Description Alexander Köplinger [MSFT] 2017-03-13 11:45:58 UTC
Run https://github.com/mono/coreclr/blob/c7da48acf72c40c0c0ed1a80ebfacea21bb3a271/tests/src/JIT/SIMD/Ctors.cs on Mono master/814d37f556d24, it returns exit code zero. Mono 4.8 returns exit code 100 (the correct one for a "passed" coreclr test) -> Regression

Run https://github.com/mono/coreclr/blob/c7da48acf72c40c0c0ed1a80ebfacea21bb3a271/tests/src/JIT/SIMD/CreateGeneric.cs on Mono master, it crashes with:

> get_simd_vreg:: could not infer source simd vreg for op
> iconst R154 <- [49]
>* Assertion: should not be reached at simd-intrinsics.c:836

Mono 4.8 returned a type load exception, so not really a regression :)
