  61
  62 <p>From the <a href="news:gnu.cvs.help">gnu.cvs.help</a> newsgroup I learned that doing a cvs log of everything then grepping through that is <b>much</b> faster than interrogating each file with cvs log. I then reorganized files4ecr to work in the following manner:</p>
  63
  64 <p>It occurred to me that often we wish to know, or pull, the file
  65 revision associated with an ECR #. I've created a script called
  66 files4ecr that accomplishes this:</p
  67
  68 <div class="code"><pre>
  69 <font color="#3333ff">saturn:</font><u>files4ecr-u</u>
  70 Usage: files4ecr [-v] [-d] [-l] [-x] [-u] &lt;ecr&gt;
  71
  72 Where:
  73
  74         -v:     Turn on verbose mode (Default: off)
  75         -d:     Turn on debug mode (Default: off)
  76         -l:     Local directory only, no recursion
  77         -x:     Turn on execute mode (Default: off)
  78         -u:     Dsplay usage
  79         ecr     ECR number to search for
  80 </pre>
  81 </div>
  82
  83 <p>The performance for this script is pretty good, depending on the amount of information in the CVS logs. Here's an example of it's usage:</p>
  84
  85 <div class="code"><pre>
  86 <font color="#3333ff"><b>saturn:</b></font><u>files4ecr 20505</u>
  87 SETUP.csh: 10.2 - Out of date
  88 etc/tconfig: 10.2 - Already up to date
  89 SETUP.bash: 10.6 - Out of date
  90 etc/ttys-arm: 1.1 - Already up to date
  91 Makefile: 10.13 - Out of date
  92 </pre></div>
  93
  94 <p>In noexecute mode it just displays the file and the revision of the
  95 file associated with that ECR. The -l option is similar to cvs' -l option:</p>
  96
  97 <div class="code"><pre>
  98 <font color="#3333ff">saturn:</font><u>files4ecr -l 20505</u>
  99 SETUP.csh: 10.2 - Out of date
 100 SETUP.bash: 10.6 - Out of date
 101 Makefile: 10.13 - Out of date
 102 </pre></div>
 103
 104 <p>Also, like cvs, files4ecr operates in the current context and current
 105 working directory.</p>
 106
 107 <p>With -x turned on files4ecr will perform the cvs update commands
 108 necessary to "pull" the versions for the ECR:</p>
 109
 110 <div class="code"><pre>
 111 <font color="#3333ff">saturn:</font><u>files4ecr -x 20505</u>
 112 cvs update -r10.2&nbsp; SETUP.csh - Updated
 113 cvs update -r10.2&nbsp; etc/tconfig - Already up to date
 114 cvs update -r10.6&nbsp; SETUP.bash - Updated
 115 cvs update -r1.1&nbsp; etc/ttys-arm - Already up to date
 116 cvs update -r10.13&nbsp; Makefile - Updated
 117 </pre></div>
 118
 119 <p>And we can see that the update has taken place:</p>
 120
 121 <div class="code"><pre>
 122 <font color="#3333ff">saturn:</font><u>files4ecr 20505</u>
 123 SETUP.csh: 10.2 - Already up to date
 124 etc/tconfig: 10.2 - Already up to date
 125 SETUP.bash: 10.6 - Already up to date
 126 etc/ttys-arm: 1.1 - Already up to date
 127 Makefile: 10.13 - Already up to date
 128 </pre></div>
 129
 130 <p>Anybody interested in such a script?</p>
 131
 132 <p><b>Note:</b> I've noticed that "ECR Number:" is not necessarily a
 133 consistent indicator of an ECR number. I search for several strings:</p>
 134
 135 <div class="code"><pre>
 136 /^ECR Number: (\d*)$/    or
 137 /^ECR# (\d*)$/           or
 138 /^ECR # (\d*)$/          or
 139 /^\s*ECR (\d*)/
 140 </pre></div>
 141
 142 <p>I've also noticed that a single ECR number may be attached to several revisions. files4ecr takes the latest revision in such cases.</p>
 143
 144 <h2>PPC toolchain build W/23084 is failing</h2>
 145
 146 <p>Preliminary investigation shows that while attempting to configure libiberty the build process is unable to use gcc to compile things. It seems to be lacking a crt1.o</p>
