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