    Description

      PPC64 has an implementation of a "stop" function to be used in assembler code. Purpose is to stop execution of the JVM with an hs_err file.
      It can also be used to provide an error message. This is goal of JDK-8230552.
      Unfortunately, the current implementation generates large code which is not desirable. It can be implemented based on trap instructions.
      In addtion to that, the current implementation contains features which have not proven to be useful, so cleanup would be nice (e.g. stop id).
