26 # Usage:
27 #
28 # $(MAKE) -f buildtree.make SRCARCH=srcarch BUILDARCH=buildarch LIBARCH=libarch
29 # GAMMADIR=dir OS_FAMILY=os VARIANT=variant
30 #
31 # The macros ARCH, GAMMADIR, OS_FAMILY and VARIANT must be defined in the
32 # environment or on the command-line:
33 #
34 # ARCH - sparc, i486, ... HotSpot cpu and os_cpu source directory
35 # BUILDARCH - build directory
36 # LIBARCH - the corresponding directory in JDK/JRE
37 # GAMMADIR - top of workspace
38 # OS_FAMILY - operating system
39 # VARIANT - core, compiler1, compiler2, or tiered
40 # HOTSPOT_RELEASE_VERSION - <major>.<minor>-b<nn> (11.0-b07)
41 # HOTSPOT_BUILD_VERSION - internal, internal-$(USER_RELEASE_SUFFIX) or empty
42 # JRE_RELEASE_VERSION - <major>.<minor>.<micro> (1.7.0)
43 #
44 # Builds the directory trees with makefiles plus some convenience files in
45 # each directory:
46 #
47 # Makefile - for "make foo"
48 # flags.make - with macro settings
49 # vm.make - to support making "$(MAKE) -v vm.make" in makefiles
50 # adlc.make -
51 # jfr.make - generate jfr event and type definitions
52 # jvmti.make - generate JVMTI bindings from the spec (JSR-163)
53 # sa.make - generate SA jar file and natives
54 #
55 # The makefiles are split this way so that "make foo" will run faster by not
56 # having to read the dependency files for the vm.
