The general theme is to verify that common Makefile rules 34# have been used to build these objects. Typical failures occur when Makefile 35# rules are re-invented rather than being inherited from "cmd/lib" Makefiles. 36# 37# As always, a number of components don't follow the rules, and these are 38# excluded to reduce this scripts output. Pathnames used for this exclusion 39# assume this script is being run over a "proto" area. The -a (all) option 40# skips any exclusions. 41# 42# By default any file that has conditions that should be reported is first 43# listed and then each condition follows. The -o (one-line) option produces a 44# more terse output which is better for sorting/diffing with "nightly". 45# 46# NOTE: missing dependencies, symbols or versions are reported by running the 47# file through ldd(1). As objects within a proto area are built to exist in a 48# base system, standard use of ldd(1) will bind any objects to dependencies 49# that exist in the base system. It is frequently the case that newer objects 50# exist in the proto area that are required to satisfy other objects 51# dependencies, and without using these newer objects an ldd(1) will produce 52# misleading error messages. To compensate for this, the -d option (or the 53# existence of the CODEMSG_WS/ROOT environment variables) cause the creation of 54# alternative dependency mappings via crle(1) configuration files that establish 55# any proto shared objects as alternatives to their base system location. Thus 56# ldd(1) can be executed against these configuration files so that objects in a 57# proto area bind to their dependencies in the same proto area. 58 59 60# Define all global variables (required for strict) 61use vars qw($SkipDirs $SkipFiles $SkipTextrelFiles $SkipDirectBindFiles); 62use vars qw($SkipUndefFiles $SkipUnusedDeps); 63use vars qw($SkipStabFiles $SkipNoExStkFiles $SkipCrleConf); 64use vars qw($SkipUnusedSearchPath $SkipUnrefObject $SkipUnusedObject); 65use vars qw($Prog $Mach $Isalist $Env $Ena64 $Tmpdir $Error $Gnuc); 66use vars qw($UnusedPaths $LddNoU $Crle32 $Crle64 $Conf32 $Conf64); 67use vars qw($SkipDirectBindDirs $SkipInterps $SkipSymSort $OldDeps %opt); 68 69use strict; 70 71 72# Define any directories we should skip completely. 73$SkipDirs = qr{ 74 usr/lib/devfsadm | # 4382889 75 usr/lib/libc | # optimized libc 76 usr/lib/rcm | # 4426119 77 usr/perl5 | # alan's taking care of these :-) 78 usr/src # no need to look at shipped source 79}x; 80 81# Define any files we should skip completely. 82$SkipFiles = qr{ ^(?: 83 lddstub | # lddstub has no dependencies 84 geniconvtbl\.so | # 4384329 85 libssagent\.so\.1 | # 4328854 86 libpsvcplugin_psr\.so\.1 | # 4385799 87 libpsvcpolicy_psr\.so\.1 | # " " 88 libpsvcpolicy\.so\.1 | # " " 89 picl_slm\.so | # " " 90 mod_ipp\.so | # Apache loadable module 91 fptest | # USIII specific extns. cause ldd noise on USII bld. m/c 92 grub 93 )$ 94}x; 95 96# Define any files that are allowed text relocations. 97$SkipTextrelFiles = qr{ ^(?: 98 unix | # kernel models are non-pic 99 mdb # relocations against __RTC (dbx) 100 )$ 101}x; 102 103# Define any directories or files that are allowed to have no direct bound 104# symbols 105$SkipDirectBindDirs = qr{ 106 usr/ucb 107}x; 108 109$SkipDirectBindFiles = qr{ ^(?: 110 unix | 111 sbcp | 112 libproc.so.1 | 113 libnisdb.so.2 114 )$ 115}x; 116 117# Define any files that are allowed undefined references. 118 119$SkipUndefFiles = qr{ ^(?: 120 libsvm\.so\.1 | # libspmicommon.so.1 lacking 121 libnisdb\.so\.2 # C++ 122 )$ 123}x; 124 125# Define any files that have unused dependencies. 126$SkipUnusedDeps = qr{ 127 lib/picl/plugins/ | # require devtree dependencies 128 /lib/libp # profile libc makes libm an unused 129}x; # dependency of standard libc 130 131# Define any objects that always look unused. 132$SkipUnusedObject = qr{ 133 /libm_hwcap[0-9]+\.so\.2 # libm.so.2 dependency 134}x; 135 136# Define any files that should contain debugging information. 137$SkipStabFiles = qr{ ^(?: 138 unix 139 )$ 140}x; 141 142# Define any files that don't require a non-executable stack definition. 143$SkipNoExStkFiles = qr{ ^(?: 144 forth | 145 unix | 146 multiboot 147 )$ 148}x; 149 150# Identify any files that should be skipped when building a crle(1) 151# configuration file.
