Fix crash on optimized-out entry data values

that comparing a fully optimized out value's contents with a value
that has not been optimized out, or is partially optimized out crashes

... a fully optimized-out value can have it's value contents buffer

As a spotgap fix, revert 4f14910f, with a comment.  A full fix would
be too invasive for 7.8.

Remove setting value address for reference entry value target data value.

I cannot reproduce any wrong case having the code removed.

I just do not find it correct to have it disabled.  But at the same time I do
like much / I do not find correct the code myself.  It is a bit problematic to
have struct value describing a memory content which is no longer present
there.

At /* break-here */ struct value variable 'ref' is TYPE_CODE_REF.

With FSF GDB HEAD:
(gdb) x/gx arg1.contents
0x6004000a4ad0: 0x00007fffffffd944
(gdb) p ((struct value *)arg1.location.computed.closure).lval
$1 = lval_memory
(gdb) p/x ((struct value *)arg1.location.computed.closure).location.address
$3 = 0x7fffffffd944

With your #if0-ed code:
(gdb) x/gx arg1.contents
0x6004000a4ad0: 0x00007fffffffd944
(gdb) p ((struct value *)arg1.location.computed.closure).lval
$8 = not_lval
(gdb) p/x ((struct value *)arg1.location.computed.closure).location.address
$9 = 0x0

I do not see how to access
        ((struct value *)arg1.location.computed.closure).location.address
from GDB CLI.  Trying
(gdb) p &ref@entry
will invoke value_addr()'s:
  if (TYPE_CODE (type) == TYPE_CODE_REF)
      /* Copy the value, but change the type from (T&) to (T*).  We
         keep the same location information, which is efficient, and
         allows &(&X) to get the location containing the reference.  */
and therefore the address gets fetched already from
  arg1.contents
and not from
  ((struct value *)arg1.location.computed.closure).location.address
.

And for any other type than TYPE_CODE_REF this code you removed does not get
executed at all.  This DW_AT_GNU_call_site_data_value DWARF was meant
primarily for Fortran but with -O0 entry values do not get produced
and with -Og and higher Fortran always optimizes out the passing by reference.

If you do not like the removed code there I am OK with removing it as I do not
know how to make it's use reproducible for user anyway.  In the worst case
- if there really is some way how to exploit it - one should just get
  Attempt to take address of value not located in memory.
instead of some wrong value and it may be easy to fix then.

rewrite make-target-delegates matching code

This patch rewrites the make-target-delegates matching code a little
bit.  The result is functionally the same (the output has some small
whitespace differences), but the new code is more forgiving regarding
the formatting of target.h.  In particular now there's no need to
ensure that the return type and the method name appear on the same
line.

se typecast 'size_t' on 'reg', not only avoid the related warning, but
also check whether less than zero -- for 'reg' is type 'int', and sizeof
(dwarf2_to_reg_map) is less than 0x7fff.

It is quoted in gdb_assert(), so need check 'reg' whether less than zero.
And the related warning (with '-W'):

ChangeLog:

 * microblaze-tdep.c (microblaze_dwarf2_reg_to_regnum): Check whether

This patch uses target_read_code instead of target_read_memory in

requested in target_read_code.

Rationalize "fatal" error handling outside of gdbserver

GDB and gdbserver have functions named "fatal" that are used in
completely different ways.  In gdbserver "fatal" is used to handle
critical errors: it differs from "error" in that "fatal" causes
gdbserver to exit whereas "error" does not.  In GDB "fatal" is used
to abort the current operation and return to the command level.
This is implemented by throwing a non-error "RETURN_QUIT" exception.

This commit removes GDB's "fatal" and "vfatal" functions entirely.
The exception-throwing function "throw_vfatal" is renamed as
"throw_vquit", and a new convenience function "throw_quit" is added.
The small number of calls to "fatal" are replaced with calls to
"throw_quit", making what is happening more obvious.

This commit also modifies GDB's "throw_error" to call "throw_verror"
rather than calling "throw_it" directly.  This change means the
assignment of RETURN_ERROR as the exception type now happens in
precisely one place in GDB rather than two.

auto-generate most target debug methods

The target debug methods are inconsistently maintained.  Most to_*
methods have some kind of targetdebug awareness, but not all of them
do.  The ones that do vary in the quantity and quality of output they
generate.

This patch changes most of the target debug methods to be
automatically generated.  All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.

For example now you'd see:

    -> multi-thread->to_terminal_ours (...)
    -> multi-thread->to_is_async_p (...)
    <- multi-thread->to_is_async_p (0x1ebb580) = 1
    <- multi-thread->to_terminal_ours (0x1ebb580)
    -> multi-thread->to_thread_address_space (...)
    <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1

In this case you can see nested calls.  The "multi-thread" on the left
hand side is the topmost target's shortname.

There are some oddities with this patch.  I'm on the fence about it
all, I really just wrote it on a whim.

It's not simple to convert every possible method, since a few don't
participate in target delegation.

Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.

On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack.  The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier.  (That said there are some gotchas
lurking in this idea due to target stack introspection.)

Regtested on x86-64 Fedora 20.

Make gdbserver CORE_ADDR unsigned

Remove some GDBSERVER checks from linux-ptrace

This patch removes some GDBSERVER checks from nat/linux-ptrace.c.
Currently the code uses a compile-time check to decide whether some
flags should be used.  This changes the code to instead let users of
the module specify an additional set of flags; and then changes gdb's
linux-nat.c to call this function.  At some later date, when the back
ends are fully merged, we will be able to remove this function again.
