Some tests fail with:

# Internal Error (/home/rkennke/src/openjdk/jdk-jdk/src/hotspot/cpu/x86/assembler_x86.cpp:3819), pid=5051, tid=5055
# Error: assert(VM_Version::supports_sse4_1()) failed

When running hotspot/jtreg:tier1 on my ThreadRipper 1950X box. On Intel box, this works fine. It looks like it attempts to generate fast_sha1 stubs, which use Assembler::pinsrd() but then runs into supports_sse4_1().

I suspect the issue is two-fold:
- It should not generate that stub, using that instructions, on CPU that really do not support the required SSE4.1 instruction set.
- It should detect that TR CPU does, infact, support SSE 4.1

The failing tier1 tests are:
