25# top.make is included in the Makefile in the build directories.
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.
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)
32
33# It assumes the following flags are set:
34# CFLAGS Platform_file, Src_Dirs_I, Src_Dirs_V, SYSDEFS, AOUT, Jvm_Obj_Files
