◆ AArch64ABIKind

enum class llvm::abi::AArch64ABIKind

strong

Enumerator
AAPCS
DarwinPCS
Win64
AAPCSSoft

Definition at line 109 of file TargetInfo.h.

◆ RecordArgABI

enum llvm::abi::RecordArgABI

Enumerator

RAA_Default

Pass it using the normal C aggregate rules for the ABI, potentially introducing extra copies and passing some or all of it in registers.

RAA_DirectInMemory

Pass it on the stack using its defined layout.

The argument must be evaluated directly into the correct stack position in the arguments area, and the call machinery must not move it or introduce extra copies.

RAA_Indirect

Pass it as a pointer to temporary memory.

◆ VectorKind

enum class llvm::abi::VectorKind

strong

Distinguishes the vector flavors that ABIs have to treat differently.

Scalability is not part of the kind. It is tracked by the vector's ElementCount, because some flavors have both a scalable and a fixed-length spelling.

Enumerator
Generic	A plain vector, such as a Neon vector or a GCC vector_size vector.
SVEData	An AArch64 SVE data vector, such as svint32_t. Data vectors are passed in Z registers. Tuples of these vectors use TupleType.
SVEPredicate	An AArch64 SVE predicate vector, such as svbool_t. These are passed in P registers. Sizeless predicates have one-bit elements; the fixed-length arm_sve_vector_bits form keeps unsigned char (i8) elements, matching the Clang AST. Both use this kind. Tuples of these vectors use TupleType.
SVECount	The AArch64 __SVCount_t type. It is opaque rather than a real vector, but it occupies a predicate register, so it is given the same shape as svbool_t.

Definition at line 236 of file Types.h.

◆ X86AVXABILevel

enum class llvm::abi::X86AVXABILevel

strong

The AVX ABI level for X86 targets.

Enumerator
