[RISC-V] Interpreter Test Fails

[clamp03]

Description

JIT/interpreter/InterpreterTester/InterpreterTester.sh fails on RISCV64 docker (qemu).

Reproduction Steps

This is what I just used to build runtime and tests. (There must be better build configurations. :) )

Build Runtime

ROOTFS_DIR=<ROOTFS_PATH> ./build.sh -cross -arch riscv64 -rc Checked -lc Release -hc Checked -s clr+libs -p:UseLocalAppHostPack=true --cmakeargs -DFEATURE_IBCLOGGER=true --bootstrap

Build Tests

ROOTFS_DIR=<ROOTFS_PATH> ./src/tests/build.sh -riscv64 -Checked -priority1 -cross -p:UseLocalAppHostPack=true -p:LibrariesConfiguration=Release -p:SelfContained=false -p:PublishSingleFile=false

It fails with the below error message, however it built InterpreterTests which I want to test.

/work/dotnet/riscv/runtime/.dotnet/sdk/11.0.100-preview.3.26170.106/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(546,5): error NETSDK1112: The runtime pack for Microsoft.NETCore.App.Runtime.linux-riscv64 was not downloaded. Try running a NuGet restore with the RuntimeIdentifier 'linux-riscv64'. [/work/dotnet/riscv/runtime/src/tests/Common/XUnitLogChecker/XUnitLogChecker.csproj]

Tested on riscv64 docker

*. I set up the docker container 2 years ago. I tried to set up a new one with the same instructions, but I failed.

cd artifacts/tests/coreclr/linux.riscv64.Checked/
export CORE_ROOT=$PWD/Tests/Core_Root/
DOTNET_TieredCompilation=0 ./JIT/interpreter/InterpreterTester/InterpreterTester.sh

Expected behavior

InterpreterTester test pass

Actual behavior

At first, I think it needs to update value 0 of gcInfoEncoder->SetStackBaseRegister(0) in src/coreclr/interpreter/compiler.cpp.

When I updated this, it crashes with other error message.

I can't investigate further, because gdb is not working well on my computer.

Thanks a lot for testing and instructions. I have the device, I will try to repro it soon.

It fails with the below error message, however it built InterpreterTests which I want to test.

Yup, testing infra (runtime as well as libs) is not compatible with --bootstrap machinery: #115622. I think it just needs setting up some properties to toggle it to use "live" artifacts instead of nuget package; rest is already in place. I think AI can figure out magic msbuild properties and spells faster than human, but my AI usage is overflowing with other things ATM, will try to save some quota for it next week or so. 😅
