Incremental compilation

13

## How do I try it? **TL;DR:** `zig build --watch -fincremental --prominent-compile-errors`, either targeting `x86_64-linux` with the self-hosted backend, or just not emitting a binary (i.e. `-fno-emit-bin`). The easiest way...

The Zig compiler currently fails to handle OOM correctly in many cases. Ideally, if semantic analysis OOMs, we would like to report an error message in `zcu.failed_analysis`. There are two...

Provide a configuration option to use incremental compilation for build-on-save

3

After ziglang/zig#21063 is merged, the Zig compiler is able to perform certain incremental updates correctly. There's still a ways to go before it's generally usable, but `-fno-emit-bin` builds will be...

Replace `std.builtin.CallingConvention` with a tagged union, eliminating `@setAlignStack`

TODO: PR message

This PR resolves #23959 by first introducing a helpful compiler feature for debugging incremental compilation, and then using it to find the bug in that issue. A corresponding incremental test...

Proposal: add `@memCast` for a class of safe pointer casts

3

## Background After the merge of #22706 and #23919, you can now `@ptrCast` to a slice where the operand is *any* slice or single-item pointer. The idea, broadly speaking, is...

`std.Build.Step.Fmt` handles paths incorrectly

1

`std.Build.Step.Fmt` takes a `[]const []const u8` to represents its paths. They are interpreted as relative to the step's owner `Build`'s build root. This is inappropriate. They should likely be relative...

### Zig Version 0.15.0-dev.552+bc2f7c754 ### Steps to Reproduce and Observed Behavior * Create a `std.process.Child` with `.init` * Try to use its `stdout_behavior`/`stderr_behavior`/`stdin_behavior` to specify an existing `std.fs.File` as the...

Compilation: add missing link file options to cache manifest

I unintentionally closed #23891 while pruning branches; this is the exact same diff. Resolves: #23869

Proposal: disallow referencing errors with `ErrorSet.Foo` in favour of `error.Foo`

8

Error values in Zig can be constructed in three ways: * `@errorFromInt`. This is just a low-level primitive which is useful in niche scenarios (usually ABI stuff, such as passing...
