The test compiler/vectorapi/reshape/TestVectorReinterpret.java fails on the ppc64(le) based platforms.
Example :

 
compiler.lib.ir_framework.driver.irmatching.IRViolationException: There were one or multiple IR rule failures. Please check stderr for more information.

Reason is missing optimization on ppc64(le) platforms. The related JEP only handled aarch64 and x86_64 :
