Summary: The attribute grammar includes an optional trailing colon type, so for attributes without a constant buildable type this will generally lead to unexpected and undesired behavior. Given that, it's better to just error out on these cases.

Summary: It is a very common user trap to think that the location printed along with the diagnostic is the same as the current operation that caused the error. This revision changes the behavior to always print the current operation, except for when diagnostics are being verified. This is achieved by moving the command line flags in IR/ to be options on the MLIRContext.

This slightly tweaks the generated code from:
#ifdef GEN_PASS_REGISTRATION
::mlir::registerPass("flag1", ...
::mlir::registerPass("flag2", ...
#endif // GEN_PASS_REGISTRATION
to:
#ifdef GEN_PASS_REGISTRATION
#define GEN_PASS_REGISTRATION_Pass1
#define GEN_PASS_REGISTRATION_Pass2
#endif // GEN_PASS_REGISTRATION
#ifdef GEN_PASS_REGISTRATION_Pass1
::mlir::registerPass("flag1", ...
#endif
#ifdef GEN_PASS_REGISTRATION_Pass1
::mlir::registerPass("flag2", ...
#endif
That way the generated code can be included by defining the
`GEN_PASS_REGISTRATION` macro as currenty and register all the passes,
but one can also define only `GEN_PASS_REGISTRATION_Pass1` to register a
subset of the passes.
Differential Revision: https://reviews.llvm.org/D77322
There is no need to directly depends on this from mlir-opt, some library
may transitively depend on a subset of the targets when enabled (like
NVPTX for Cuda codegen tests) but this is handled by CMake already.
Summary:
This revision adds support for auto-generating pass documentation, replacing the need to manually keep Passes.md up-to-date. This matches the behavior already in place for dialect and interface documentation.
Differential Revision: https://reviews.llvm.org/D76660
This revision adds support for generating utilities for passes such as options/statistics/etc. that can be inferred from the tablegen definition. This removes additional boilerplate from the pass, and also makes it easier to remove the reliance on the pass registry to provide certain things(e.g. the pass argument).
Differential Revision: https://reviews.llvm.org/D76659
This will greatly simplify a number of things related to passes:
* Enables generation of pass registration
* Enables generation of boiler plate pass utilities
* Enables generation of pass documentation
This revision focuses on adding the basic structure and adds support for generating the registration for passes in the Transforms/ directory. Future revisions will add more support and move more passes over.

The Dominance analysis currently misses a utility function to find the nearest common dominator of two given blocks. This is required for a huge variety of different control-flow analyses and transformations. This commit adds this function and moves the getNode function from DominanceInfo to DominanceInfoBase, as it also works for post dominators.

The Vector Dialect [document](https://mlir.llvm.org/docs/Dialects/Vector/) discusses the vector abstractions that MLIR supports and the various tradeoffs involved.
One of the layer that is missing in OSS atm is the Hardware Vector Ops (HWV) level.
This revision proposes an AVX512-specific to add a new Dialect/Targets/AVX512 Dialect that would directly target AVX512-specific intrinsics.
Atm, we rely too much on LLVM’s peephole optimizer to do a good job from small insertelement/extractelement/shufflevector. In the future, when possible, generic abstractions such as VP intrinsics should be preferred.
The revision will allow trading off HW-specific vs generic abstractions in MLIR.

Summary:
This adds support in RewriterGen for calling into the new `PatternRewriter::notifyMatchFailure` hook. This lets derived pattern rewriters display this information to users, an example from DialectConversion is shown below:
```
Legalizing operation : 'std.and'(0x60e0000066a0) {
* Fold {
} -> FAILURE : unable to fold
* Pattern : 'std.and -> (spv.BitwiseAnd)' {
** Failure : operand 0 of op 'std.and' failed to satisfy constraint: '8/16/32/64-bit integer or vector of 8/16/32/64-bit integer values of length 2/3/4'
} -> FAILURE : pattern failed to match
* Pattern : 'std.and -> (spv.LogicalAnd)' {
** Failure : operand 0 of op 'std.and' failed to satisfy constraint: 'bool or vector of bool values of length 2/3/4'
} -> FAILURE : pattern failed to match
} -> FAILURE : no matched legalization pattern
```

Setting MLIR_TABLEGEN_EXE would prevent building the native tool which is used in cross-compiling
Differential Revision: https://reviews.llvm.org/D75299
Previously extensions and capabilities requirements are returned as
SmallVector<SmallVector>. It's an anti-pattern; this commit improves
a bit by returning as SmallVector<ArrayRef>. This is possible because
the internal sequence is always known statically (from the spec)
so that we can use a static constant array for it and get an ArrayRef.

This commits changes the definition of spv.module to use the #spv.vce
attribute for specifying (version, capabilities, extensions) triple
so that we can have better API and custom assembly form. Since now
we have proper modelling of the triple, (de)serialization is wired up
to use them.
With the new UpdateVCEPass, we don't need to manually specify the
required extensions and capabilities anymore when creating a spv.module.
One just need to call UpdateVCEPass before serialization to get the
needed version/extensions/capabilities.

