ZIR instructions updated: atomic_load, atomic_rmw, atomic_store, cmpxchg These no longer construct a pointer type as the result location. This solves a TODO that was preventing the pointer from possibly being volatile, as well as properly handling allowzero and addrspace. It also allows the pointer to be over-aligned, which may be needed depending on the target. As a consequence, the element type needs to be communicated in the ZIR. This is done by strategically making one of the operands be ResultLoc.ty instead of ResultLoc.coerced_ty if possible, or otherwise explicitly adding elem_type into the ZIR encoding, such as in the case of atomic_load. The pointer type of atomic operations is now checked in Sema by coercing it to an expected pointer type, that maybe over-aligned according to target requirements. Together with the previous commit, Zig now has smaller alignment for large integers, depending on the target, and yet still has type safety for atomic operations that specially require higher alignment.

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.
