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=$OBJROOT/SETUP/config 74set MASTER_CONF_DIR=. 75 76set DEF_SEED="" 77 78 79unset doconfig 80unset beverbose 81unset MACHINE 82unset profile 83unset SOC_CONFIG 84unset PLATFORM 85 86while ($#argv >= 1) 87 if ("$argv[1]" =~ -*) then 88 switch ("$argv[1]") 89 case "-c": 90 case "-config": 91 set doconfig 92 breaksw 93 case "-cpu": 94 if ($#argv < 2) then 95 echo "${prog}: missing argument to ${argv[1]}" 96 exit 1 97 endif 98 set MACHINE="$argv[2]" 99 shift 100 breaksw 101 case "-soc": 102 if ($#argv < 2) then 103 echo "${prog}: missing argument to ${argv[1]}" 104 exit 1 105 endif 106 set SOC_CONFIG="$argv[2]" 107 if (`echo $SOC_CONFIG | awk '{print substr($0,0,2)}'` == "vm") then 108 set DEF_AVP="-DSOC_IS_VIRTUALIZED" 109 else 110 set DEF_AVP="-USOC_IS_VIRTUALIZED" 111 endif 112 shift 113 breaksw 114 case "-platform": 115 if ($#argv < 2) then 116 echo "${prog}: missing argument to ${argv[1]}" 117 exit 1 118 endif 119 set PLATFORM="$argv[2]" 120 shift 121 breaksw 122 case "-d": 123 if ($#argv < 2) then 124 echo "${prog}: missing argument to ${argv[1]}" 125 exit 1 126 endif 127 set OBJDIR="$argv[2]" 128 shift 129 breaksw 130 case "-m": 131 if ($#argv < 2) then 132 echo "${prog}: missing argument to ${argv[1]}" 133 exit 1 134 endif 135 set MASTER_CONF_DIR="$argv[2]" 136 shift 137 breaksw 138 case "-s": 139 if ($#argv < 2) then 140 echo "${prog}: missing argument to ${argv[1]}" 141 exit 1 142 endif 143 set SOURCEDIR="$argv[2]" 144 shift 145 breaksw 146 case "-verbose": 147 set beverbose 148 breaksw 149 case "-p": 150 case "-profile": 151 set profile 152 breaksw 153 default: 154 echo "${prog}: ${argv[1]}: unknown switch" 155 exit 1 156 breaksw 157 endsw 158 shift 159 else 160 break 161 endif 162end 163 164if ($#argv == 0) set argv=(GENERIC) 165 166if (!
