When we lower the instruction for `@tagName` we generate a new function if it doesn't exist yet for that decl. This function creates an if-else chain to determine which value was provided. Each tag generates a constant that contains its name as the value. For each tag we generate a case where the pointer of the string is stored in the result slice. The length of the tagname is comptime-known, therefore will be stored in the slice directly without having it being part of the tagname symbol. In the future this can use a jump table instead of an if-else chain, similar to the `switch` instruction. |

License
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.
