The Compiler Control added by https://openjdk.org/jeps/165 improved the way to control the C1 and C2 JVM compilers. It needs to be extended to handle JVMCI compilers such as Graal.

In the current state, a number of the tests added by JEP 165 test fail when libgraal is enabled. For example, compiler/compilercontrol/directives/ExcludeTest.java fails with:

Checking expected compilation state: {
  method: public void compiler.compilercontrol.share.pool.sub.Klass.method(int,java.lang.String[],java.lang.Integer,byte[],double[][])
  compile [Optional.empty, Optional.empty]
  force_inline [Optional.empty, Optional.empty]
  dont_inline [Optional.empty, Optional.empty]
  log Optional.empty
  print_assembly Optional.empty
  print_inline Optional.empty
}
Checking expected compilation state: {
  method: public void compiler.compilercontrol.share.pool.sub.Klass.method()
  compile [Optional.empty, Optional[false]]
  force_inline [Optional.empty, Optional[false]]
  dont_inline [Optional.empty, Optional[true]]
  log Optional.empty
  print_assembly Optional.empty
  print_inline Optional.empty
}