This was a previous experiment that didn't pan out and needs to be
replaced, given no current use or tests, deleting instead and can start
new version fresh.
HasNoSideEffect can now be implemented using the MemoryEffectInterface, removing the need to check multiple things for the same information. This also removes an easy foot-gun for users as 'Operation::hasNoSideEffect' would ignore operations that dynamically, or recursively, have no side effects. This also leads to an immediate improvement in some of the existing users, such as DCE, now that they have access to more information.
Differential Revision: https://reviews.llvm.org/D76036
The current mechanism for identifying is a bit hacky and extremely adhoc, i.e. we explicit check 1-result, 0-operand, no side-effect, and always foldable and then assume that this is a constant. Adding a trait adds structure to this, and makes checking for a constant much more efficient as we can guarantee that all of these things have already been verified.

The three libs where recently added to the `mlir-cpu-runner`'s
`CMakeLists.txt` file. This prevent the runner to compile on other

Summary:
New classes are added to ODS to enable specifying additional information on the arguments and results of an operation. These classes, `Arg` and `Res` allow for adding a description and a set of 'decorators' along with the constraint. This enables specifying the side effects of an operation directly on the arguments and results themselves.
Example:
```
def LoadOp : Std_Op<"load"> {
let arguments = (ins Arg<AnyMemRef, "the MemRef to load from",
[MemRead]>:$memref,
Variadic<Index>:$indices);
}
```
Differential Revision: https://reviews.llvm.org/D74440
This revision introduces the infrastructure for defining side-effects and attaching them to operations. This infrastructure allows for defining different types of side effects, that don't interact with each other, but use the same internal mechanisms. At the base of this is an interface that allows operations to specify the different effect instances that are exhibited by a specific operation instance. An effect instance is comprised of the following:
* Effect: The specific effect being applied.
For memory related effects this may be reading from memory, storing to memory, etc.
* Value: A specific value, either operand/result/region argument, the effect pertains to.
* Resource: This is a global entity that represents the domain within which the effect is being applied.
MLIR serves many different abstractions, which cover many different domains. Simple effects are may have very different context, for example writing to an in-memory buffer vs a database. This revision defines uses this infrastructure to define a set of initial MemoryEffects. The are effects that generally correspond to memory of some kind; Allocate, Free, Read, Write.
This set of memory effects will be used in follow revisions to generalize various parts of the compiler, and make others more powerful(e.g. DCE).
This infrastructure was originally proposed here:

Differential Revision: https://reviews.llvm.org/D74439
Putting this up mainly for discussion on
how this should be done. I am interested in MLIR from
the Julia side and we currently have a strong preference
to dynamically linking against the LLVM shared library,
and would like to have a MLIR shared library.
This patch adds a new cmake function add_mlir_library()
which accumulates a list of targets to be compiled into
libMLIR.so. Note that not all libraries make sense to
be compiled into libMLIR.so. In particular, we want
to avoid libraries which primarily exist to support
certain tools (such as mlir-opt and mlir-cpu-runner).
Note that the resulting libMLIR.so depends on LLVM, but
does not contain any LLVM components. As a result, it
is necessary to link with libLLVM.so to avoid linkage
errors. So, libMLIR.so requires LLVM_BUILD_LLVM_DYLIB=on
FYI, Currently it appears that LLVM_LINK_LLVM_DYLIB is broken
because mlir-tblgen is linked against libLLVM.so and
and independent LLVM components.
Previous version of this patch broke depencies on TableGen
targets. This appears to be because it compiled all
libraries to OBJECT libraries (probably because cmake
is generating different target names). Avoiding object
libraries results in correct dependencies.

add_llvm_library and add_llvm_executable may need to create new targets with
appropriate dependencies. As a result, it is not sufficient in some
configurations (namely LLVM_BUILD_LLVM_DYLIB=on) to only call
add_dependencies(). Instead, the explicit TableGen dependencies must
be passed to add_llvm_library() or add_llvm_executable() using the DEPENDS
keyword.
Differential Revision: https://reviews.llvm.org/D74930
CMake allows calling target_link_libraries() without a keyword,
but this usage is not preferred when also called with a keyword,
and has surprising behavior. This patch explicitly specifies a
keyword when using target_link_libraries().

Summary:
This revision removes all of the functionality related to successor operands on the core Operation class. This greatly simplifies a lot of handling of operands, as well as successors. For example, DialectConversion no longer needs a special "matchAndRewrite" for branching terminator operations.(Note, the existing method was also broken for operations with variadic successors!!)
This also enables terminator operations to define their own relationships with successor arguments, instead of the hardcoded "pass-through" behavior that exists today.
Differential Revision: https://reviews.llvm.org/D75318
This greatly simplifies the requirements for builders using this mechanism for managing variadic operands.
Differential Revision: https://reviews.llvm.org/D75317
This attribute details the segment sizes for operand groups within the operation. This revision add support for automatically populating this attribute in the declarative parser.
Differential Revision: https://reviews.llvm.org/D75315
This interface contains the necessary components to provide the same builtin behavior that terminators have. This will be used in future revisions to remove many of the hardcoded constraints placed on successors and successor operands. The interface initially contains three methods:
```c++
// Return a set of values corresponding to the operands for successor 'index', or None if the operands do not correspond to materialized values.
Optional<OperandRange> getSuccessorOperands(unsigned index);
// Return true if this terminator can have it's successor operands erased.
bool canEraseSuccessorOperand();
// Erase the operand of a successor. This is only valid to call if 'canEraseSuccessorOperand' returns true.
void eraseSuccessorOperand(unsigned succIdx, unsigned opIdx);
```
Differential Revision: https://reviews.llvm.org/D75314
This allows for simplifying OpDefGen, as well providing specializing accessors for the different successor counts. This mirrors the existing traits for operands and results.
