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)
33 # It assumes the following flags are set:
34 # CFLAGS Platform_file, Src_Dirs_I, Src_Dirs_V, SYSDEFS, AOUT, Jvm_Obj_Files
36 # -- D. Ungar (5/97) from a file by Bill Bush

39 # Instead, use "gmake" (or "gnumake") from the command line. --Rose
