ca55926c2f Omit section dynsyms for any linker created section
This is a simplification, and fixes a testcase I had where an empty
powerpc64 .branch_lt section was chosen for the data_index_section
dynamic symbol and thus wasn't removed.

	* elflink.c (_bfd_elf_link_omit_section_dynsym): Return true for
	any output section matching a linker created dynobj section.

8539e4e89e Fix ARM fail of gap test
ld-elf/gap test was failing due to the ARM backend attempting to output
arch symbols when ld -s (strip all symbols) is in force.  This patch
stops that happening and tidies the code a little.

	PR 17842
	* elflink.c (elf_link_output_sym): Assert elf_onesymtab set.
	(bfd_elf_final_link): Always create a symbol table when emit_relocs.
	Don't assign symtab file position unless symbols will be output.
	Merge blocks with condition in common.  Don't call
	elf_backend_output_arch_local_syms or elf_backend_output_arch_syms
	unless other symbols are output.  Move assignment of symtab_shndx
	file position.  Localize variable.

bafffb51c4 [Ada] 'first/'last/'length of array whose bound is a discriminant
Consider the following code:

   type Table is array (Positive range <>) of Integer;
   type Object (N : Integer) is record
       Data : Table (1 .. N);
   end record;
   My_Object : Object := (N => 3, Data => (3, 5, 8));

Trying to print the range and length of the My_Object.Data array yields:

    (gdb) print my_object.data'first
    $1 = 1
    (gdb) print my_object.data'last
    $2 = 0
    (gdb) print my_object.data'length
    $3 = 0

The first one is correct, and that is thanks to the fact that
the lower bound is statically known.  However, for the upper
bound, and consequently the array's length, the values are incorrect.
It should be:

    (gdb) print my_object.data'last
    $2 = 3
    (gdb) print my_object.data'length
    $3 = 3

What happens here is that ada_array_bound_from_type sees that
our array has a parallel "___XA" type, and therefore tries to
use it.  In particular, it described our array's index type as:
[...]___XDLU_1__n, which means lower bound = 1, and upper bound
is value of "n". Unfortunately, ada_array_bound_from_type does
not have access to the discriminant, and is therefore unable to
compute the bound correctly.

Fortunately, at this stage, the bound has already been computed
a while ago, and therefore doesn't need to be re-computed here.
This patch fixes the issue by ignoring that ___XA type if the array
is marked as already fixed.

This also fixes the same issue with packed arrays.

gdb/ChangeLog:

        * ada-lang.c (ada_array_bound_from_type): Ignore array's parallel
        ___XA type if the array has already been fixed.

cdf436294f Detect 64-bit-ness in PowerPC Book III-E
This patch is to teach both GDB and GDBServer to detect 64-bit inferior
correctly.  We find a problem that GDBServer is unable to detect on a
e5500 core processor.  Current GDBServer assumes that MSR is a 64-bit
register, but MSR is a 32-bit register in Book III-E.  This patch is
to fix this problem by checking the right bit in MSR, in order to handle
both Book III-S and Book III-E.  In order to detect Book III-S and
Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by
getauxval on glibc >= 2.16.  If getauxval doesn't exist, we implement
the fallback by parsing /proc/self/auxv), because it should an invariant
on the same machine cross different processes.

In order to share code, I add nat/ppc-linux.c for both GDB and
GDBserver side.

5589af0e66 PR17525 - breakpoint commands not executed when program run from -x script
Executing a gdb script that runs the inferior (from the command line
with -x), and has it hit breakpoints with breakpoint commands that
themselves run the target, is currently broken on async targets
(Linux, remote).

While we're executing a command list or a script, we force the
interpreter to be sync, which results in some functions nesting an
event loop and waiting for the target to stop, instead of returning
immediately and having the top level event loop handle the stop.

The issue with this bug is simply that bpstat_do_actions misses
checking whether the interpreter is sync.  When we get here, in the
case of executing a script (or, when the interpreter is sync), the
program has already advanced to the next breakpoint, through
maybe_wait_sync_command_done.  We need to process its breakpoints
immediately, just like with a sync target.

Tested on x86_64 Fedora 20.

6c400b59d5 PR cli/17828: -batch -ex r breaks terminal
Commit d3d4baed (PR python/17372 - Python hangs when displaying
help()) had the side effect of causing 'gdb -batch' to leave the
terminal in the wrong state if the program was run.  E.g,.

