NativeAOT-LLVM: Compile fails due to invalid cast error #2555

Closed PJB3005 closed 2 months ago

PJB3005 commented 2 months ago

I tried to compile Space Station 14's client as a test run, if only just to get a ballpark of how large the final wasm binary would be. I know full-well there's no chance in hell it's going to work just like this, but while compiling the code on Release the following error did crop up:

EXEC : error : Invalid cast (Producer: 'LLVM17.0.4' Reader: 'LLVM 18.0.0git') [E:\.nuget\microsoft.dotnet.ilcompiler.llvm\9.0.0-alpha.1.24173.1\build\ExecWrapper.proj]
  1 error generated.

Reproduction branch:

Note that the project makes use of submodules: the RobusToolbox submodule in the main repo (first link) needs to be updated to point to the second link.

Error occurs when doing dotnet publish -r wasi-wasm -c Release /p:UseAppHost=false inside Content.Client on those branches.

NativeAOT-LLVM version: 9.0.0-alpha.1.24173.1 Emscripten SDK version: 3.1.47 WASI SDK version: 22.0

Fixed in #2556. In have confirmed also that the project compiles successfully after that.
