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. gdbserver/ChangeLog: 2020-03-06 Tankut Baris Aktemur * linux-low.h (the_linux_target): New extern declaration. * linux-low.cc (initialize_low): Use 'the_linux_target' to set 'the_target'.
