@tannergooding is this from dotnet/runtime@c65d921 ? range is dotnet/runtime@745b776...c8e4f2c

[tannergooding]

It could be, but its a bit surprising if that's the case?

Maybe this is a case where the jiterpreter needs to be updated to handle it as well, CC. @kg ?

[kg]

Adding interp intrinsics without updating the jiterpreter will usually regress performance, yes.

[tannergooding]

Adding interp intrinsics without updating the jiterpreter will usually regress performance, yes.

I see, that's a bit unfortunate. I'll keep it in mind for future PRs, however.

Is there something we can do in the meantime to improve the handling? I don't see anything in https://github.com/dotnet/runtime/blob/main/src/mono/browser/runtime/jiterpreter-trace-generator.ts or related files that looks to handle the concept of "bitcasting". However, I don't believe WASM needs to track the actual type and the PackedSimd support instead interprets the 128-bit value based on the opcode its passed into so perhaps we just need to handle it as a "no-op" and simply return the input value untouched?

Based on other code, this looks like it'd be roughly:

append_ldloc(builder, getArgU16(ip, 2), WasmOpcode.PREFIX_simd, WasmSimdOpcode.v128_load);
append_simd_store(builder, ip);

handled as part of emit_simd_2 (which it looks like means it has two operands on the stack where arg 1 is the destination and arg 2 is the source)?
