            Bug ID: 59184
           Summary: Broken links
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: web
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pbl.ltx at gmail dot com

Greetings,

Here are a few broken links that I have spotted on the gcc web site.

Below is the url followed by the line number in source and the involved code
where the culprit is located:

1)
http://gcc.gnu.org/projects/beginner.html:64

    It may help to understand the higher-level <code>tree</code> structure as
    well.  Unfortunately, for this we only have an <a
    href="http://gcc.gnu.org/onlinedocs/gccint/Trees.html">incomplete, C/C++
specific manual</a>.</p>

Result: "Not found"

2)
http://gcc.gnu.org/projects/documentation.html:83

    <p>Fully document the interface of front ends to GCC, that is, the
    <code>tree</code>, <code>cgraph</code>, and <code>langhooks</code>
    interfaces, and the various functions, data structures, etc., that
    a front end must or may provide.</p>

    <p>We've got quite a bit of this but it is scattered all over the
    place.  It belongs in the official manual.  There is a <a
    href="http://gcc.gnu.org/onlinedocs/gccint/Trees.html">C/C++ specific
manual</a>,
    which is incomplete, though.

Result: Same as above. It's also pointing to the same document.

3)
http://gcc.gnu.org/readings.html:435

  <li><a
href="http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/">
      Objective-C Language Description</a> (Apple Computer)</li>

Result: Not valid, redirected. Does not point anymore to the relevant resource.

4)
http://gcc.gnu.org/wiki/WritingANewFrontEnd

Issue: The first entry on the list, which is "A GCC sample Frontend", returns
"Not found".

Godspeed.

1) and 2) should be perhaps: http://gcc.gnu.org/onlinedocs/gccint/GENERIC.html
3) should be perhaps:

--- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I would close it as WONTFIX but simply because I think this testcase is not
specially useful. First, this bug report is already covered by other reports
from PR24639 (several may apply in this case). Also, the optimizers may simply
remove "a" because it is not doing anything useful.

--- Comment #2 from Philippe Baril Lecavalier <pbl.ltx at gmail dot com> ---
(In reply to Manuel López-Ibáñez from comment #1)

Thanks for the suggestions, which I will apply. I have to admit that this is my
first time with cvs, so I'm taking notes here. I just want to check with you if
I got the correct workflow:

1. cvs checkout (anonymous, since no username)
2. go modify those three files
3. cvs diff -u projects/beginner.html projects/documentation.html readings.html
> broken_links_patch.diff 
4. cvs commit?

Questions:
a) Is there some preferable location where to write the patch? (in this case,
I've put it in "wwwdocs/htdocs")

b) Where do I write a brief description of what this is about, list modified
files and bug# in bugzilla?

c) Can I commit when I only have anonymous access? Do I have to set some
configuration file with my email in order to commit? (since it is sent to the
mailing list, I guess something would request an email). Or do I send the patch
to a mailing list?

Write to gcc-patches@gcc.gnu.org and attach the patch. Add [wwwdocs] to the
subject and CC gerald@pfeifer.com. Say that you don't have commit access. It
may take a few days for him to reply.
