  26 # It DOES NOT include the vm dependency info in order to be faster.
  27 # Its main job is to implement the incremental form of make lists.

  29 #   -builds and runs adlc via adlc.make
  30 #   -generates JVMTI source and docs via jvmti.make (JSR-163)
  31 #   -generate sa-jdi.jar (JDI binding to core files)
  32 
  33 # It assumes the following flags are set:
  34 # CFLAGS Platform_file, Src_Dirs_I, Src_Dirs_V, SYSDEFS, AOUT, Obj_Files
