When AOTing the System.Numerics.Vectors.Tests assembly on main, clang instruction selection crashes when compiling PackedSimd.Shuffle, see https://gist.github.com/kg/450e9f560df6ca5c82c38eff1902a29b . If I remove PackedSimd.Shuffle entirely from the .cs files the AOT succeeds.

Can't reproduce this, what is the command line ?

/home/kate/Projects/dotnet-runtime-wasm/dotnet.sh build /bl /t:Test /p:TargetOS=browser /p:TargetArchitecture=wasm /p:Configuration=Release /home/kate/Projects/dotnet-runtime-wasm/src/libraries/System.Numerics.Vectors/tests/System.Numerics.Vectors.Tests.csproj /p:EnableAggressiveTrimming=true /p:RunAOTCompilation=true /p:WasmEnableSIMD=true

Radek appears to have hit it before as well, see llvm/llvm-project#55559 . Might have something to do with OS packages or be a nondeterminism thing. Can't reproduce it on main right now, but I've blown away my checkout multiple times since then - will see if I can reconstruct it.

Hit this again trying to AOT a different test suite.
