I found this during the work of JDK-8302139.

This test bug means that multiple tests are ignored on intel machines. We have to replace "sse4_1" with "sse4.1".

As [~kvn] said:

sse4_1 comes from /proc/cpuinfo. sse4.1 is in CPU_FEATURE_FLAGS and produced by VM output. IR framework gets info from WHITE_BOX.getCPUFeatures() which calls VM_Version::features_string(). So you are right tests should use sse4.1

grep "sse4" test/hotspot/jtreg/compiler/ -r

When I quickly ran one of them, I got this reported back to me:
