# top.make is included in the Makefile in the build directories.
# It DOES NOT include the vm dependency info in order to be faster.
# Its main job is to implement the incremental form of make lists.

# -builds and runs adlc via adlc.make
# -generates JVMTI source and docs via jvmti.make (JSR-163)
# -generate sa-jdi.jar (JDI binding to core files)
# It assumes the following flags are set:
# CFLAGS Platform_file, Src_Dirs_I, Src_Dirs_V, SYSDEFS, AOUT, Obj_Files
# -- D. Ungar (5/97) from a file by Bill Bush
# Don't override the built-in $(MAKE).
