static Type* getPromotedType ( Type Ty) [static]

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

Definition at line 32 of file InstCombineCalls.cpp.

References llvm::Type::getContext(), and llvm::Type::getInt32Ty().

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

Definition at line 1127 of file InstCombineCalls.cpp.

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 42 of file InstCombineCalls.cpp.

References llvm::Type::isSingleValueType(), and T.
