Subject: [patch] Fix separate-debug with non-unique section names (PR 11409)

A different version was checked-in but they are interchangeable:

	http://sourceware.org/ml/gdb-patches/2010-03/msg00799.html

	http://sourceware.org/ml/gdb-cvs/2010-03/msg00241.html

Hi,

gdb-7.1 is now broken for example for debugging /usr/bin/emacs due to:

http://sourceware.org/bugzilla/show_bug.cgi?id=11409

  [22] .data   PROGBITS 00000000007fe8a0 1fe8a0 215068 00  WA  0   0 32

  [23] .data   PROGBITS 0000000000a13920 413920 68c6e0 00  WA  0   0 32

It is in fact a regression against gdb-7.0 by me due to:

commit 71d0069a9f238a11f7f455bf6ad2adfc25683521

Author: Jan Kratochvil <jan.kratochvil@redhat.com>

Date:   Tue Jan 5 15:51:01 2010 +0000

gdb/

        * symfile.c (syms_from_objfile): Remove the !MAINLINE conditional.

as while the code was broken even before the broken relocation was not applied

to mainline binary (before PIE+OSX patches went in).

No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.

OK to check-in also for gdb-7.1 (7.1.1)?

Thanks,

Jan
