static Type* getPromotedType ( Type * Ty )

static

getPromotedType - Return the specified type promoted as it would be to pass though a va_arg area.

static bool isSafeToEliminateVarargsCast	(	const CallSite	CS,
		const CastInst *const	CI,
		const DataLayout *const	TD,
		const int	ix
	)

static

isSafeToEliminateVarargsCast - If this cast does not affect the value passed through the varargs area, we can eliminate the use of the cast.

static Type* reduceToSingleValueType ( Type * T )

static

reduceToSingleValueType - Given an aggregate type which ultimately holds a single scalar element, like {{{type}}} or [1 x type], return type.

Definition at line 39 of file InstCombineCalls.cpp.
