The switch_br ZIR instructions are now switch_block instructions. This avoids a pointless block always surrounding a switchbr in emitted ZIR code. Introduce typeof_elem ZIR instruction for getting the type of the element of a pointer value in 1 instruction. Change typeof to be un_node, not un_tok. Introduce switch_capture ZIR instructions for obtaining the capture value of switch prongs. Introduce Sema.resolveBody for when you want to extract a *Inst out of a block and you know that there is only going to be 1 break from it. What's not working yet: AstGen does not correctly elide store instructions when it turns out that the result location does not need to be used as a pointer. Also Sema validation code for duplicate switch items is not yet implemented.
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.
