# 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
#
#
# CPU VARIANTS
# To compile part of the source tree for a CPU variant, first a tag must be
# defined with which archive directory names are modified. In addition several
# variables must be defined for each CPU variant build. Refer to the example
# further below for more details. Note that CPU variant builds are normaly
# started automatically at the end of the corresponding generic CPU build.
# 
#
# 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.

## CPU variants builds
#
# For CPU variants builds, the name of the directory(ies) where archives are 
# installed is appended with a unique tag defined by LIB_DIR_TAG. The make
# variable CPU_VARIANT_LIST define the whole list of these CPU variant tags
# and should be updated everytime a new CPU variant build is introduced. For
# instance:
#	CPU_VARIANT_LIST = _cpuVariant1 _cpuVariant2 _cpuVariant3

#	  to one of the item defined in CPU_VARIANT_LIST. For instance:
#	  	VX_ARCHIVE_LIST_cpuVariant1 = libarch.a libdrv.a
#
#	- CPU_VARIANT_CPU_TOOL_LIST$(LIB_DIR_TAG): this is the list of
#	  CPU/TOOL combination(s) for which the CPU variant build must be
#	  run. For instance:
#		CPU_VARIANT_CPU_TOOL_LIST_cpuVariant2 = MIPS32diab MIPS64diab
