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);

getSVECountType()

const VectorType * llvm::abi::TypeBuilder::getSVECountType ( Align ABIAlign )

inline

Creates the AArch64 __SVCount_t type.

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

Creates a homogeneous tuple of NumVectors copies of Vec.

NumVectors must be 2, 3, or 4.
