Detailed Description
Type storage for SPIR-V structure types:
Structures are uniqued using:
- for identified structs:
- a string identifier;
- for literal structs:
- a list of member types;
- a list of member offset info;
- a list of member decoration info;
- a list of struct decoration info.
Identified structures only have a mutable component consisting of:
- a list of member types;
- a list of member offset info;
- a list of member decoration info;
- a list of struct decoration info.

Member Typedef Documentation
◆ KeyTy
| using mlir::spirv::detail::StructTypeStorage::KeyTy = std::tuple<StringRef, ArrayRef<Type>, ArrayRef<StructType::OffsetInfo>, ArrayRef<StructType::MemberDecorationInfo>, ArrayRef<StructType::StructDecorationInfo> > |
A storage key is divided into 2 parts:
- for identified structs:
- a StringRef representing the struct identifier;
- for literal structs:
- an ArrayRef<Type> for member types;
- an ArrayRef<StructType::OffsetInfo> for member offset info;
- an ArrayRef<StructType::MemberDecorationInfo> for member decoration info;
- an ArrayRef<StructType::StructDecorationInfo> for struct decoration info.
An identified struct type is uniqued only by the first part (field 0) of the key.
A literal struct type is uniqued only by the second part (fields 1, 2, 3 and 4) of the key. The identifier field (field 0) must be empty.

Constructor & Destructor Documentation
◆ StructTypeStorage() [1/2]
|
inline |
Construct a storage object for an identified struct type.
A struct type associated with such storage must call StructType::trySetBody(...) later in order to mutate the storage object providing the actual content.
Definition at line 808 of file SPIRVTypes.cpp.
◆ StructTypeStorage() [2/2]
|
inline |
Construct a storage object for a literal struct type.
A struct type associated with such storage is immutable.
Definition at line 816 of file SPIRVTypes.cpp.
Member Function Documentation
◆ construct()
|
inlinestatic |
If the given key contains a non-empty identifier, this method constructs an identified struct and leaves the rest of the struct type data to be set through a later call to StructType::trySetBody(...).
If, on the other hand, the key contains an empty identifier, a literal struct is constructed using the other fields of the key.

◆ mutate()
|
inline |
Sets the struct type content for identified structs.
Calling this method is only valid for identified structs.
Fails under the following conditions:
- If called for a literal struct;
- If called for an identified struct whose body was set before (through a call to this method) but with different contents from the passed arguments.

References mlir::StorageUniquer::StorageAllocator::copyInto().
◆ operator==()
|
inline |
For identified structs, return true if the given key contains the same identifier.
For literal structs, return true if the given key contains a matching list of member types + offset info + decoration info.
