ef0478f611 gdbserver/linux-low: start turning linux target ops into methods 
This is the beginning of a series of patches that convert the linux
low targets into classes derived from linux_process_target.  At the
end of the series we obtain a class hierarchy that looks like this:

process_stratum_target
^
|
|-- linux_process_target
    ^
    |
    |-- x86_target (defined in linux-x86-low)
    |-- aarch64_target (defined in linux-aarch64-low)
    |-- ppc_target (defined in linux-ppc-low)
    |-- ...

In several cases, linux_process_target simply forwards a target op
request to a corresponding linux_target_ops function.  For these
cases, the definition in linux_process_target will be removed and the
definition will be left to the deriving linux low target class; using
inheritance provides a nice and natural, object-oriented
simplification in these cases.

The series converts linux_target_ops into protected methods of
linux_process_target one by one.  Throughout the series, based on the
needs, static functions defined in linux-low.cc are converted to
private methods of linux_process_target as well.  This is done either
as separate patches or as integrated into a patch that convert a
particular linux_target_op into a method.

The series ends with the patch titled "gdbserver/linux-low: delete
'linux_target_ops' and 'the_low_target'".

Built and regression-tested on x86_64-linux.  The following linux low
targets have been built (but not tested) via cross-compilation:
aarch64, arm, m68k, mips, ppc, riscv, s390, sh, sparc.  The other
targets (bfin, cris, crisv32, ia64, m32r, nios2, tic6x, tile, xtensa)
were neither built nor tested.

a5863204fb gdbserver: make linux target op 'cannot_store_register' a predicate function 
The comment for the linux target op 'cannot_store_register' states the
following:

  /* Returns 0 if we can store the register, 1 if we can not
     store the register, and 2 if failure to store the register
     is acceptable.  */

There is only one low target, linux-ppc-low, that potentially returns
2.  There are two places that call the 'cannot_store_register' target
op in linux-low.cc.  None of these locations distinguish a '2' from a
'1'.  Hence, to simplify the definition, make the function a predicate
that returns either 0 or 1.  This is also consistent with the
companion function, 'cannot_fetch_register'.

gdbserver/ChangeLog:
2020-04-02  Tankut Baris Aktemur  <tankut.baris.aktemur@intel.com>

	* linux-low.h (struct linux_target_ops): Update the comment for
	'cannot_store_register' to return 0 or 1.
	* linux-ppc-low.cc (ppc_cannot_store_register): Return 1 instead
	of 2.

52405d85ec gdbserver: finish turning the target ops vector into a class 
Now that 'process_stratum_target' has a single field left, namely 'pt'
of type 'process_target', and that all the requests to a
'process_stratum_target' are forwarded to 'pt', meld the
'process_target' class into 'process_stratum_target'.

This essentially means

1. All the references of the form 'the_target->pt' become 'the_target'.

2. All the uses of the name 'process_target' become
   'process_stratum_target'.

3. The platform-specific target op vectors (e.g. linux_target_ops) are
   removed and instances of their "process target" classes are used
   instead.
