Windows support #977

FireFlyForLife · 2020-04-22T10:39:21Z

I believe cranelift is cross-platform. At least on windows.

However I only found Bash scripts for building with cargo for example. Is this a limitation, or am I missing something?

If a port from Bash to Batch (or something else like python) is needed I am of course happy to help!

I have been focusing on Linux and macOS. There are several places where Windows support is missing:

Abi::System: This is equivalent to Abi::C on x86_64 I think, but I am not sure.
.rlib: The rust-ar crate only supports BSD and Gnu style ar archives. I believe Windows uses a slightly different format.
The bash scripts, as you already noticed. (only config.sh, prepare.sh, test.sh and cargo.sh need to be ported. rustup.sh is just for me to switch to a new rustc version more easily. I haven't used flamegraph.sh in ages.)
Probably other things.

I did some experimentation on the windows_support branch, but it currently fails as I used bash to run the scripts and bash turns C:\ into /c/, which rustc doesn't recognize. As I don't use Windows, I have to wait for CI every time I try to fix something.

I don't think I will add Windows support soon, but PR's are of course welcome.

I got working support for cross compilation from Linux to MinGW on the wip_windows_support branch. For reference: see the comment thread starting at bytecodealliance/wasmtime#1510 (comment).

bjorn3 · 2020-05-26T10:47:36Z

The branch depends on bytecodealliance/wasmtime#1670 and an update to object 0.19.0.

FireFlyForLife · 2020-05-26T14:47:41Z

Wow amazing work, I will check this out soon!

bjorn3 · 2020-05-27T10:04:40Z

The branch now also depends on bytecodealliance/wasmtime#1767 for the object 0.19.0 update. (You need to merge both PR's into one branch)

bjorn3 · 2020-06-16T09:25:39Z

Updated the wip_windows_support branch for the latest Cranelift, which includes both bytecodealliance/wasmtime#1670 as well as bytecodealliance/wasmtime#1767.

cc #977

Patches in wip_windows_support:

backtrace-sys 0.1.37 giving gcc ice with mingw (newer backtrace versions use gimli instead)
~~Patch compiler-builtins to revert the "win64 128bit abi hack"~~
~~Patch PassMode::ByRef to not use ArgumentPurpose::StructArgument (unimplemented in Cranelift for WindowsFastcall)~~
~~Codegen ___chkstk, ___chkstk_ms and __alloca~~
Use x86_64-w64-mingw32-ranlib instead of plain ranlib (ranlib no longer used since Use builtin ranlib instead of running external ranlib #1067)
~~Missing TLS support in Cranelift for COFF/PE files ([Cranelift] Add COFF TLS support bytecodealliance/wasmtime#1885)~~ (Not actually used by libstd)
Disable the atomics shim, as pthreads is not available (fixed by Remove support for the old x86 Cranelift backend #1140)
Use the correct abi for calling 128bit int op intrinsics (9c98027 and 1122f42)
Implement WindowsFastcall abi for the new x64 Cranelift backend (x86-64 Windows fastcall ABI support. bytecodealliance/wasmtime#2678)

bjorn3 · 2021-01-31T13:36:47Z

9384af4 makes the examples link on windows. 9c943bf and 9164653 together add support for building the sysroot for windows. The examples and sysroot will still fail to build for windows though until the above todo list is fixed. a77ee9e is a workaround for these things when using the old x86 cranelift backend, but I won't merge that commit as it negatively affects other platforms too.

bjorn3 · 2021-02-21T11:10:12Z

9c98027 reduced the amount of used 128bit int intrinsics.

Building using both the MSVC and GNU toolchain should work fine. When compiling your own code for MSVC with cg_clif it will likely crash due to something not yet being implemented. With the GNU toolchain everything should work. Compiling code for the GNU toolchain using cg_clif is tested on CI. Compiling cg_clif itself for the MSVC toolchain worked fine in rust-lang/rust#81746. I am not sure why it gives undefined reference to `_Unwind_Resume' for you. That symbol is part of the exception unwinding mechanism that is used by gcc and rustc, so it should be defined.

Blues-star · 2021-06-05T16:21:07Z

I solved the trouble above, but when I want to translate the build.sh to buld.ps1, I found build.sh disallow building on windows

if [[ "$unamestr" == 'Linux' || "$unamestr" == "FreeBSD" ]]; then
   export RUSTFLAGS='-Clink-arg=-Wl,-rpath=$ORIGIN/../lib '$RUSTFLAGS
elif [[ "$unamestr" == 'Darwin' ]]; then
   export RUSTFLAGS='-Csplit-debuginfo=unpacked -Clink-arg=-Wl,-rpath,@loader_path/../lib -Zosx-rpath-install-name '$RUSTFLAGS
   dylib_ext='dylib'
else
   echo "Unsupported os $unamestr"
   exit 1

Does it mean I can not build it on windows ? and how to use cg_clif on windows?

bjorn3 · 2021-06-05T16:28:28Z

The build system doesn't have support for Windows yet. The main changes required to work on windows are likely to change ln target/$CHANNEL/*rustc_codegen_cranelift* "$target_dir"/lib to have "$target_dir"/bin as target instead of "$target_dir"/lib and have an empty case for windows in the if statement you mentioned. Windows doesn't support rpaths, so the dll needs to be next to the binaries.

An update on the x86_64-windows-pc-msvc target:

We've introduced TLS support for the COFF file format in cranelift (bytecodealliance/wasmtime#4546).

The test.sh file was also moved into y.rs so that we can run windows tests.

Here's an update on the current status of the testsuite on MSVC (only showing failed tests):

`no_sysroot`

`build.mini_core`

`build.example`

Passes as long as we build mini_core (i.e. disable printf).

`jit.mini_core_hello_world`

Need to disable a printf call to run.

Once bytecodealliance/wasmtime#4747 lands, we are in pretty good shape for windows support. If anyone wants to test it out in the mean time, this branch enables pretty much everything that we need.

As mentioned in https://github.com/bjorn3/rustc_codegen_cranelift/issues/1249#issuecomment-1221358262 we are still missing JIT support, and its currently disabled in the testsuite.

I had a go at enabling the JIT tests, but it fails in jit.mini_core_hello_world.

It panics with: thread 'rustc' panicked at 'can't resolve symbol _ZN9mini_core8A_STATIC17hc53ef79cc689fdd5E', and it looks like its because the object crate does not enumerate dll exports so no symbols are ever registered. (this also looks like what is reported in #1197)

I checked with dumpbin.exe and the symbol is exported in the dll, so we should be good in that regard.

Edit: Tried to run the objdump example from the object crate in the current master branch, and it detects the symbols! But it looks like it uses file.symbols() instead of file.dynamic_symbols() like we use in the JIT.

Edit2: Opened gimli-rs/object#457

bytecodealliance/wasmtime#4747 Is merged! 🎉 . With that I think we should remove the MSVC check on y.rs and enable inline stackprobing for Windows once cranelift 0.88 lands (CC #1276 I guess?).

Additionally on my TODO list is adding MSVC to CI.

From here, follow up work is the following:

Testing test_bootstrap.sh
Testing test_rustc_tests.sh
The JIT needs some love, its crashing in std_example (see: https://github.com/bjorn3/rustc_codegen_cranelift/pull/1273#issue-1353291888)

Although I'm quite busy now so I might not get to these anytime soon.

This should be done now thanks to @afonso360.
