Similar to function locals, taking the address of a global that does not have an explicit address space assigned to it should result in a generic pointer, not a global pointer. Also similar to function locals, they cannot be generated into the generic storage class, and so are generated into the global storage class and then cast to a generic pointer, using OpSpecConstantOp. Note that using OpSpecConstantOp results is only allowed by a hand full of other OpSpecConstant instructions - which is why we generate constant structs using OpSpecConstantComposite: These may use OpVariable and OpSpecConstantOp results, while OpConstantComposite may not.
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.
