lowerArgument

public · function · Source (opens in a new tab)

ArgLowering sun::codegen::abi::aapcs64::lowerArgument(llvm::Type *type, const llvm::DataLayout &dl, Variant variant=Variant::Elf, bool isSigned=false)

Classify one type as it would be passed as a parameter.

Classifies an LLVM argument using the target C calling convention.

isSigned only matters for the Darwin variant's small-integer extension.