 $ echo 'main(){*(int*)0=0;}' | gcc -x c -; ./gdb/gdb -batch -ex r ./a.out
 Program received signal SIGSEGV, Segmentation fault.
 0x00000000004004ff in main ()
 $

If you start typing the next command, seemingly nothing happens - GDB
left the terminal with echo disabled.

The issue is that that "r" ends up in fetch_inferior_event, which
calls reinstall_readline_callback_handler_cleanup, which causes
readline to prep the terminal (raw, echo disabled).  But "-batch"
causes GDB to exit before the top level event loop is first started,
and then nothing de-preps the terminal.

The reinstall_readline_callback_handler_cleanup function's intro
comment mentions:

 "Need to do this as we go back to the event loop, ready to process
 further input."

but the implementation forgets the case of when the interpreter is
sync, which indicates we won't return to the event loop yet, or as in
the case of -batch, we have not started it yet.

The fix is to not install the readline callback in that case.

For the test, in this case, checking that command echo still works is
sufficient.  Comparing stty output before/after running GDB is even
better.  Because stty may not be available, the test tries both ways.
In any case, since expect's spawn (what we use to start gdb) creates a
new pseudo tty, another expect spawn or tcl exec after GDB exits would
not see the wrong terminal settings.  So instead, the test spawns a
shell and runs stty and GDB in it.

Tested on x86_64 Fedora 20.

576fd14c68 gdb/testsuite: Make clean mostlyclean should not delete *.py.
A sanity-check in my release scripts caught something: After having
created the tarballs, I verify that no checked-in file disappeared
in the process, and lo and behod, it found that the following file
got wiped:

    - gdb/testsuite/dg-extract-results.py:

And it's not part of the tarball either.

I don't understand while we delete all *.py files in gdb/testsuite,
since I don't see a rule that expected to create one. A run of the
testsuite also doesn't seem to be creating .py files there.
I traced this to the following commit, which unfortunately provided
no explanation. Perhaps we used to run some tests in the gdb/testsuite
directory and caused files to be left behind there. Perhaps we still
do today?

In the meantime, Executive Decision: In order to allow me to create
tarballs without losing files, I removed it. It's easy to put something
back if we find out why it might still be needed.

gdb/testsuite/ChangeLog:

        * Makefile.in (clean mostlyclean): Do not delete *.py.

Tested on x86_64-linux by running the src-release.sh script again,
and this time, dg-extract-results.py no longer gets wiped.

04dccad086 [python/Ada] gdb.lookup_type fails to looking primitive type
The following change...

    commit 1994afbf19
    Date:   Tue Dec 23 07:55:39 2014 -0800
    Subject: Look up primitive types as symbols.

... caused the following regression:

    % gdb
    (gdb) set lang ada
    (gdb) python print gdb.lookup_type('character')
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    gdb.error: No type named character.
    Error while executing Python code.

This is because the language_lookup_primitive_type_as_symbol call
was moved to the la_lookup_symbol_nonlocal hook. A couple of
implementations have been upated accordingly, but the Ada version
has not. This patch fixes this omission.

08b13bdd82 Append to input history file instead of overwriting it
This patch makes readline append new history lines to the GDB history
file on exit instead of overwriting the entire history file on exit.
This change allows us to run multiple simultaneous GDB sessions without
having each session overwrite the added history of each other session on
exit.

Care must be taken to ensure that the history file doesn't get corrupted
when multiple GDB processes are trying to simultaneously append to and
then truncate it.  Safety is achieved in such a situation by using an
intermediate local history file to mutually exclude multiple processes
from simultaneously performing write operations on the global history
file.

696025802e gas: allow labeling of CFI instructions
When runtime patching code (like e.g. done by the Linux kernel) there
may be cases where the set of stack frame alterations differs between
unpatched and patched code. Consequently the corresponding unwind data
needs patching too. Locating the right places within an FDE, however,
is rather cumbersome without a way to insert labels in the resulting
section. Hence this patch introduces a new directive, .cfi_label. Note
that with the way CFI data gets emitted currently (at the end of the
assembly process) this can't support local FB- and dollar-labels.

6a3ca06752 Temporarily revert symbol lookup cache.
clear_symtab_users calls breakpoint_re_set before
observer_notify_new_objfile(NULL), and thus symbol lookup
done during breakpoint_re_set will see a stale cache.

Presumably we just need to move the call to observer_notify_new_objfile(NULL)
to before breakpoint_re_set, but need to check for other such issues,
and 7.9 is scheduled to branch tomorrow.
