This replaces TableGen's type inference to operate on parameterized types instead of MVTs, and as a consequence, some interfaces have changed: - Uses of MVTs are replaced by ValueTypeByHwMode. - EEVT::TypeSet is replaced by TypeSetByHwMode. This affects the way that types and type sets are printed, and the tests relying on that have been updated. There are certain users of the inferred types outside of TableGen itself, namely FastISel and GlobalISel. For those users, the way that the types are accessed have changed. For typical scenarios, these replacements can be used: - TreePatternNode::getType(ResNo) -> getSimpleType(ResNo) - TreePatternNode::hasTypeSet(ResNo) -> hasConcreteType(ResNo) - TypeSet::isConcrete -> TypeSetByHwMode::isValueTypeByHwMode(false) For more information, please refer to the review page.
