This way the generated code only has to setup the stack size at the beginning of a function and this improves codegen. Fixes #7689 ``` fn foo() void {} export fn hello(z: i8) void { var x: i16 = undefined; foo(); var y: i32 = 1; y += z; } ``` llvm-ir: ``` define void @hello(i8 %0) { Entry: %1 = alloca i8, align 1 %2 = alloca i16, align 2 %3 = alloca i32, align 4 store i8 %0, i8* %1, align 1 %4 = load i8, i8* %1, align 1 store i16 undef, i16* %2, align 2 call void @foo() store i32 1, i32* %3, align 4 %5 = load i32, i32* %3, align 4 %6 = sext i8 %4 to i32 %7 = add nsw i32 %5, %6 store i32 %7, i32* %3, align 4 ret void } ```
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

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.
