Tagged union holding either a T or a Error.
LLVM Value Representation.
A range adaptor for a pair of iterators.
This class implements an extremely fast bulk output stream that can only output to a stream.
This provides a very simple, boring adaptor for a begin and end iterator into a range type.
This is an optimization pass for GlobalISel generic memory operations.
