Tim Shen a6150de447 [MLIR] Remove generated spaces at eof for generate-test-checks.py. 2020-06-16 11:28:36 -07:00
Tim Shen 25b3806788 [MLIR] Rework generate-test-checks.py to attach CHECK lines to the source (test) file.
Summary:
This patch adds --source flag to indicate the source file. Then it tries to find insert
points in the source file and insert corresponding checks at those places.

Example output from Tensorflow XLA:

// -----

// CHECK-LABEL:   func @main.3(
// CHECK-SAME:                 %[[VAL_0:.*]]: memref<2x2xf32> {xla_lhlo.params = 0 : index},
// CHECK-SAME:                 %[[VAL_1:.*]]: memref<16xi8> {xla_lhlo.alloc = 0 : index, xla_lhlo.liveout = true}) {
// CHECK:           %[[VAL_2:.*]] = constant 0 : index
// CHECK:           %[[VAL_3:.*]] = constant 0 : index
// CHECK:           %[[VAL_4:.*]] = std.view %[[VAL_1]]{{\[}}%[[VAL_3]]][] : memref<16xi8> to memref<2x2xf32>
// CHECK:           "xla_lhlo.tanh"(%[[VAL_0]], %[[VAL_4]]) : (memref<2x2xf32>, memref<2x2xf32>) -> ()
// CHECK:           return
// CHECK:         }
func @main(%value0: tensor<2x2xf32>) -> tensor<2x2xf32> {
  %res = "xla_hlo.tanh"(%value0) : (tensor<2x2xf32>) -> tensor<2x2xf32>
  return %res : tensor<2x2xf32>

Nicolas Vasilache eae76faeea [mlir][Linalg] Retire C++ MatmulOp in favor of a linalg-ods-gen'd op.
Summary:
This revision replaces MatmulOp, now that DRR rules have been dropped.
This revision also fixes minor parsing bugs and a plugs a few holes to get e2e paths working (e.g. library call emission).

During the replacement the i32 version had to be dropped because only the EDSC operators +, *, etc support type inference.

Deciding on a type-polymorphic behavior, and implementing it, is left for future work.

Summary:
This CL introduces an integration test directory for MLIR in general, with
vector dialect integration tests in particular as a first working suite. To
run all the integration tests (and currently just the vector suite):

$ cmake --build . --target check-mlir-integration
[0/1] Running the MLIR integration tests
Testing Time: 0.24s
Passed: 22

The general call is to contribute to this integration test directory with more
tests and other suites, running end-to-end examples that may be too heavy for
the regular test directory, but should be tested occasionally to verify the
health of MLIR.

Similarly to `scf::ForOp`, introduce additional `function_ref` arguments to

its construction. Provide compatibility functions for constructing affine loop
nests using `edsc::ScopedContext`.

`edsc::AffineLoopNestBuilder` and reletad functionality is now deprecated and
will be removed soon, users are expected to switch to `affineLoopNestBuilder`
that provides similar functionality with a simpler OpBuilder-based
implementation.

Alex Zinenko 36150c3637 [mlir] Affine symbols: do not expect AffineScope to always exist
In the affine symbol and dimension check, the code currently assumes
`getAffineScope` and its users `isValidDim` and `isValidSymbol` are only called
on values defined in regions that have a parent Op with `AffineScope` trait.
This is not necessarily the case, and these functions may be called on valid IR
that does not satisfy this assumption. Return `nullptr` from `getAffineScope`
if there is no parent op with `AffineScope` trait. Treat this case
conservatively in `isValidSymbol` by only accepting as symbols the values that
are guaranteed to be symbols (constants, and certain operations). No
modifications are necessary to `isValidDim` that delegates most of the work to
`isValidDim`.

Marcel Koester ff4c510337 [mlir] Extended BufferPlacement to support more sophisticated scenarios in which
allocations cannot be moved freely and can remain in divergent control flow.

The current BufferPlacement pass does not support allocation nodes that carry
additional dependencies (like in the case of dynamic shaped types). These
allocations can often not be moved freely and in turn might remain in divergent
control-flow branches. This requires a different strategy with respect to block
arguments and aliases. This CL adds additinal functionality to support
allocation nodes in divergent control flow while avoiding memory leaks.

