Name

Description

ArgFlagsTy [constructor]

Construct default argument flags with zero alignments.

getByRefSize

Return the size in bytes of a byref argument.

getByValSize

Return the size in bytes of a byval argument.

getFlags

Return the argument's boolean flags.

getNonZeroByValAlign

Return the byval alignment; requires the byval flag to be set.

getNonZeroMemAlign

Return the memory alignment, or 1 if unset.

getNonZeroOrigAlign

Return the original alignment, or 1 if unset.

getPointerAddrSpace

Return the address space of a pointer argument.

isByRef

Return true if the argument is passed by reference in memory.

isByVal

Return true if the argument is a struct passed by value.

isCFGuardTarget

Return true if the argument is a Control Flow Guard target.

isCopyElisionCandidate

Return true if the argument is a copy‐elision candidate.

isHva

Return true if the argument is an HVA field.

isHvaStart

Return true if the argument starts an HVA structure.

isInAlloca

Return true if the argument is passed with inalloca.

isInConsecutiveRegs

Return true if the argument is passed in consecutive registers.

isInConsecutiveRegsLast

Return true if this is the last of consecutive‐register parts.

isInReg

Return true if the argument is passed in a register.

isNest

Return true if the argument is a nested‐function static chain.

isNoExt

Return true if the argument has no extension.

isPointer

Return true if the argument is a pointer.

isPreallocated

Return true if the argument is preallocated (byval without the copy).

isReturned

Return true if the argument is always returned.

isSExt

Return true if the argument is sign‐extended.

isSRet

Return true if the argument is a hidden struct‐return pointer.

isSecArgPass

Return true if the argument is a second‐argument‐pass value.

isSplit

Return true if the argument is part of a split.

isSplitEnd

Return true if this is the last part of a split argument.

isSwiftAsync

Return true if the argument is a Swift async context parameter.

isSwiftError

Return true if the argument is a Swift error parameter.

isSwiftSelf

Return true if the argument is a Swift self parameter.

isVarArg

Return true if the argument is part of a variable argument list.

isZExt

Return true if the argument is zero‐extended.
