# 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>.<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)

#

# 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	- 

# 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.
