Andrzej Warzynski [Thu, 29 Dec 2022 10:22:28 +0000 (10:22 +0000)]
[mlir][linalg] Vectorize tensor.extract using contiguous loads

This patch implements vectorization of tensor.extract for n-D tensor (n
>= 2) using contiguous load operations, i.e. `vector.transfer_read`. This
is a follow-up of https://reviews.llvm.org/D137660 in which gather loads
were used, i.e. `vector.gather`.

It is always safe to use gather load operations when the underlying
memory pattern is contiguous, but not vice-verse. At the moment, the
following conditions have to be met for contiguous loads to be
generated:
  1. The _output tensor_ must be a 1-D vector with the trailing dim > 1,
     e.g. `tensor<1x1x4xi32`,
  2. The trailing dim in the _input tensor_ must be > 1, e.g.
     `tensor<1x1x4i32>` would be fine, but not `tensor<1x4x1xi32>`.
If these conditions are not satisfied, gather loads are generated
instead.

Condition 1 guarantees that the iteration space of the corresponding
`linalg.generic` Op is relatively simple. That makes analysing the
indices for `tensor.extract` rather straightforward.

Condition 2 is mostly there to avoid weird vectorisation patterns
resulting in vectors like: `vector<1x1x1xi32>`. In practice, tensors
like `tensor<1x4x1xi32>` should be collapsed to `tensor<1x4xi32>` before
vectorisation, but that's beyond the scope of this patch.

If needed, both conditions can be relaxed. I've not been able to find a
good motivating example for these, hence skipping. For reference,
`tosa.resize` (lowered to Linalg) was the driving example used here.

As a bonus, the test from "vectorization-unsupported.mlir" is moved to
"vectorization.mlir" with proper CHECK lines added.

InstCombine if LowerDbgDeclare makes a change (i.e. it is _sometimes_

InstCombine _always_ call RemoveRedundantDbgInstrs.

Instrumenting the compiler to run RemoveRedundantDbgInstrs after every pass and
dump the numbers and building CTMark/tramp3d-v4 indicates that SROA and
LoopVectorize give us a bigger bang (number removed) for buck (times pass is

This patch achieves this by building an AST and invoking main file
callbacks on each update, in addition to preamble updates.

It means we might have some extra AST builds now (e.g. if an update was
with a stale preamble and there were no reads on it, we would only build
an AST once we had the fresh preamble. Now we'll build 2, once with the
stale preamble and another with the fresh one, but we'll have one more
diagnostics cycle in between.).

This patch preserves forward progress of diagnostics by always using the
latest main file contents when emitting diagnostics after preamble
builds. It also guarantees eventual consistency:
- if an update doesn't invalidate preamble, we'll emit diagnostics with
  fresh preamble already.
- if an update invalidates preamble, we'll first emit diagnostics with
  stale contents, and then once the preamble build finishes it'll emit
  diagnostics (as preamble has changed) with newest version.

This has implications on parsing callbacks, as previously onMainAST
callback was called at most once, now it can be called up to 2 times.
All of the existing clients can already deal with callback firing
multiple times.

Diego Caballero [Wed, 22 Feb 2023 01:20:10 +0000 (01:20 +0000)]
[mlir][Vector] Support masking for more contraction flavors

This patch adds masking support for more contraction flavors including those
with any combiner operation (add, mul, min, max, and, or, etc.) and
regular matmul contractions.

Combiner operations that are performing vertical reductions (and,
therefore, they are not represented with a horizontal reduction
operation) can be executed unmasked. However, the previous value of
the accumulator must be propagated for lanes that shouldn't accumulate.
We achieve this goal by introducing a select operation after the
accumulator to choose between the combined and the previous accumulator
value. This design decision is made to avoid introducing masking support
to all the arithmetic and logical operations in the Arith dialect. VP
intrinsics do not support pass-thru values either so we would have to
generate the same sequence when lowering to LLVM. The op + select
pattern is peepholed by some backend with native masking support for those
operations.

Consequently, this patch removes masking support from the vector.fma
operation to follow the same approach for all the combiner operations.
