Detailed Description

SPIR-V struct type.

Two kinds of struct types are supported:

Literal: a literal struct type is uniqued by its fields (types + offset info + decoration info).
Identified: an indentified struct type is uniqued by its string identifier (name). This is useful in representing recursive structs. For example, the following C struct:

struct A { A* next; };

would be represented in MLIR as:

!spirv.struct<A, (!spirv.ptr<!spirv.struct, Generic>)>

In the above, expressing recursive struct types is accomplished by giving a recursive struct a unique identified and using that identifier in the struct definition for recursive references.

Construct a literal StructType with at least one member.

◆ getEmpty()

StructType StructType::getEmpty	(	MLIRContext *	context,
		StringRef	identifier = `""`
	)

static

Construct a (possibly identified) StructType with no members.

Note: this method might fail in a multi-threaded setup if another thread created an identified struct with the same identifier but with different contents before returning. In which case, an empty (default-constructed) StructType is returned.

◆ getExtensions()

void StructType::getExtensions	(	SPIRVType::ExtensionArrayRefVector &	extensions,
		std::optional< StorageClass >	storage = `std::nullopt`
	)

Definition at line 1117 of file SPIRVTypes.cpp.

References getElementTypes().

◆ getIdentified()

StructType StructType::getIdentified	(	MLIRContext *	context,
		StringRef	identifier
	)

static

Construct an identified StructType.

This creates a StructType whose body (member types, offset info, and decorations) is not set yet. A call to StructType::trySetBody(...) must follow when the StructType contents are available (e.g. parsed or deserialized).

Note: If another thread creates (or had already created) a struct with the same identifier, that struct will be returned as a result.

◆ getIdentifier()

StringRef StructType::getIdentifier ( ) const

For literal structs, return an empty string.

For identified structs, return the struct's identifier.

LogicalResult StructType::trySetBody	(	ArrayRef< Type >	memberTypes,
		ArrayRef< OffsetInfo >	offsetInfo = `{}`,

Sets the contents of an incomplete identified StructType.

This method must be called only for identified StructTypes and it must be called only once per instance. Otherwise, failure() is returned.
