# Usage:
#
# $(MAKE) -f buildtree.make SRCARCH=srcarch BUILDARCH=buildarch LIBARCH=libarch
#         GAMMADIR=dir OS_FAMILY=os VARIANT=variant OPENJDK_TARGET_CPU_ENDIAN=endianness
#
# The macros ARCH, GAMMADIR, OS_FAMILY and VARIANT must be defined in the
# environment or on the command-line:
#
# ARCH		- sparc, i486, ... HotSpot cpu and os_cpu source directory
# BUILDARCH     - build directory
# LIBARCH       - the corresponding directory in JDK/JRE
# GAMMADIR	- top of workspace
# OS_FAMILY	- operating system
# VARIANT	- core, compiler1, compiler2, or tiered
# HOTSPOT_RELEASE_VERSION - <major>.<minor>-b<nn> (11.0-b07)
# HOTSPOT_BUILD_VERSION   - internal, internal-$(USER_RELEASE_SUFFIX) or empty
# JRE_RELEASE_VERSION     - <major>.<minor>.<micro> (1.7.0)
# OPENJDK_TARGET_CPU_ENDIAN - target endianness: 'big'/'little'. Used to differentiate
#                   the architecture flavor for PowerPC64
# 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
# env.[ck]sh	- environment settings
# test_gamma	- script to run the Queens program
# 
# The makefiles are split this way so that "make foo" will run faster by not
# having to read the dependency files for the vm.
