static bool | needsLegalizingToDifferentSize (const LegalizeAction Action) |
static SizeAndActionsVec | unsupportedForDifferentSizes (const SizeAndActionsVec &v) |

static SizeAndActionsVec | widenToLargerTypesAndNarrowToLargest (const SizeAndActionsVec &v) |
A SizeChangeStrategy for the common case where legalization for a particular operation consists of widening the type to a large legal type, unless there is no such type and then instead it should be narrowed to the largest legal type. More... | |
