See: https://elixir.bootlin.com/llvm/llvmorg-18.1.8/source/llvm/lib/Target/LoongArch/LoongArchTargetMachine.cpp#L74

LLVM 18 only supports

  • small
  • medium
  • large

code model on loongarch64.

And it seems to remain the same in LLVM 19.
See: https://elixir.bootlin.com/llvm/llvmorg-19.1.0-rc3/source/llvm/lib/Target/LoongArch/LoongArchTargetMachine.cpp#L83

I have tried different values, but medium seems to be the only one supported for both loongarch64-linux-gnu and loongarch64-linux-musl to have a debuggable loongarch64 zig built.

Also see: ziglang/zig-bootstrap#164 (comment)

Here is where the default code model is selected by the compiler frontend:

zig/src/Package/Module.zig

Lines 222 to 226 in 16d7480

const code_model = b: {
if (options.inherited.code_model) |x| break :b x;
if (options.parent) |p| break :b p.code_model;
break :b .default;
};

Here, you can observe that the selected backend is the LLVM backend and default to medium.

I see. So setting it explicitly is not needed? Then I will close this.

What I mean is that your patch should edit these lines instead of build.zig.

Has an upstream LLVM issue been filed for whatever it is that's causing this to be necessary?

llvm/llvm-project#72514 (comment)

So my guesses are

  • If we don't explicitly set -mcmodel, llvm will use small by default.
  • However, for zig, we need to explicitly set it to medium like chromium's case to avoid relocation overflow problem.

I'm not sure whether this is correct.

Can you go into detail regarding the R_LARCH_B26 problem you mentioned? Just trying to understand why the default code model is not sufficient for Zig. Is it just that the Zig binary is so big that the relocations in the default code model don't have enough range?

Is it just that the Zig binary is so big that the relocations in the default code model don't have enough range?

I think this is the reason of the above error.

Ok, so it's an issue specific to building the zig binary because it's so big. Then editing build.zig seems to be the right call to me; editing src/Package/Module.zig would, AFAICT, mean we're imposing a larger-than-necessary default code model on all binaries. What do you think @andrewrk?

It seems like any project could hit this limitation if its code grows beyond a certain threshold.
Would it be possible to add some kind of detection, so that Zig could inform the user "the resulting binary is too large for the selected code model, use -mcmodel=(medium|large)"?

It seems like any project could hit this limitation if its code grows beyond a certain threshold.

Yes, but that's true of code models on all architectures, not just on LoongArch. It's a trade-off between code size & performance vs upper limit on binary size. Each target has a different default code model - LoongArch just happens to have a relatively small one.

Would it be possible to add some kind of detection

You can't know that you've hit the binary size limit until link time. That said, a linker could probably suggest trying a larger code model when running into relocation range issues.

LGTM; as I noted here, I don't think this is something that requires backend changes - it's just that the zig binary in particular is very large.
