With the same patch above, it seems that it is possible to compile zig2 successfully but failed in stage 3.

it seems that zig itself requires fstat to work.

However, loongarch64 does not have fstat/fstatat syscall support and only has statx syscall.

Maybe we should add a translation layer for fstat/fstatat that uses statx underhood?

nektro commented 7 months ago

However, loongarch64 does not have fstat/fstatat syscall support

is there a specific reason for this or is it because its simply not implemented yet in the kernel since loongarch64 is such a relatively new architecture?

Check the syscalls here.

It seems that it is not implemented in Linux kernel intentionally. And golang has an emulation implementation of fstatat with statx.

yxd-ym commented 7 months ago

With current patch, I think I have implemented most of the loongarch64 things needed for zig std lib.

https://github.com/yxd-ym/zig-bootstrap/pull/1

$ CMAKE_GENERATOR=Ninja CC=/usr/bin/clang CXX=/usr/bin/clang++ ./build loongarch64-linux-gnu loongarch64

The overflow happens on stack element 18 where num=12297829382473034410. It seems that the builtin function @intFromBool is not implemented.

I guess things like zig/src/arch/loongarch64 need to be implemented like other CPU architectures (e.g. zig/src/arch/aarch64 and zig/src/arch/riscv64) next.

This has been fixed.

And now the error is zig2 failed to build libunwind.

Disabled the macro _LIBUNWIND_IS_NATIVE_ONLY and it is OK to build libunwind.

The next problem is that ld.lld having error doing relocation when linking zig binary.

yxd-ym commented 7 months ago

Managed to replace ld.lld with mold for the command that linking zig binary. Now I have a working zig stage3 binary I guess.

yxd-ym commented 7 months ago

With the patch now it is possible to build a stage3 zig binary with command

$ CMAKE_GENERATOR=Ninja CC=/usr/bin/clang CXX=/usr/bin/clang++ ./build loongarch64-linux-gnu loongarch64

With this stage3 zig binary, there is still some problem:

Now have the same issue as

@yxd-ym so only the LLVM 19 upgrade remains now?

yxd-ym commented 1 week ago

so only the LLVM 19 upgrade remains now?

For successfully bootstraping a loongarch64 zig binary, YES.

However, for a workable loongarch64 zig binary, I'm still looking into this problem.

https://github.com/ziglang/zig-bootstrap/issues/164#issuecomment-2300478462

It seems that the options struct parameter passed by value to function ZigLLVMTargetMachineEmitToFile is not handled correctly.

CPP declaration of this function:

ZIG_EXTERN_C bool ZigLLVMTargetMachineEmitToFile(
    LLVMTargetMachineRef targ_machine_ref,
    LLVMModuleRef module_ref,
    char **error_message,
    struct ZigLLVMEmitOptions options
);

zig binding function:

extern fn ZigLLVMTargetMachineEmitToFile(
    T: *TargetMachine,
    M: *Module,
    ErrorMessage: *[*:0]const u8,
    options: EmitOptions,
) bool;

So I guess this is a struct function parameter passing by value ABI problem? Currently I have no idea how to solve this problem yet. Any suggestions?

I'll try to take a look at this soon.

It's most likely just down to missing sret and byval vs byref handling for LoongArch in Zig's LLVM backend. I'll take a closer look later today. Lots of TODOs in that code for other architectures too.

yxd-ym commented 1 week ago

With https://github.com/ziglang/zig/pull/21251

we are able to bootstrap a loongarch64 zig to compile hello world c program and zig program.
