enumerateComponents()

void SwiftAggLowering::enumerateComponents

Enumerate the expanded components of this type.

The component types will always be legal vector, floating-point, integer, or pointer types.

getCoerceAndExpandTypes()

std::pair< llvm::StructType *, llvm::Type * > SwiftAggLowering::getCoerceAndExpandTypes

(

)

const

Return the types for a coerce-and-expand operation.

The first type matches the memory layout of the data that's been added to this structure, including explicit [N x i8] arrays for any internal padding.

The second type removes any internal padding members and, if only one element remains, is simply that element type.

shouldPassIndirectly()

bool SwiftAggLowering::shouldPassIndirectly

(

bool

asReturnValue

)

const

According to the target Swift ABI, should a value with this lowering be passed indirectly?

Note that this decision is based purely on the data layout of the value and does not consider whether the type is address-only, must be passed indirectly to match a function abstraction pattern, or anything else that is expected to be handled by high-level lowering.

Parameters

asReturnValue

- if true, answer whether it should be passed indirectly as a return value; if false, answer whether it should be passed indirectly as an argument
