This class deduplicates shared operation verification code by emitting static functions alongside the op definitions.
These methods are local to the definition file, and are invoked within the operation verify methods. An example is shown below:
static LogicalResult localVerify(...)
LogicalResult OpA::verify(...) { if (failed(localVerify(...))) return failure(); ... }
LogicalResult OpB::verify(...) { if (failed(localVerify(...))) return failure(); ... }

| void StaticVerifierFunctionEmitter::emitOpConstraints | ( | ArrayRef< const llvm::Record * > | opDefs | ) |
Collect and unique all compatible type, attribute, successor, and region constraints from the operations in the file and emit them at the top of the generated file.
Constraints that do not meet the restriction that they can only reference $_self and $_op are not uniqued.

Unique all compatible type and attribute constraints from a pattern file and emit them at the top of the generated file.
Constraints that do not meet the restriction that they can only reference $_self, $_op, and $_builder are not uniqued.

| std::optional< StringRef > StaticVerifierFunctionEmitter::getAttrConstraintFn | ( | const Constraint & | constraint | ) | const |
Get the name of the static function used for the given attribute constraint.
These functions are in the form:
LogicalResult(Operation *op, Attribute attr, StringRef attrName);
If a uniqued constraint was not found, this function returns std::nullopt. The uniqued constraints cannot be used in the context of an OpAdaptor.
Pattern constraints have the form:
LogicalResult(PatternRewriter &rewriter, Operation *op, Attribute attr, StringRef failureStr);
Definition at line 79 of file CodeGenHelpers.cpp.
| StringRef StaticVerifierFunctionEmitter::getRegionConstraintFn | ( | const Constraint & | constraint | ) | const |
Get the name of the static function used for the given region constraint.
These functions are in the form:
LogicalResult(Operation *op, Region ®ion, StringRef regionName, unsigned regionIndex);
The region name may be empty.
Definition at line 94 of file CodeGenHelpers.cpp.
| StringRef StaticVerifierFunctionEmitter::getSuccessorConstraintFn | ( | const Constraint & | constraint | ) | const |
Get the name of the static function used for the given successor constraint.
These functions are in the form:
LogicalResult(Operation *op, Block *successor, StringRef successorName, unsigned successorIndex);
Definition at line 86 of file CodeGenHelpers.cpp.
| StringRef StaticVerifierFunctionEmitter::getTypeConstraintFn | ( | const Constraint & | constraint | ) | const |
Get the name of the static function used for the given type constraint.
These functions are used for operand and result constraints and have the form:
LogicalResult(Operation *op, Type type, StringRef valueKind, unsigned valueIndex);
Pattern constraints have the form:
LogicalResult(PatternRewriter &rewriter, Operation *op, Type type, StringRef failureStr);
