-// This file defines arena allocators.

-// Almost all large objects, such as files, sections or symbols, are
-// used for the entire lifetime of the linker once they are created.
-// This usage characteristic makes arena allocator an attractive choice
-// where the entire linker is one arena. With an arena, newly created
-// objects belong to the arena and freed all at once when everything is done.
-// Arena allocators are efficient and easy to understand.
-// Most objects are allocated using the arena allocators defined by this file.
