This commit introduces a new AIR instruction `cmp_lt_errors_len`. It's specific to this use case for two reasons: * The total number of errors is not stable during semantic analysis; it can only be reliably checked when flush() is called. So the backend that is lowering the instruction must emit a relocation of some kind and then populate it during flush(). * The fewer AIR instructions in memory, the better for compiler performance, so we squish complex meanings into AIR tags without hesitation. The instruction is implemented only in the LLVM backend so far. It does this by creating a simple function which is gutted and re-populated with each flush(). AstGen now uses ResultLoc.coerced_ty for `@intToError` and Sema does the coercion. |

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.
