I thought this script was supposed 26# to work even without a /etc/machine, but it doesn't... and this 27# is the easiest way out. 28# 29# 13-Mar-87 Mike Accetta (mja) at Carnegie-Mellon University 30# Added "romp_fpa.h" file to extra features for the RT. 31# [ V5.1(F7) ] 32# 33# 11-Mar-87 Mike Accetta (mja) at Carnegie-Mellon University 34# Updated to maintain the appropriate configuration features file 35# in the "machine" directory whenever the corresponding 36# configuration is generated. This replaces the old mechanism of 37# storing this directly in the <sys/features.h> file since it was 38# machine dependent and also precluded building programs for more 39# than one configuration from the same set of sources. 40# [ V5.1(F6) ] 41# 42# 21-Feb-87 Mike Accetta (mja) at Carnegie-Mellon University 43# Fixed to require wired-in cpu type names for only those 44# machines where the kernel name differs from that provided by 45# /etc/machine (i.e. IBMRT => ca and SUN => sun3); updated to 46# permit configuration descriptions in both machine indepedent 47# and dependent master configuration files so that attributes can 48# be grouped accordingly. 49# [ V5.1(F3) ] 50# 51# 17-Jan-87 Mike Accetta (mja) at Carnegie-Mellon University 52# Updated to work from any directory at the same level as 53# "conf"; generate configuration from both MASTER and 54# MASTER.<machine-type> files; added -cpu switch. 55# [ V5.1(F1) ] 56# 57# 18-Aug-86 Mike Accetta (mja) at Carnegie-Mellon University 58# Added -make switch and changed meaning of -config; upgraded to 59# allow multiple attributes per configuration and to define 60# configurations in terms of these attributes within MASTER. 61# 62# 14-Apr-83 Mike Accetta (mja) at Carnegie-Mellon University 63# Added -config switch to only run /etc/config without 64# "make depend" and "make". 65# 66###################################################################### 67 68set prog=$0 69set prog=$prog:t 70set nonomatch 71set OBJDIR=../BUILD 72set SOURCEDIR=. 73set CONFIG_DIR=$OBJROOT/SETUP/config 74set MASTER_CONF_DIR=. 75 76set DEF_SEED="" 77set DEF_EXCLAVES="-UMASTER_CONFIG_ENABLE_EXCLAVES" 78set DEF_SPTM="-UMASTER_CONFIG_ENABLE_SPTM" 79set DEF_BUILD="" 80set DEF_TAG="" 81 82 83unset doconfig 84unset beverbose 85unset MACHINE 86unset profile 87unset SOC_CONFIG 88unset PLATFORM 89 90while ($#argv >= 1) 91 if ("$argv[1]" =~ -*) then 92 switch ("$argv[1]") 93 case "-c": 94 case "-config": 95 set doconfig 96 breaksw 97 case "-cpu": 98 if ($#argv < 2) then 99 echo "${prog}: missing argument to ${argv[1]}" 100 exit 1 101 endif 102 set MACHINE="$argv[2]" 103 shift 104 breaksw 105 case "-soc": 106 if ($#argv < 2) then 107 echo "${prog}: missing argument to ${argv[1]}" 108 exit 1 109 endif 110 set SOC_CONFIG="$argv[2]" 111 if (`echo $SOC_CONFIG | awk '{print substr($0,0,2)}'` == "vm") then 112 set DEF_AVP="-DSOC_IS_VIRTUALIZED" 113 else 114 set DEF_AVP="-USOC_IS_VIRTUALIZED" 115 endif 116 shift 117 breaksw 118 case "-platform": 119 if ($#argv < 2) then 120 echo "${prog}: missing argument to ${argv[1]}" 121 exit 1 122 endif 123 set PLATFORM="$argv[2]" 124 shift 125 breaksw 126 case "-d": 127 if ($#argv < 2) then 128 echo "${prog}: missing argument to ${argv[1]}" 129 exit 1 130 endif 131 set OBJDIR="$argv[2]" 132 shift 133 breaksw 134 case "-m": 135 if ($#argv < 2) then 136 echo "${prog}: missing argument to ${argv[1]}" 137 exit 1 138 endif 139 set MASTER_CONF_DIR="$argv[2]" 140 shift 141 breaksw 142 case "-s": 143 if ($#argv < 2) then 144 echo "${prog}: missing argument to ${argv[1]}" 145 exit 1 146 endif 147 set SOURCEDIR="$argv[2]" 148 shift 149 breaksw 150 case "-verbose": 151 set beverbose 152 breaksw 153 case "-p": 154 case "-profile": 155 set profile 156 breaksw 157 case "-sptm": 158 set DEF_SPTM="-DMASTER_CONFIG_ENABLE_SPTM" 159 breaksw 160 default: 161 echo "${prog}: ${argv[1]}: unknown switch" 162 exit 1 163 breaksw 164 endsw 165 shift 166 else 167 break 168 endif 169end 170 171if ($#argv == 0) set argv=(GENERIC) 172 173if (!
