* wasm: Move wasm's codegen to arch/wasm/CodeGen.zig * wasm: Define Wasm's Mir This declares the initial most-used instructions for wasm as well as the data that represents them. TODO: Add binary operand opcodes. By re-using the wasm opcode values, we can emit each opcode very easily by simply using `@enumToInt()`. However, this poses a possible problem: If we use all of wasm's opcodes, it leaves us no room to use synthetic opcodes such as debugging instructions. We could use reserved opcodes, but the wasm spec may use them at some point. TODO: Check if we should perhaps use a 16bit tag where the highest bits are used for synthetic opcodes. * wasm: Define basic Emit structure * wasm: Implement corresponding Emit functions for MIR * wasm: Initial lowering to MIR - This implements lowering to MIR from AIR for storing and loading of locals as well as emitting immediates. - Relocating function indexes has been simplified a lot as well as we no longer need to patch offsets and we write a relocatable value instead. - Locals are now emitted at the beginning of the function section entry meaning all offsets we generate are stable. * wasm: Lower all AIR instructions to MIR * wasm: Implement remaining MIR instructions * wasm: Fix function relocations * wasm: Get all tests working * wasm: Make `Data` 4 bytes instead of 8. - 64bit immediates are now stored in 2 seperate u32's. - 64bit floats are now stored in 2 seperate u32's. - `mem_arg` is now stored as a seperate payload in extra. |

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.
