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.
