Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.
namespace	llvm::detail
	These are wrappers over isa* function that allow them to be used in generic algorithms such as llvm:all_of, llvm::none_of, etc.

Detailed Description

This file provides a collection of visitors which walk the (instruction) uses of a pointer.

These visitors all provide the same essential behavior as an InstVisitor with similar template-based flexibility and implementation strategies.

These can be used, for example, to quickly analyze the uses of an alloca, global variable, or function argument.

FIXME: Provide a variant which doesn't track offsets and is cheaper.
