  26 # It DOES NOT include the vm dependency info in order to be faster.
  27 # It's main job is to implement the incremental form of make lists.
  28 # It also:
  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)

  34 # CFLAGS Platform_file, Src_Dirs, SYSDEFS, AOUT, Jvm_Obj_Files
