В связи с текущими обстоятельствами GSoC 2025 не принимает участников (соавторов, наставников или администраторов организаций) из России, Беларуси или так называемых Донецкой Народной Республики («ДНР») и Луганской Народной Республики («ЛНР»). Никаких ограничений для участников, находящихся на территории Украины, но за пределами ДНР и ЛНР, нет.

Analyzing AIR turned out to be a good decision, and from this project I conclude that Zig AIR is a very good target for many classes of static analysis on Zig code.

This CLR analyzer has been instrumented with four different types of tests:
* Undefined use
* Stack Pointer escape
* Allocation Mistakes
* Unit Tracking

// root потому что использовать в main
pub const RootAllocator = switch (builtin.mode) {
    .Debug => DebugAllocator(.{}),
    .ReleaseFast => FastAllocator(.{}),
    // т.д.
};

pub fn main() void {
    var allocator_instance: RootAllocator = .init;
    defer _ = allocator_instance.deinit();
    const allocator = allocator_instance.allocator();
}

const MyRootAllocator = switch (builtin.mode) {
    .Debug => DebugAllocator(.{ .stack_trace_frames = 10 }),
    .ReleaseSafe, .ReleaseFast => FastAllocator(.{ .verbose_log = true }), // выдумал
    .ReleaseSmall => FastAllocator(.{}),
};

pub fn main() void {
    // ...
}

Thanks to a colossal amount of work by Jacob Young, the x86_64 backend of Zig is now passing 101% of the behavior tests compared to the LLVM backend.

Or perhaps put another way, the LLVM backend is passing 99% of the behavior tests compared to the x86_64 backend 😉

Still a few more issues to tackle before it can be made the default, however.

Modernize the old async experiment.

Lowering is done using LLVM's Switched-Resume lowering, which allows Zig to fully manage memory, and avoid dynamic allocations. Similar to the old experiment, it is based on a runtime alloca, allowing calls and callees to be lowered independently.

working on a little something cool to enrich the tardy ecosystem 😊 it handles all I/O through the runtime, preventing the blocking that other libraries cause.

I just took a shower and I have an idea for how to get async await, and have them be actually good
