This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

TargetSubtargetInfo - Generic base class for all target subtargets.

The instances of the Type class are immutable: once they are created, they are never changed.

This is an optimization pass for GlobalISel generic memory operations.

auto size(R &&Range, std::enable_if_t< std::is_base_of< std::random_access_iterator_tag, typename std::iterator_traits< decltype(Range.begin())>::iterator_category >::value, void > *=nullptr)

Get the size of a range.
