annotate src/share/vm/c1/c1_globals.hpp @ 7062:8c5333c80cfd
increased CompileThreshold to increase reliability of profiling information
increased InitialCodeCacheSize to fit the bootstrapping
added flag -XX:GraalClassPath to allow providing a .jar or .zip file that contains all Graal classes
added support for the flag -XX:TraceCompilationPolicy to the Graal-specific compilation policy
