# DESCRIPTION
# This file contains the makefile rules to select subdirectories that contain
# sources for building the VxWorks runtime archive and builds them.
#
# Some architecures support only one toolchain family (either GNU or DIAB). 
# The toolchain supported is defined by VENDOR_DEFAULT below. 
# For instance to build the source tree for the solaris simulator which supports
# only the GNU toolchain, you should issue the following commands:
#		> cd $WIND_BASE/target/src
#		> make CPU=SIMSPARCSOLARIS TOOL=gnu
#
# Other architecures support both toolchain families (GNU and DIAB).
# However most of the VxWorks source code under $(WIND_BASE)/target/src/
# is compiled with only one toolchain family (either GNU or DIAB). This
# default toolchain is defined again by VENDOR_DEFAULT. Nevertheless part of
# the VxWorks source tree must still be built with the secondary toolchain
# family. This dual build is accomplished in two passes.
#
# For instance to build the source tree for CPU=PPC604 which supports both
# GNU and DIAB, the following commands must be issued:
#		> cd $WIND_BASE/target/src
#		> make CPU=PPC604 TOOL=diab
#		> make CPU=PPC604 TOOL=gnu
#
#
#
# FOR TESTING PURPOSES
# If a dual build of the source tree should not be performed for a CPU type
# which by default supports both toolchain families, the value of DUAL_BUILD
# must be overwritten on the command line.
# For instance to build successfuly the entire source tree for CPU=PPC604 with
# the DIAB toolchain despite it is not the default toolchain for this 
# architecture, issue the following commands:
#		> cd $WIND_BASE/target/src
#		> make CPU=PPC604 TOOL=diab DUAL_BUILD=false
#
# You may need to build the entire source tree with both toolchain families
# (GNU and DIAB). Every source file must be compiled with both toolchains
# and the resulting objects stored in a different locations. As above 
# DUAL_BUILD must be set to false and in addition the COMMON_DIR variable
# must be overwritten and set to false:
#		> cd $WIND_BASE/target/src
#		> make CPU=PPC604 TOOL=diab DUAL_BUILD=false COMMON_DIR=false
#		> make CPU=PPC604 TOOL=gnu DUAL_BUILD=false COMMON_DIR=false
#
# INTERNAL
# The REAME.txt file under $(WIND_BASE)/target/src/ should be updated whenever
# this file is modified, if appropriate.
