that can easily be
reused. The end result is that one class TypeSerializer is turned into 3
new classes SimpleTypeSerializer, ContinuationRecordBuilder, and
TypeTableBuilder, each of which in isolation is simple and
straightforward.

A quick summary of these new classes and their responsibilities are:

- SimpleTypeSerializer : Turns a non-FieldList leaf type into a series of
  bytes. Does not do any hashing. Every time you call it, it will
  re-serialize and return bytes again. The same instance can be re-used
  over and over to avoid re-allocations, and in exchange for this
  optimization the bytes returned by the serializer only live until the
  caller attempts to serialize a new record.

- ContinuationRecordBuilder : Turns a FieldList-like record into a series
  of fragments. Does not do any hashing. Like SimpleTypeSerializer,
  returns references to privately owned bytes, so the storage is
  invalidated as soon as the caller tries to re-use the instance. Works
  equally well for LF_FIELDLIST as it does for LF_METHODLIST, solving a
  long-standing theoretical limitation of the previous implementation.

- TypeTableBuilder : Accepts sequences of bytes that the user has already
  serialized, and inserts them by de-duplicating with a hash table. For
  the sake of convenience and efficiency, this class internally stores a
  SimpleTypeSerializer so that it can accept unserialized records. The
  same is not true of ContinuationRecordBuilder. The user is required to
  create their own instance of ContinuationRecordBuilder.

6 years agoAdd a new pass to speculate around PHI nodes with constant (integer) operands when...
Chandler Carruth [Tue, 28 Nov 2017 11:32:31 +0000 (11:32 +0000)]
Add a new pass to speculate around PHI nodes with constant (integer) operands when profitable.

The core idea is to (re-)introduce some redundancies where their cost is
hidden by the cost of materializing immediates for constant operands of
PHI nodes. When the cost of the redundancies is covered by this,
avoiding materializing the immediate has numerous benefits:
1) Less register pressure
2) Potential for further folding / combining
3) Potential for more efficient instructions due to immediate operand

As a motivating example, consider the remarkably different cost on x86
of a SHL instruction with an immediate operand versus a register
operand.

This pattern turns up surprisingly frequently, but is somewhat rarely
obvious as a significant performance problem.

The pass is entirely target independent, but it does rely on the target
cost model in TTI to decide when to speculate things around the PHI
node. I've included x86-focused tests, but any target that sets up its
immediate cost model should benefit from this pass.

There is probably more that can be done in this space, but the pass
as-is is enough to get some important performance on our internal
benchmarks, and should be generally performance neutral, but help with
more extensive benchmarking is always welcome.

One awkward part is that this pass has to be scheduled after
*everything* that can eliminate these kinds of redundancies. This
includes SimplifyCFG, GVN, etc. I'm open to suggestions about better
places to put this. We could in theory make it part of the codegen pass
pipeline, but there doesn't really seem to be a good reason for that --
it isn't "lowering" in any sense and only relies on pretty standard cost
model based TTI queries, so it seems to fit well with the "optimization"
pipeline model. Still, further thoughts on the pipeline position are
welcome.

I've also only implemented this in the new pass manager. If folks are
very interested, I can try to add it to the old PM as well, but I didn't
really see much point (my use case is already switched over to the new
PM).

I've tested this pretty heavily without issue. A wide range of
benchmarks internally show no change outside the noise, and I don't see
any significant changes in SPEC either. However, the size class
computation in tcmalloc is substantially improved by this, which turns
into a 2% to 4% win on the hottest path through tcmalloc for us, so
there are definitely important cases where this is going to make
a substantial difference.

6 years agoAMDGPU: Consistently check for immediates in SIInstrInfo::FoldImmediate

AMDGPU: Consistently check for immediates in SIInstrInfo::FoldImmediate

Summary:
The PeepholeOptimizer pass calls this function solely based on checking
DefMI->isMoveImmediate(), which only checks the MoveImm bit of the
instruction description. So it's up to FoldImmediate itself to properly
check that DefMI *actually* moves from an immediate.

I don't have a separate test case for this, but the next patch introduces
a test case which happens to crash without this change.

This error is caught by the assertion in MachineOperand::getImm().