George Mitenkov cf2b4d5cb6 [MLIR][SPIRVToLLVM] Implemented shift conversion pattern
This patch has shift ops conversion implementation. In SPIR-V dialect,
`Shift` and `Base` may have different bit width. On the contrary,
in LLVM dialect both `Base` and `Shift` have to be of the same bit width.
This leads to the following cases:
- if `Base` has the same bit width as `Shift`, the conversion is
  straightforward.
- if `Base` has a greater bit width than `Shift`, shift is sign/zero
  extended first. Then the extended value is passed to the shift.
- otherwise the conversion is considered to be illegal.

George Mitenkov d93d8fcdec [MLIR][SPIRVToLLVM] Implemented conversion for arithmetic ops and 3 bitwise ops.
Following the previous revision `D81100`, this commit implements a templated class
that would provide conversion patterns for “straightforward” SPIR-V ops into
LLVM dialect. Templating allows to abstract away from concrete implementation
for each specific op. Those are mainly binary operations. Currently supported
and tested ops are:
- Arithmetic ops: `IAdd`, `ISub`, `IMul`, `FAdd`, `FSub`, `FMul`, `FDiv`,  `FNegate`,
  `SDiv`, `SRem` and  `UDiv`
- Bitwise ops: `BitwiseAnd`, `BitwiseOr`, `BitwiseXor`

The implementation relies on `SPIRVToLLVMConversion` class that makes use of
`OpConversionPattern`.

Jacques Pienaar b0921f68e1 [mlir] Add verify method to adaptor
This allows verifying op-indepent attributes (e.g., attributes that do not require the op to have been created) before constructing an operation. These include checking whether required attributes are defined or constraints on attributes (such as I32 attribute). This is not perfect (e.g., if one had a disjunctive constraint where one part relied on the op and the other doesn't, then this would not try and extract the op independent from the op dependent).

The next step is to move these out to a trait that could be verified earlier than in the generated method. The first use case is for inferring the return type while constructing the op. At that point you don't have an Operation yet and that ends up in one having to duplicate the same checks, e.g., verify that attribute A is defined before querying A in shape function which requires that duplication. Instead this allows one to invoke a method to verify all the traits and, if this is checked first during verification, then all other traits could use attributes knowing they have been verified.

It is a little bit funny to have these on the adaptor, but I see the adaptor as a place to collect information about the op before the op is constructed (e.g., avoiding stringly typed accessors, verifying what is possible to verify before the op is constructed) while being cheap to use even with constructed op (so layer of indirection between the op constructed/being constructed). And from that point of view it made sense to me.

Summary:
`mlir-rocm-runner` is introduced in this commit to execute GPU modules on ROCm
platform. A small wrapper to encapsulate ROCm's HIP runtime API is also inside
the commit.

Due to behavior of ROCm, raw pointers inside memrefs passed to `gpu.launch`
must be modified on the host side to properly capture the pointer values
addressable on the GPU.

LLVM MC is used to assemble AMD GCN ISA coming out from
`ConvertGPUKernelToBlobPass` to binary form, and LLD is used to produce a shared
ELF object which could be loaded by ROCm HIP runtime.

gfx900 is the default target be used right now, although it could be altered via
an option in `mlir-rocm-runner`. Future revisions may consider using ROCm Agent
Enumerator to detect the right target on the system.

Notice AMDGPU Code Object V2 is used in this revision. Future enhancements may
upgrade to AMDGPU Code Object V3.

Bitcode libraries in ROCm-Device-Libs, which implements math routines exposed in
`rocdl` dialect are not yet linked, and is left as a TODO in the logic.

Nicolas Vasilache 6953cf6502 [mlir][Linalg] Add a hoistRedundantVectorTransfers helper function
This revision adds a helper function to hoist vector.transfer_read /
vector.transfer_write pairs out of immediately enclosing scf::ForOp
iteratively, if the following conditions are true:
   1. The 2 ops access the same memref with the same indices.
   2. All operands are invariant under the enclosing scf::ForOp.
   3. No uses of the memref either dominate the transfer_read or are
   dominated by the transfer_write (i.e. no aliasing between the write and
   the read across the loop)

To improve hoisting opportunities, call the `moveLoopInvariantCode` helper
function on the candidate loop above which to hoist. Hoisting the transfers
results in scf::ForOp yielding the value that originally transited through
memory.

This revision additionally exposes `moveLoopInvariantCode` as a helper in
LoopUtils.h and updates SliceAnalysis to support return scf::For values and
allow hoisting across multiple scf::ForOps.

Uday Bondhugula 0f6999af88 [MLIR] Update linalg.conv lowering to use affine load in the absence of padding
Update linalg to affine lowering for convop to use affine load for input
whenever there is no padding. It had always been using std.loads because
max in index functions (needed for non-zero padding if not materializing
zeros) couldn't be represented in the non-zero padding cases.

