The first part has caused the regression for PIE on native x86* GNU/Linux host.
|
||||||
|
|
||||||
|
As I believe for Daniel J.'s seen regression of `qOffsets' the second already
|
||||||
|
checked-in part is sufficient - I would like to remove the first part.
|
||||||
|
|
||||||
|
OK to check it in?
|
||||||
|
|
||||||
|
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
|
||||||
|
|
||||||
|
(I do not think one needs to think about 7.1-branch as it is not a regression
|
||||||
|
against any FSF GDB release.)

Subject: [patch] Fix separate-debug with non-unique section names (PR 11409)
|
||||||
|
|
||||||
|
A different version was checked-in but they are interchangeable:

||||||

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
|
||||||

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,
|
