        public static java.util.List<java.lang.String> getCompileCommandFiles​(java.util.List<java.lang.String> command)
        Parameters:
        command - command arguments list
        Returns:
        the compiler hint files specified by the command

      • addCompilerHints

        public static void addCompilerHints​(java.util.List<java.lang.String> command)
        We need to generate a compiler hints file such that it includes:
        • No compile command files are specified and no .hotspotrc file is available, then do JMH hints only
        • No compile command files are specified and .hotspotrc file is available, then do JMH hints + .hotspotrc
        • 1 to N compile command files are specified, then do JMH hints + all specified hints in files

        This is a departure from default JVM behavior as the JVM would normally just take the last hints file and ignore the rest.

        Parameters:
        command - all -XX:CompileCommandLine args will be removed and a merged file will be set

      • getReaders

        protected java.util.List<java.io.Reader> getReaders()
        Helper method for creating a Reader for the list file.
        Returns:
        a correct Reader instance
