The previous commit caused LLVM module verification failure because we attemped to bitcast LLVM pointers to i64 parameters. This is exactly what we want, however it's technically not allowed according to LLVM's type system. It could have been fixed trivially by using ptrtoint instead of bitcast in the case of pointers, however, out of concern for inttoptr being problematic for the optimizer, I put in special code to detect when a given parameter can be treated as its actual type rather than an integer type. This makes Zig's output LLVM IR closer to what Clang outputs.

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.
