For example "athlon-pc-freebsd3.5" is validated using 37# "i386-pc-freebsd3.5". 38# 39# Any canonicalizations made by configfsf.sub are preserved. For example 40# given "athlon-linux", configfsf.sub is called with "i386-linux" and will 41# give back "i386-pc-linux-gnu". "athlon" is then reinstated, so we print 42# "athlon-pc-linux-gnu". 43 44 45# Expect to find configfsf.sub in the same directory as this config.sub 46configfsf_sub="`echo \"$0\" | sed 's/config.sub$/configfsf.sub/'`" 47if test "$configfsf_sub" = "$0"; then 48 echo "Cannot derive configfsf.sub from $0" 1>&2 49 exit 1 50fi 51if test -f "$configfsf_sub"; then 52 : 53else 54 echo "$configfsf_sub not found" 1>&2 55 exit 1 56fi 57 58# Always run configfsf.sub with $SHELL, like autoconf does for config.sub 59SHELL=${CONFIG_SHELL-/bin/sh} 60 61# Identify ourselves on --version, --help, etc 62case "$1" in 63"" | -*) 64 echo "(GNU MP wrapped config.sub)" 1>&2 65 $SHELL $configfsf_sub "$@" 66 exit 67 ;; 68esac 69 70given_full="$1" 71given_cpu=`echo "$given_full" | sed 's/-.*$//'` 72given_rest=`echo "$given_full" | sed 's/^[^-]*//'` 73 74 75# Aliases for GMP extras 76case "$given_cpu" in 77 # configfsf.sub turns p5 into i586, instead use our exact cpu type 78 p5 | p54) given_cpu=pentium ;; 79 p55) given_cpu=pentiummmx ;; 80 81 # configfsf.sub turns p6, pentiumii and pentiumiii into i686, instead use 82 # our exact cpu types 83 p6) given_cpu=pentiumpro ;; 84 pentiumii) given_cpu=pentium2 ;; 85 pentiumiii) given_cpu=pentium3 ;; 86esac 87given_full="$given_cpu$given_rest" 88 89 90# GMP extras and what to use for the config.sub test 91case "$given_cpu" in 92itanium | itanium2) 93 test_cpu=ia64 ;; 94pentium | pentiummmx | pentiumpro | pentium[234] | k[56] | k6[23] | athlon | viac3*) 95 test_cpu=i386 ;; 96power[2-9] | power2sc) 97 test_cpu=power ;; 98powerpc401 | powerpc403 | powerpc405 | \ 99powerpc505 | \ 100powerpc601 | powerpc602 | \ 101powerpc603 | powerpc603e | \ 102powerpc604 | powerpc604e | \ 103powerpc620 | powerpc630 | powerpc970 | \ 104powerpc740 | powerpc7400 | powerpc7450 | powerpc750 | \ 105powerpc801 | powerpc821 | powerpc823 | powerpc860 | \ 106powerpc64) 107 test_cpu=powerpc ;; 108sparcv8 | supersparc | microsparc | \ 109ultrasparc | ultrasparc2 | ultrasparc2i | ultrasparc3 | ultrasparct1) 110 test_cpu=sparc ;; 111sh2) 112 test_cpu=sh ;; 113 114*) 115 # Don't need or want to change the given name, just run configfsf.sub 116 $SHELL $configfsf_sub "$given_full" 117 if test $? = 0; then 118 exit 0 119 else 120 echo "(GNU MP wrapped config.sub, testing \"$given_full\")" 121 exit 1 122 fi 123esac 124 125 126test_full="$test_cpu$given_rest" 127canonical_full=`$SHELL $configfsf_sub "$test_full"` 128if test $? = 0; then 129 : 130else 131 echo "(GNU MP wrapped config.sub, testing \"$given_full\" as \"$test_full\")" 132 exit 1 133fi 134 135canonical_rest=`echo "$canonical_full" | sed 's/^[^-]*//'` 136echo "$given_cpu$canonical_rest" 137exit 0 138 139 140 141# Local variables: 142# fill-column: 76 143# End: 144
