Targets can subclass this to parameterize the SelectionDAG lowering and instruction selection process...
StringRef - Represent a constant reference to a string, i.e.
constexpr bool empty() const
empty - Check if the string is empty.
Primary interface to the complete machine description for the target machine.
Triple - Helper class for working with autoconf configuration names.
constexpr char Align[]
Key for Kernel::Arg::Metadata::mAlign.

This is an optimization pass for GlobalISel generic memory operations.
