Subject: [patch 4/4]#3 Remove redundant lp->siginfo
Hi,
this is a simplification which should not affect GDB behavior. As linux-nat
now stops on each received signal without any reordering of them then
PTRACE_GETSIGINFO is enough to access siginfo, without any need to copy it in
advance.
Thanks,
Jan

Subject: [RFA] Fix inconsistency in blockvector addrmap vs non-addrmap handling
Hi.
I was seeing the assert in dw2_find_pc_sect_psymtab trigger
and traced it to the fact that when pending_addrmap_interesting gets
set blockvector.map is used instead of blockvector.block.
The difference is that blockvector.block contains entries for the global
and static blocks whereas pending_addrmap doesn't.
This patch fixes this by making them consistent.
I suspect more work is necessary (e.g. can symtabs "overlap" even though
the individual pieces do not?).
But I first want to fix the regression introduced by the change
to dw2_find_pc_sect_psymtab: There is more code in a symtab than is
documented by function and lexical block pc ranges (e.g. C++ method thunks).
Regression tested on amd64-linux, and by verifying the assert no longer
triggers in the testcase I was using.
Ok to commit?
Note that this obviates the need for the patch in:
http://sourceware.org/ml/gdb-patches/2012-05/msg00958.html
Also note that this accompanies this patch:

Subject: [patch] Fix another stale frame_info * (PR 11914, like PR 13866)
Hi,
http://sourceware.org/bugzilla/show_bug.cgi?id=11914
has another case of stale frame_info *. Originally I found it unfixable with
the current struct frame_info * usage but Pedro has shown in PR 13866 it is
possible to fix the cases one by one so I have fixed also this one.
It follows the path of valgrind backtrace showing where the memory is being
freed:
http://sourceware.org/bugzilla/show_bug.cgi?id=11914#c5
This message has been already present in GDB so I used it in more cases:
+ warning (_("Unable to restore previously selected frame."));
No regressions on {x86_64,x86_64-m32,i686}-fedorarawhide-linux-gnu.
I will check it in soon for 7.5.
I find it a bit difficult to reliably reproduce, this testcases mostly always
crashes for me (at least with -lmcheck).
Thanks,
Jan

Subject: [obv] testsuite: Fix fission-reread.S regression by me
Hi Doug,
I broke the testcase by patch
[patch 1/2] testcase: Make it -m32 compatible [Re: [commit] Fix rereading of DWO DIEs]
http://sourceware.org/ml/gdb-patches/2012-07/msg00009.html
The testcase itself usually PASSes but sometimes it does not. It is more
clear with 'readelf -wi':
<7b> DW_AT_frame_base : 97 byte block: 7a 0 1 7 19 8b 7e ac ce f1 22 90 2 fb 1 0 0 0 0 0 0 0 0 0 0 0 0 0 51 cd 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (DW_OP_breg10 (r10): 0; (Unknown location op))
Checked in.
Sorry,
Jan
