zig fmt fails to canonicalize `@ptrCast` and `@alignCast`

[andrewrk]

Zig Version

0.15.0-dev.699+2543e2d97

Steps to Reproduce and Observed Behavior

pub fn example() void {
    const x: bool = @ptrCast(@alignCast(1));
    const y: bool = @alignCast(@ptrCast(1));
    _ = x;
    _ = y;
}

zig fmt test.zig

does nothing

Expected Behavior

Expected zig fmt to rewrite the file to either:

pub fn example() void {
    const x: bool = @ptrCast(@alignCast(1));
    const y: bool = @ptrCast(@alignCast(1));
    _ = x;
    _ = y;
}

or

pub fn example() void {
    const x: bool = @alignCast(@ptrCast(1));
    const y: bool = @alignCast(@ptrCast(1));
    _ = x;
    _ = y;
}

The builtins affected by this are:

• @ptrCast
• @alignCast
• @addrSpaceCast
• @constCast
• @volatileCast

Any nesting of those builtins should be canonicalized to some default order. I would suggest @ptrCast at the front, and then following the canonical order for cv qualifiers, which coincidentally matches the order of my list above:

@ptrCast(@alignCast(@addrSpaceCast(@constCast(@volatileCast(something)))))
