Include the generated interface declarations.
static constexpr const bool value
This class defines the main interface for locations in MLIR and acts as a non-nullable wrapper around...
Definition: Location.h:48
Operation * create(const OperationState &state)
Creates an operation given the fields represented as an OperationState.
Definition: Builders.cpp:404
bool isCompatibleType(Type type)
Returns true if the given type is compatible with the LLVM dialect.
Definition: LLVMTypes.cpp:854
This class represents an instance of an SSA value in the MLIR system, representing a computable value...
Definition: Value.h:85
StructBuilder(Value v)
Construct a helper for the given value.
Value extractPtr(OpBuilder &builder, Location loc, unsigned pos)
Builds IR to extract a value from the struct at position pos.
void setPtr(OpBuilder &builder, Location loc, unsigned pos, Value ptr)
Builds IR to set a value in the struct at position pos.
This class helps build Operations.
