Machine Value Type.
Targets can subclass this to parameterize the SelectionDAG lowering and instruction selection process...
StringRef - Represent a constant reference to a string, i.e.

Triple - Helper class for working with autoconf configuration names.
Definition: Triple.h:44
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
This struct is a compact representation of a valid (non-zero power of two) alignment.
