ciReplay: fails to resolve @SignaturePolymorphic methods in replay data

XMLWordPrintable

    • b14

      During compilation replay data parsing, VM fails to resolve signature-polymorphic method entries.

      For example:
      ciMethod java/lang/invoke/MethodHandle invokeBasic (Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object; 1 1 1 0 -1
      ciMethod java/lang/invoke/MethodHandle invokeBasic (Ljava/lang/Object;)Ljava/lang/Object; 1 1 1 0 -1
      ciMethod java/lang/invoke/MethodHandle invokeBasic (Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object; 1 1 1 0 -1
      ciMethod java/lang/invoke/MethodHandle invokeBasic (Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)V 1 1 1 0 -1
      ciMethod

      It's one of the blockers to successfully replay compilations of methods which use JSR292.

      I see 2 possible solutions:
          1) don't dump signature-polymorphic methods into replay file (it seems there's no useful info there anyway)
          2) try to resolve, but as a special-case (ignore method signature)
