a42e82976a Merge WARN and CWARN cases in _bfd_generic_link_add_one_symbol
WARN has always been able to be handled by the CWARN case (WARN was
used when the previous symbols was undef, undefweak or common and thus
must be on the undefs list, so the CWARN test passes).  So let's merge
those two cases.

	* linker.c (WARN, CWARN): Collapse these states to WARN.
	(_bfd_generic_link_add_one_symbol): Use old CWARN case for
	new WARN.

b6d7a4bf29 Rename variable with confusing name
I saw this gem of not so legible code in solib-svr4.c (scan_dyntag):

	if (dyn_tag == dyntag)

and thought it deserved a small rename.

This just renames variables to be a bit more clear for those who read the
code. I also constified the parameter because, why not. The same was
done in scan_dyntag_auxv as well.

Tested only by rebuilding, since the change was done mechanically.

13e570f80c Fix LTO vs. COFF archives
Avoid scan of symbols on objects in coff archives since we don't need
to do anything special with common symbols.  The scan is quite useless,
and breaks LTO due to slim LTO objects not having symbols available
until after the plugin has claimed them.  Instead we can add objects
based on their archive symbol map.

Also, rip out the archive symbol hash table used by the generic
linker.  Using a hash breaks one feature of unix archive linking;
The first object file in an archive defining any given symbol should
be the object extracted to satisfy that symbol.  What's more a hash
isn't much faster except in pathological cases where object file
ordering causes many scans of the archive.  See the comment which I'm
removing from elf_link_add_archive_symbols.

Finally, tidy elflink.c archive handling a little.

3cecbbbef1 make "set debug target" take effect immediately
Right now, "set debug target" acts a bit strangely.

Most target APIs only notice that it has changed when the target stack
is changed in some way.  This is because many methods implement the
setting using the special debug target.  However, a few spots do
change their behavior immediately -- any place explicitly checking
"targetdebug".

Some of this peculiar behavior is documented.  However, I think that
it just isn't very useful for it to work this way.  So, this patch
changes "set debug target" to take effect immediately in all cases.
This is done by simply calling update_current_target when the setting
is changed.

This required one small change in the test suite.  Here a test was
expecting the current behavior.

Built and regtested on x86-64 Fedora 20.

	* target.c (set_targetdebug): New function.
	(initialize_targets): Pass set_targetdebug when creating "set
	debug target".

2014-08-04  Tom Tromey  <tromey@redhat.com>

	* gdb.texinfo (Debugging Output): Update for change to "set debug
	target".

2014-08-04  Tom Tromey  <tromey@redhat.com>

	* gdb.base/sss-bp-on-user-bp-2.exp: Expect output from "set debug
	target 0".

00b51ff583 fix test suite regression
This fixes a test suite regession that Yao noticed.
This test checks for some specific "target debug" output
that has changed since the test was written.

2014-08-04  Tom Tromey  <tromey@redhat.com>

	* gdb.base/sss-bp-on-user-bp-2.exp: Match "to_resume", not
	"target_resume".

90debf20f4 [gdb/doc] Add target triplet to man files
After applying hash 43662968, gdb.1 and other man pages are not added
target triplet even if we configure with --target=.

It causes conflicts on some distributions.
And uninstall rules requires $(transform) variable.

gdb/doc/ChangeLog:

	* Makefile.in (transform): New variable.
	(install-man1, install-man5): Apply $(transform) to man file names.

Tested by installing both native and cross debugger.

6908c50982 Handle variable-sized fields in the interior of structure type
In Ada, variable-sized field can be located at any position of
a structure. Consider for instance the following declarations:

   Dyn_Size : Integer := 1;

   type Table is array (Positive range <>) of Integer;

   type Inner is record
      T1 : Table (1 .. Dyn_Size) := (others => 1);
      T2 : Table (1 .. Dyn_Size) := (others => 2);
   end record;

   type Inner_Array is array (1 .. 2) of Inner;

   type Outer is
      record
         I0 : Integer := 0;
         A1 : Inner_Array;
         Marker : Integer := 16#01020304#;
      end record;

   Rt : Outer;

What this does is declare a variable "Rt" of type Outer, which
contains 3 fields where the second (A1) is of type Inner_Array.
type Inner_Array is an array with 2 elements of type Inner.
Because type Inner contains two arrays whose upper bound depend
on a variable, the size of the array, and therefore the size of
type Inner is dynamic, thus making field A1 a dynamically-size
field.

When trying to print the value of Rt, we hit the following limitation:

    (gdb) print rt
    Attempt to resolve a variably-sized type which appears in the interior of
    a structure type

The limitation was somewhat making sense in C, but needs to be lifted
for Ada. This patch mostly lifts that limitation. As a result of this
patch, the type length computation had to be reworked a little bit.

gdb/ChangeLog:

        * gdbtypes.c (resolve_dynamic_struct): Do not generate an error
        if detecting a variable-sized field that is not the last field.
        Fix struct type length computation.

gdb/testsuite/ChangeLog:

        * gdb.base/vla-datatypes.c (vla_factory): Add new variable
        inner_vla_struct_object_size.
        * gdb.base/vla-datatypes.exp: Adjust last test, and mark it
        as xfail.

53e8f97d57 Add debug trace in amd64-windows-tdep.c::amd64_windows_frame_decode_insns
This is a trace which would have been useful when trying to understand
why the debugger was not decoding the stream of unwind codes I was
expecting.  This patch adds a trace first informing us that we are
following the unwind info to the next unwind record in that chain.

gdb/ChangeLog:

        * amd64-windows-tdep.c (amd64_windows_frame_decode_insns):
        Add debug trace.

e068c55d5e x64-windows: Fix extraction of chained UNWIND_INFO
On x86_64-windows, GDB is unable to unwind past some code in
mswsock.dll. For instance:

    (gdb) bt
    #0  0x00000000778712fa in ntdll!ZwWaitForSingleObject ()
       from C:\Windows\SYSTEM32\ntdll.dll
    #1  0x000007fefcfb0f75 in WSPStartup ()
       from C:\Windows\system32\mswsock.dll
    Backtrace stopped: previous frame inner to this frame (corrupt stack?)

The UNWIND_INFO record for frame #1's PC has a UNW_FLAG_CHAININFO
flag, and so after having decoded this unwind record, GDB's decoder
next tries to locate the next unwind record on the chain. Unfortunately,
the location of that unwind info appears to be miscomputed. This is
the expression used:

         chain_vma = cache->image_base + unwind_info
           + sizeof (ex_ui) + ((codes_count + 1) & ~1) * 2 + 8;

The chain-info is expected to be right after the "Unwind codes
array" which is itself after all the fields of ex_ui's struct.
So the "+ 8" offset at the end should not be there.

Because of that extra offset, we were reading no longer processing
correct unwind info, leading the unwinder computing the wrong frame
size, computing the wrong return address, etc.

gdb/ChangeLog:

        * amd64-windows-tdep.c (amd64_windows_frame_decode_insns):
        Remove "+ 8" offset in computation of CHAIN_VMA.
