Tagged union holding either a T or a Error.

Symbol resolution interface.

RelocationEntry - used to represent relocations internally in the dynamic linker.

Interface for looking up the initializer for a variable name, used by Init::resolveReferences.

SectionEntry - represents a section emitted into memory by the dynamic linker.

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.
