The regressions should be resolved by the change introduced in https://github.com/dotnet/runtime/pull/91813. If some of the microbenchmarks are still regressed after the change, I will reopen the issue and investigate further.

Thank you @kotlarmilos. Now I can reproduce the regression introduced in https://github.com/dotnet/runtime/pull/89364/files locally for AOT-llvm as well.

matouskozak on Sep 4, 2023

Regression could be introduced in dotnet/runtime#89364.

Seems to me like it’s an issue with Mono if it’s not able to ignore unaligned when it’s not necessary (as in on platforms with unaligned reads or when it knows the source ref is correctly aligned).

The artifacts are downloaded from https://dev.azure.com/dnceng//_apis/resources/Containers/14759805?itemPath=LinuxMonoAOTx64&isShallow=true&api-version=4.1-preview.4.

The command for building the runtime:

./build.sh -ci -arch x64 -os linux -cross -s mono+libs+host+packs -c Release /p:BuildMonoAOTCrossCompiler=true /p:MonoLibClang="/usr/local/lib/libclang.so.16" /p:AotHostArchitecture=x64 /p:AotHostOS=linux

I checked the generated code for Vector.LessThan. It hasn’t changed comparing before and after https://github.com/dotnet/runtime/pull/89364

This is probably caused by other parts of the generated code. Intrinsify Unsafe.BitCast could probably help.
