PowerPC64 ELFv1 function symbol definition vs LTO and discarded sections
When functions are emitted in comdat groups, global symbols defined in
duplicates of the group are treated as if they were undefined. That
prevents the symbols in the discarded sections from affecting the
linker's global symbol hash table or causing duplicate symbol errors.
Annoyingly, when gcc emits a function to a comdat group, it does not
put *all* of a function's code and data in the comdat group.
Typically, constant tables, exception handling info, and debug info
are emitted to normal sections outside of the group, which is a
perennial source of linker problems due to the special handling needed
to deal with the extra-group pieces that ought to be discarded. In
the case of powerpc64-gcc, the OPD entry for a function is not put in
the group. Since the function symbol is defined on the OPD entry this
means we need to handle symbols in .opd specially.
To see how this affects LTO in particular, consider the linker
testcase PR ld/12942 (1). This testcase links an LTO object file
pr12942a.o with a normal (non-LTO) object pr12942b.o. Both objects
contain a definition for _Z4testv in a comdat group. On loading
pr12942a.o, the linker sees a comdat group (actually linkonce section)
for _Z4testv and a weak _Z4testv defined in the IR. On loading
pr12942b.o, the linker sees the same comdat group, and thus discards
it. However, _Z4testv is a weak symbol defined in .opd, not part of
the group, so this weak symbol overrides the weak IR symbol. On
(re)loading the LTO version of pr12942a.o, the linker sees another
weak _Z4testv, but this one does not override the value we have from
pr12942b.o. The result is a linker complaint about "`_Z4testv'
... defined in discarded section `.group' of tmpdir/pr12942b.o".
* elf64-ppc.c (ppc64_elf_add_symbol_hook): If function code
section for function symbols defined in .opd is discarded, let
the symbol appear to be undefined.
(opd_entry_value): Ensure the result section is that for the

Use gdb_test_sequence in gdb.base/save-bp.exp.
But IMO it is a functionality regression as:
* gdb_test_sequence permits arbitary number of lines of text between those

This may make a difference if GDB regresses by printing some unexpected
line after the breakpoint info line (like a "silent" line).

by Yao Qi:
In this test case, ( \\((host|target) evals\\))? isn't needed in the
pattern. What we test here is to save breakpoints into file and restore
them from file. The contents saved in file are:
break save-bp.c:31
condition $bpnum i == 1
the information about the place where the condition is evaluated isn't
saved, so we don't need to check. Breakpoint save and restore has
nothing to do with where the condition is evaluated (host or target). I
am fine to leave it here now.

The test tries to kill gdbserver in this way:

Cache the vsyscall/vDSO range per-inferior
We're now doing a vsyscall/vDSO address range lookup whenever we fetch
shared libraries, either through an explicit "info shared", or when
the target reports new libraries have been loaded, in order to filter
out the vDSO from glibc's DSO list. Before we started doing that, GDB
would only ever lookup the vsyscall's address range once in the
process's lifetime.
Looking up the vDSO address range requires an auxv lookup (which is
already cached, so no problem), but also reading the process's
mappings from /proc to find out the vDSO's mapping's size. That
generates extra RSP traffic when remote debugging. Particularly
annoying when the process's mappings grow linearly as more libraries
are mapped in, and we went through the trouble of making incremental
DSO list updates work against gdbserver (when the probes-based dynamic
linker interface is available).
The vsyscall/vDSO is mapped by the kernel when the process is
initially mapped in, and doesn't change throughout the process's
lifetime, so we can cache its address range.
Caching at this level brings GDB back to one and only one vsyscall
address range lookup per process.
Tested on x86_64 Fedora 20.

PR symtab/14466: Work around PR libc/13097 "linux-vdso.so.1"
With upstream glibc, GDB prints:
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
A bug's been filed for glibc a few years back:
http://sourceware.org/bugzilla/show_bug.cgi?id=13097
but it's still not resolved. It's not clear whether there's even
consensus that this is indeed a glibc bug. It would actually be nice
if GDB also listed the vDSO in the shared library list, but there are
some design considerations with that:
- the vDSO is mapped by the kernel, not userspace, therefore we
should load its symbols right from the process's start of life,
even before glibc / the userspace loader sets up the initial DSO
list. The program might even be using a custom loader or no
loader.
- that kind of hints at that solib.c should handle retrieving shared
library lists from more than one source, and that symfile-mem.c's
loading of the vDSO would be converted to load and relocate the
vDSO's bfd behind the target_so_ops interface.
- and then, once glibc links in the vDSO to its DSO list, we'd need
to either:
a) somehow hand over the vDSO from one target_so_ops to the other
b) simply keep hiding glibc's entry.
And then b) seems the simplest.
With that in mind, this patch simply discards the vDSO from glibc's
reported shared library list.
We can match the vDSO address range with the addresses found iterating
the dynamic linker list, to tell which dynamic linker entry is the
vDSO.

Split vDSO range lookup to a gdbarch hook
We have a case in solib-svr4.c where we could reuse symfile-mem.c's
vDSO range lookup. Since symfile-mem.c is not present in all
configurations solib-svr4.c is, move that lookup to a gdbarch hook.
This has the minor (good) side effect that we stop even trying the
target_auxv_search lookup against targets that don't have a concept of
a vDSO, in case symfile-mem.c happens to be linked in the build
(--enable-targets=all).

PR tdep/9390: Fix typo on xstorxstormy16-tdep.c
This patch fixes the bug described in PR tdep/9390, which is about a
wrong check in the following code:
...
/* optional copying of args in r2-r7 to r10-r13. */
/* Probably only in optimized case but legal action for prologue. */
else if ((inst & 0xff00) == 0x4600 /* 46SD mov rD, rS */

This condition will never trigger, and the fix proposed in the bug
(which made sense to me) was to test against 0x000a. I tried finding
documentation about this target, but couldn't find anything. I don't
even know if it is still used, but decided to submit the fix anyway.
