I have tried to disable all macho link tests and successfully built zig stage3. The patch I use is:

Now I got a lot of test failures. I am not sure if I should change the default code model in zig code (or whether it has anything to do with these failures). Hope it helps in any way.

I went on and gave a try to build ncdu with the resulting stage3 zig. It seems more problems ahead:

[felixonmars]

The first issue seems to be #3340 and could be worked around by removing the cfi_label line.

The second issue seems to require adding ucontect_t and relevant structs to std/os/linux/riscv64.zig

[RossComputerGuy]

@felixonmars The cfi_label fix should come in #18803.

On the otherhand, I was shared this patch which would fix this particular issue. I don't see a PR for this fix so one should probably be open.

The compiler and build system should issue a proper error for this rather than panicking.

@Vexu yeah, though the problem comes from https://github.com/ziglang/zig/blob/master/lib/std/Target.zig#L299. How would std be updated to prevent an unreachable inside the builder like this?

Target.Query should issue an error for invalid macos architecture.

Target.Query improvements are covered by #18876.
