LexicalScope - This class is used to track scope information.
Instances of this class represent a uniqued identifier for a section in the current translation unit.
MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...
This class consists of common code factored out of the SmallVector class to reduce code duplication b...
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.
StringRef - Represent a constant reference to a string, i.e.
This is an optimization pass for GlobalISel generic memory operations.
