Detailed Description

Attribute collections provide a dictionary-like interface.

Define common lookup functions.

Function Documentation

ensureRegionTerminator() [1/2]

void mlir::impl::ensureRegionTerminator	(	Region &	region,
		Builder &	builder,
		Location	loc,
		function_ref< Operation *(OpBuilder &, Location)>	buildTerminatorOp
	)

Create a simple OpBuilder and forward to the OpBuilder version of this function.

Definition at line 1421 of file Operation.cpp.

ensureRegionTerminator() [2/2]

void mlir::impl::ensureRegionTerminator	(	Region &	region,
		OpBuilder &	builder,
		Location	loc,
		function_ref< Operation *(OpBuilder &, Location)>	buildTerminatorOp
	)

Insert an operation, generated by buildTerminatorOp, at the end of the region's only block if it does not have a terminator already.

If the region is empty, insert a new block first. buildTerminatorOp should return the terminator operation to insert.

findAttrSorted() [1/2]

template<typename IteratorT >

std::pair<IteratorT, bool> mlir::impl::findAttrSorted	(	IteratorT	first,
		IteratorT	last,
		StringAttr	name
	)

StringAttr lookups on large attribute lists will switch to string binary search.

String binary searches become significantly faster than linear scans with the identifier when the attribute list becomes very large.

Definition at line 769 of file OperationSupport.h.

References findAttrSorted(), and findAttrUnsorted().

findAttrSorted() [2/2]

template<typename IteratorT >

std::pair<IteratorT, bool> mlir::impl::findAttrSorted	(	IteratorT	first,
		IteratorT	last,
		StringRef	name
	)

Using llvm::lower_bound requires an extra string comparison to check whether the returned iterator points to the found element or whether it indicates the lower bound.

Skip this redundant comparison by checking if compare == 0 during the binary search.

Definition at line 745 of file OperationSupport.h.

findAttrUnsorted()

template<typename IteratorT , typename NameT >

std::pair<IteratorT, bool> mlir::impl::findAttrUnsorted	(	IteratorT	first,
		IteratorT	last,
		NameT	name
	)

Unsorted string search or identifier lookups are linear scans.

foldCastInterfaceOp()

LogicalResult mlir::impl::foldCastInterfaceOp	(	Operation *	op,
		ArrayRef< Attribute >	attrOperands,
		SmallVectorImpl< OpFoldResult > &	foldResults

getAttrFromSortedRange()

template<typename IteratorT , typename NameT >

Attribute mlir::impl::getAttrFromSortedRange	(	IteratorT	first,
		IteratorT	last,
		NameT	name
	)

Get an attribute from a sorted range of named attributes.

Returns null if the attribute was not found.

template<typename IteratorT , typename NameT >

std::optional<NamedAttribute> mlir::impl::getNamedAttrFromSortedRange	(	IteratorT	first,
		IteratorT	last,
		NameT	name

Get an attribute from a sorted range of named attributes.

Returns std::nullopt if the attribute was not found.

parseOptionalVisibilityKeyword()

ParseResult mlir::impl::parseOptionalVisibilityKeyword	(	OpAsmParser &	parser,
		NamedAttrList &	attrs
	)
