Hi,
just some reformatting to make the later patch more clear. There should be no
functionality difference by this patch. c1+c2 are a bit ugly but I found any
other solution a bit ugly.
Thanks,

New variables c1 and c2.

Subject: [patch 2/3] case insensitive: re_comp->regcomp
Hi,
re_comp cannot be passed REG_ICASE. Therefore change the code. The should
have no functionality impact.
The new boolean field `preg_p' could be maybe replaced by a conditional
`preg.buffer != NULL' which would work with libiberty regcomp implementation
but I do not see it guaranteed anywhere. GDB is always using static libiberty
implementation which I do not see why in the case it is running on glibc.
But if it gets fixed one day and it starts to use externally linked
regcomp/regexec I would find the `preg.buffer != NULL' conditional dangerous.
Thanks,
Jan

Replace re_comp/re_exec by regcomp/regexec.
* symtab.c (struct search_symbols_data): New fields preg, preg_p.
(search_symbols_name_matches): Use them, use regexec.
(search_symbols): New variable retval_chain, adjust the use of
old_chain against it. Replace re_comp by regcomp. Use the new struct
search_symbols_data fields, use regexec instead of re_exec.

Subject: [patch] testsuite: Test readline-6.2 "ask" regression
Hi,
this problem does not affect default FSF GDB build as it is using bundled
readline-5.1. But with system readline-6.2 and build using:
--with-system-readline use installed readline library
GDB will no longer ask about displaying too many symbols and dumps them all
immediately.
PASS:
$ gdb gdb
(gdb) p <tab><tab>
Display all 21482 possibilities? (y or n)_
FAIL:
$ gdb gdb
(gdb) p <tab><tab>
Display all 22129 possibilities? (y or n)
../../bfd/aout-target.h cs_to_section
../../bfd/aout32.c ctime
<screens and screens of dumps without any question>
This regression will soon start affecting distros:
FSF GDB HEAD - PASS - using bundled readline-5.1
fedora-15 - FAIL - using system readline-6.2
fedora-14 - PASS - using system readline-6.1
debian-6.0 - PASS - using system readline-6.1
kubuntu-10.10 - PASS - using system readline-6.1
I have asked about it on readline ml:
Re: [Bug-readline] callback mode pager disable status
https://lists.gnu.org/archive/html/bug-readline/2011-04/msg00012.html
The suggested workaround (in fact the readline-5.1 code state) going to patch
into the proposed FSF GDB bundled readline-6.2. Distros then can stop using
--with-system-readline to still feature recent and system matching readline
until readline-7.0 gets released.
This regression has been so far caught only with system debug infos installed:
-PASS: gdb.base/completion.exp: complete (2) 'p no_var_named_this-'
-PASS: gdb.base/completion.exp: complete 'p values[0].a'
-PASS: gdb.base/completion.exp: complete 'p values[0] . a'
-PASS: gdb.base/completion.exp: complete 'p &values[0] -> a'
-PASS: gdb.base/completion.exp: copmletion of field in anonymous union
+FAIL: gdb.base/completion.exp: (timeout) complete (2) 'p no_var_named_this-'
+FAIL: gdb.base/completion.exp: (timeout) complete 'p values[0].a' 2
+FAIL: gdb.base/completion.exp: (timeout) complete 'p values[0] . a' 2
+FAIL: gdb.base/completion.exp: (timeout) complete 'p &values[0] -> a' 2
+FAIL: gdb.base/completion.exp: copmletion of field in anonymous union
I will check it in with no comments.

Subject: [patch 3/3] Display core reasons even during thread error

Hi,
this is mostly unrelated. But after the patch 2/3 it will still FAIL:
Loaded symbols for /lib64/ld-linux-x86-64.so.2
Cannot find new threads: debugger service failed
(gdb) FAIL: gdb.threads/gcore-thread.exp: re-load generated corefile
as it is a common bug I dislike for years I have fixed it here:
Loaded symbols for /lib64/ld-linux-x86-64.so.2
Cannot find new threads: debugger service failed
Core was generated by `.../gdb/testsuite/gdb.threads/gcore-thread'.
Program terminated with signal 5, Trace/breakpoint trap.
#0 thread2 (arg=0xdeadbeef) at ./gdb.threads/pthreads.c:91
91 int k = 0;
(gdb) PASS: gdb.threads/gcore-thread.exp: re-load generated corefile
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.

Subject: [patch] workaround gcc46: prologue skip skips too far (PR 12435) #2
Hi,
this is an improved patch of a former:
[patch] workaround gcc46: prologue skip skips too far (PR 12435)
http://sourceware.org/ml/gdb-patches/2011-03/msg01108.html
cancel/FYI: Re: [patch] workaround gcc46: prologue skip skips too far (PR 12435)
http://sourceware.org/ml/gdb-patches/2011-03/msg01123.html
For example `break error' does not work for debugging GDB with gcc-4.6.x.
As gcc-4.6.0 and now even 4.6.1 still has this bug and I have seen a user(s?)
on non-Fedora platform asking about this bug and as there may be enough
binaries out there (although it affects only -O0 -g compilation) coded it
properly I have coded the workaround properly this time.
It does not solve overlays well, but the code just does not work for overlays,
it has no other negative effect.
I will update the code after FSF gcc gets fixed to minimize the workaround.
No regressions on {x86_64,x86_64-m32,i686}-fedora16pre-linux-gnu.
I would welcome a comment whether it is suitable for FSF GDB.
Thanks,
Jan

Subject: [patch] Workaround buggy GCC PR 47510 produced code
Hi,
GCC PR debug/47510 is already fixed and GDB has the proper support for it:
RFC: update for GCC PR 47510
http://sourceware.org/ml/gdb-patches/2011-03/msg00916.html
Still FSF GDB HEAD will crash on a binary produced by older/buggy GCC:
Reading symbols from .../gcc46.o...dwarf2read.c:9329: internal-error: could not find partial DIE 0x9a in cache [from module .../gcc46.o]
Which may not give much clue to the user.
The proposed patch could make false warnings if any code out there has
DW_TAG_typedef with children, it does not check for specific GCC versions.
Still such DWARF is invalid, although in such case complaint() would be more
appropriate than warning(). Does it make sense to differentiate it?
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
Thanks,
Jan

So far GDB expected all such displacements will be always PAGE_SIZE aligned.
This applies for example for re-prelinking of an already prelinked file.
But it does not apply for prelinking of an unprelinked file or unprelinking of
a prelinked file, there can be arbitrary displacement.
It affects i386 (=i686, prelink doc reports also ARM and MIPS) which uses REL.
x86_64 always uses RELA, therefore I have not noticed it so far. i386 still
has to be supported.
This affects both attachment to a PID and core file loads.
This applies in real world if you transfer a core file between hosts and try to
backtrace them, libraries of both hosts may differ whether they are / are not
prelinked.
I could implement some (displacement-forgiving and prelink-modifications
forgiving) comparison of both DYNAMIC segments found. But I do not think it is
useful, if the DYNAMIC address from linkmap vs. bfd do not match it is still a
better chance to try a displacement to make them match. Keeping the file
relocation cannot work anyway when the DYNAMIC address is verified as wrong.
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
Mostly do you agree the DYNAMIC content does not have to be verifed?
Do you have any comments on the in-code long comments?
Thanks,
Jan

Fix libraries displacement if they change whether they were prelinked.
* solib-svr4.c (LM_ADDR_CHECK): Set L_ADDR even if the DYNAMIC pointer
does not match. Comment why.

I would check it in as obvious but the 2011 ChangeLog move process has to be
done first. So to be checked in later.
Thanks,
