This works fine in 9 so I'm not exactly sure what's different.

Steps to reproduce:

1) Find a machine without AVX support
2) Build jdk10/hs
3) Run:

$ sh hotspot/test/compiler/aot/scripts/build-jdk.vm-modules.sh

4) Run:

$ ./build/linux-x86_64-normal-server-release/images/jdk/bin/java -XX:+UnlockDiagnosticVMOptions -XX:+UseAOTStrictLoading -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler -XX:+BootstrapJVMCI -XX:-TieredCompilation -version

The crash happens at the addpd instruction:
