Detailed Description

TypeBuilder manages the lifecycle of ABI types using bump pointer allocation.

Types created by a TypeBuilder are valid for the lifetime of the allocator.

Example usage:

BumpPtrAllocator Alloc;
TypeBuilder Builder(Alloc);
const auto *IntTy = Builder.getIntegerType(32, Align(4), true);

getScalablePredicateOrCountVectorType()

const VectorType * llvm::abi::TypeBuilder::getScalablePredicateOrCountVectorType ( Align ABIAlign, VectorKind Kind )

inline

Creates a scalable predicate or count vector.

Note: The AArch64 __SVCount_t type is opaque, so it is modeled with the shape of svbool_t: a scalable vector of 16 one-bit elements.

getTupleType()

const TupleType * llvm::abi::TypeBuilder::getTupleType ( const VectorType * Vec, unsigned NumVectors )

inline

Creates a homogeneous tuple of NumVectors copies of Vec.

NumVectors must be 2, 3, or 4.
