The cross compilation instrcutions are confusing

[Heath123]

Configuring rustc_codegen_gcc

• Set TARGET_TRIPLE="m68k-unknown-linux-gnu" in config.sh.
• Since rustc doesn't support this architecture yet, set it back to TARGET_TRIPLE="mips-unknown-linux-gnu" (or another target having the same attributes). Alternatively, create a target specification file (note that the arch specified in this file must be supported by the rust compiler).
• Set linker='-Clinker=m68k-linux-gcc'.
• Set the path to the cross-compiling libgccjit in gcc_path.
• Comment the line: context.add_command_line_option("-masm=intel"); in src/base.rs.
• (might not be necessary) Disable the compilation of libstd.so (and possibly libcore.so?).

I want to compile this for SuperH but I'm confused by these instructions. It says to change a setting in config.sh but then immediately change it to something else without running anything in between??? How is that different from just setting it to the second thing directly? Is there a step missing somewhere? Also when it says "having the same attributes" what does it mean? Which attributes?

[bjorn3]

Also when it says "having the same attributes" what does it mean? Which attributes?

The target configuration like what atomic sizes are supported, the pointer width, type alignments, ... Basically if a target doesn't have a target specification in rustc, you either have to write a target specification json file for it (or patch rustc to add a builtin target spec), or you have to pick a target rustc does support which is as close to the target you actually want to compile for as possible as any divergence can break the abi or cause compilation errors due to eg declaring features supported that aren't actually supported. If the C abi for your target doesn't match any of the existing architectures supported by rustc, you will have to modify rustc one way or another as rustc hard codes the abi calculation code. It doesn't allow specifying it in the target specification.

[Heath123]

Thanks, do you know how I should find out what to use for SuperH?

Also I still don't know the answer to the thing about changing a setting and putting it back immediately

[antoyo]

Also I still don't know the answer to the thing about changing a setting and putting it back immediately

The first set is here and the second is a bit below.
It's not exactly necessary to do that, but that allows to keep the conditional that sets the proper linker.

[Heath123]

Thanks, now I'm getting

So it's trying to use the wrong linker, how do I change that?

Edit: Never mind, I was using the wrong GCC path

$ find .. -name libgccjit.so
../gccbuild/build-gcc/gcc/libgccjit.so
../gcc-cross/lib/libgccjit.so

I was using the first one instead of the second

[Heath123]

I'm getting another error (sorry):

It looks like that symbol isn't in the shared library, did I build it wrong? I did
../gcc/./configure --target=sh3eb-elf --prefix=/home/heath/sh-rustc/gcc-cross --disable-nls --enable-languages=c,jit,c++ --without-headers --enable-host-shared --disable-multilib

[antoyo]

Your command looks good. You can also add --disable-bootstrap for a faster build.

Are you sure you're using the latest commit in my gcc fork?
This gcc_jit_function_add_attribute function was added in this commit.

I downloaded the GCC source from the GNU website as a tarball and applies the patches in the patches repo. I'll try building it from that repo instead

[antoyo]

Ah right. I forgot to update the patches repo recently, so there are a few patches missing. Sorry.

[Heath123]

I hope I'm not being too annoying but when I try to build your fork I get this error:

It seems like this might be to do with SuperH not supporting the bfloat16 format?

[antoyo]

Yeah, maybe try commenting this case and see if this works?

[Heath123]

I did a slightly different patch to set the size to 16 bits, then I got this:

  error occurred: Failed to find tool. Is `mips-linux-gnu-gcc` installed?

So I symlinked mips-linux-gnu-gcc to sh3eb-elf-gcc, but now I get this really long error

It looks like something to do with it being 32-bit? It seems to be trying to use a 32-bit pointer as a 64-bit integer

[antoyo]

Yeah, indeed, it looks like it wants to cast a 32-bit pointer to a 64-bit integer. I'll attempt to fix this issue soon.

[Heath123]

I think the issue is here:

rustc_codegen_gcc/src/context.rs

Lines 169 to 170 in 1bbee3e

	let isize_type = context.new_c_type(CType::LongLong);
	let usize_type = context.new_c_type(CType::ULongLong);

[Heath123]

How do I disable compilation of std so that I can compile things without #![no_std] for now?

[Heath123]

It also seems to be trying to use https://github.com/rust-lang/compiler-builtins, can it just use libgcc?
