# Usage:
#
# $(MAKE) -f buildtree.make ARCH=arch BUILDARCH=buildarch LIBARCH=libarch
#         GAMMADIR=dir OS_FAMILY=os VARIANT=variant
#
# The macros ARCH, GAMMADIR, OS_FAMILY and VARIANT must be defined in the
# environment or on the command-line:
#
# ARCH		- sparc, i486, ... HotSpot cpu and os_cpu source directory
# BUILDARCH     - build directory
# LIBARCH       - the corresponding directory in JDK/JRE
# GAMMADIR	- top of workspace
# OS_FAMILY	- operating system
# VARIANT	- core, compiler1, compiler2, or tiered
# HOTSPOT_RELEASE_VERSION - <major>.-b (11.0-b07)
# HOTSPOT_BUILD_VERSION   - internal, internal-$(USER_RELEASE_SUFFIX) or empty
# JRE_RELEASE_VERSION     - <major>.. (1.7.0)
#
# Builds the directory trees with makefiles plus some convenience files in
# each directory:
#
# Makefile	- for "make foo"
# flags.make	- with macro settings
# vm.make	- to support making "$(MAKE) -v vm.make" in makefiles
# adlc.make	-
# trace.make	- generate tracing event and type definitions
# jvmti.make	- generate JVMTI bindings from the spec (JSR-163)
# sa.make	- generate SA jar file and natives
#
# The makefiles are split this way so that "make foo" will run faster by not
# having to read the dependency files for the vm.
