* `Type.hasCodeGenBits` this function is used to find out if it ever got sent to a linker backend for lowering. In the case that a struct never has its struct fields resolved, this will be false. In such a case, no corresponding `freeDecl` needs to be issued to the linker backend. So instead of asserting the fields of a struct are resolved, this function now returns `false` for this case. * `Module.clearDecl` there was logic that asserted when there is no outdated_decls map, any dependants of a Decl being cleared had to be in the deletion set. However there is a possible scenario where the dependant is not in the deletion set *yet* because there is a Decl which depends on it, about to be deleted. If it were added to an outdated_decls map, it would be subsequently removed from the map when it gets deleted recursively through its dependency being deleted. These issues were uncovered via unrelated changes which are the two commits immediately preceding this one.

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.