In the future, the non-zero padding case could also be made to use
affine - either by materializing or using affine.execute_region. The
latter approach will not impact the scf/std output obtained after
lowering out affine.

River Riddle c0cd1f1c5c [mlir] Refactor BoolAttr to be a special case of IntegerAttr
This simplifies a lot of handling of BoolAttr/IntegerAttr. For example, a lot of places currently have to handle both IntegerAttr and BoolAttr. In other places, a decision is made to pick one which can lead to surprising results for users. For example, DenseElementsAttr currently uses BoolAttr for i1 even if the user initialized it with an Array of i1 IntegerAttrs.

Nicolas Vasilache 3463d9835b [mlir][Linalg] Add a hoistViewAllocOps helper function
This revision adds a helper function to hoist alloc/dealloc pairs and
alloca op out of immediately enclosing scf::ForOp if both conditions are true:
   1. all operands are defined outside the loop.
   2. all uses are ViewLikeOp or DeallocOp.

This is now considered Linalg-specific and will be generalized on a per-need basis.

Pavel Labath 48cd9d9dd8 [Support] Use outs() in ToolOutputFile
Summary:
If the output filename was specified as "-", the ToolOutputFile class
would create a brand new raw_ostream object referring to the stdout.
This patch changes it to reuse the llvm::outs() singleton.

At the moment, this change should be "NFC", but it does enable other
enhancements, like the automatic stdout/stderr synchronization as
discussed on D80803.

I've checked the history, and I did not find any indication that this
class *has* to use a brand new stream object instead of outs() --
indeed, it is special-casing "-" in a number of places already, so this
change fits the pattern pretty well. I suspect the main reason for the
current state of affairs is that the class was originally introduced
(r111595, in 2010) as a raw_fd_ostream subclass, which made any other
solution impossible.

Another potential benefit of this patch is that it makes it possible to
move the raw_ostream class out of the business of special-casing "-" for
stdout handling. That state of affairs does not seem appropriate because
"-" is a valid filename (albeit hard to access with a lot of command
line tools) on most systems. Handling "-" in ToolOutputFile seems more
appropriate.

To make this possible, this patch changes the return type of
llvm::outs() and errs() to raw_fd_ostream&. Previously the functions
were constructing objects of that type, but returning a generic
raw_ostream reference. This makes it possible for new ToolOutputFile and
other code to use raw_fd_ostream methods like error() on the outs()
object. This does not seem like a bad thing (since stdout is a file
descriptor which can be redirected to anywhere, it makes sense to ask it
whether the writing was successful or if it supports seeking), and
indeed a lot of code was already depending on this fact via the
ToolOutputFile "back door".

Summary:
Different from the fusion between generic ops, indices are involved. In this
context, we need to re-map the indices for producer since the fused op is built
on consumer's perspective. This patch supports all combination of the fusion
between indexed_generic ops and generic ops, which includes tests case:
  1) generic op as producer and indexed_generic op as consumer.
  2) indexed_generic op as producer and generic op as consumer.
  3) indexed_generic op as producer and indexed_generic op as consumer.

Alex Zinenko 6163fa7926 [mlir] DialectConversion: remove vtable from TypeConverter
The original design of TypeConverter expected specific converters to derive the
class and override virtual functions for conversions and materializations. This
did not scale well to multi-dialect conversions, so the design was changed to
register a list of converter and materializer functions, removing the need for
virtual functions. The only remaining virtual function, `convertSignatureArg`
is never overridden in-tree. Make it non-virtual, drop the virtual destructor
and thus remove vtable from TypeConverter.

If there exist TypeConverter users that need custom `convertSignatureArg`
behavior, it should be implemented using the callback registration mechanism
similar to that of conversions and materializations.

Alex Zinenko 5c5dafc534 [mlir] support materialization for 1-1 type conversions
Dialect conversion infrastructure supports 1->N type conversions by requiring
individual conversions to provide facilities to generate operations
retrofitting N values into 1 of the original type when N > 1. This
functionality can also be used to materialize explicit "cast"-like operations,
but it did not support 1->1 type conversions until now. Modify TypeConverter to
support materialization of cast operations for 1-1 conversions.

This also makes materialization specification more extensible following the
same pattern as type conversions. Instead of overloading a virtual function,
users or subclasses of TypeConversion can now register type-specific
materialization callbacks that will be called in order for the given type.
