The backend can create annonymous local symbols. This can be used for constants that will be passed by reference so it will not have to be lowered to the stack, and then stored into the data section. This also means it's valid to return a pointer to a constant array. Those local symbols that are created, will be managed by the parent decl. Free'ing the parent decl, will also free all of its locals. When a local symbol was created, the index of said symbol will be returned and saved in the `memory` tag of a `WValue` which is then memoized. This means that each 'emit' of this WValue will create a relocation for that constant/symbol and the actual pointer value will be set after relocation phase.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
