libiberty configuration for DJGPP

libiberty configuration for DJGPP

[Eli Zaretskii]

The current libiberty misconfigures itself for native DJGPP builds,
because it tries to avoid compiling and linking test programs, for
cross-compilation's sake.  But the necessary bits that tell the
configure script what functions are available in the DJGPP library are
in the wrong place: the one that is run during the native build as
well, and there's no reason to avoid linking in that case.  The result
is that the native DJGPP build of GDB is unnecessarily broken, because
GDB needs several functions from libiberty that are unavailable in the
DJGPP library, but are not auto-detected.

The suggested patch below fixes that by moving the explicit list of
known functions to a place that only gets run when cross-compiling.
While at that, I also added to that part the functions needed by GDB
which need to be provided by libiberty.  The native build will now
auto-detect all the required functions.

This is OK.

Thanks.

In the future, please send patches only to gcc-patches@, not to both
gcc-patches@ and gcc@.  Thanks.

Is sources.redhat.com:/cvs/src the master repository for this file?
If not, I'm not sure I have write access to commit these changes.

Will do, and sorry for the extra noise.

Thanks.

No, the master repository is the gcc.gnu.org Subversion repository.
Anybody want to volunteer to commit this patch?

(By the way, sources.redhat.com is the old name.  sourceware.org is
preferred.)

[RFC] change sources.redhat.com to sourceware.org in gdbadmin/ss dir (was: libiberty configuration for DJGPP)

  Shouldn't we update 
the files in ss directory, then?

I am not really sure about insight reference in README,
as this is still seems to be more a redhat
than a GNU project.

That's a good suggestion. For insight, you could check on the insight
mailing list. I'm pretty confident they'll be OK with the change.

As Keith also gave his approval for the insight part,
I committed the change to the ss directory.

OK, I switched my scripts to use that one instead.

[RFC] change sources.redhat.com to sourceware.org in gdbadmin/ss dir (was: libiberty configuration for DJGPP)

[Pierre Muller]

I proposed this patch for gdbadmin/ss directory

Ian tought it was a good idea, and added that I should ask 
directly on insight mailing list about this issue I raised:

I am not really sure about insight reference in README,
as this is still seems to be more a redhat
than a GNU project.

  Should we leave sources.redhat.com for all insight 
related references or also switch to sourceware.org?

The name of the site really is sourceware.org but insight isn't really
officially supported by Red Hat anymore (and hasn't been for years) so I
don't see any reason to keep the .redhat.com for insight's sake.

If we were talking about something like systemtap or frysk then that
would be a different story...
