# Top level gnumake file for hotspot builds
#
# Default is to build the both product images and construct an export dir.
#  The default export directory name is `pwd`/export-$(PLATFORM).
#
#   Use: 'gnumake help' for more information.
#
# This makefile uses the default settings for where to find compilers and
#    tools, and obeys the ALT_* variable settings used by the other JDK
#    workspaces.
#

# Expected/optional make variables defined on make command line:
#  LP64=1 or ARCH_DATA_MODEL=64 for 64bit build
#
# Expected/optional make variables or environment variables:
#  ALT_SLASH_JAVA             Location of /java or J:
#  ALT_BOOTDIR                Previous JDK home directory for javac compiler
#  ALT_OUTPUTDIR              Output directory to use for hotspot build
#  ALT_EXPORT_PATH            Directory to export hotspot build to
#  ALT_JDK_IMPORT_PATH        Current JDK build (only for create_jdk rules)
#  ALT_BUILD_WIN_SA           Building SA on Windows is disabled by default.
#                             Set ALT_BUILD_WIN_SA=1 to enable building SA on
#                             Windows.
# Version strings and numbers:
#  JDK_VERSION                Current JDK version (e.g. 1.6.0)
#  PREVIOUS_JDK_VERSION       Previous (bootdir) JDK version (e.g. 1.5.0)
#  FULL_VERSION               Full version string to use (e.g. "1.6.0-ea-b42")
#
# Version strings and numbers especially needed on Windows:
#  COOKED_JDK_UPDATE_VERSION  Just the update release number (e.g. 02)
#  COOKED_BUILD_NUMBER        Just the build number (e.g. 42)
#  JDK_MKTG_VERSION           Marketing JDK version (e.g. 6.0)
#  JDK_MAJOR_VERSION          Major number for version (e.g. 1) always 1?
#  JDK_MINOR_VERSION          Minor number for version (e.g. 6)
#  JDK_MICRO_VERSION          Micro number for version (e.g. 0)
