I would like to be able to use non-trivial types in gdbarch_tdep types. This is not possible at the moment (in theory), because of the one definition rule. To allow it, rename all gdbarch_tdep types to <arch>_gdbarch_tdep, and make them inherit from a gdbarch_tdep base class. The inheritance is necessary to be able to pass pointers to all these <arch>_gdbarch_tdep objects to gdbarch_alloc, which takes a pointer to gdbarch_tdep. These objects are never deleted through a base class pointer, so I didn't include a virtual destructor. In the future, if gdbarch objects deletable, I could imagine that the gdbarch_tdep objects could become owned by the gdbarch objects, and then it would become useful to have a virtual destructor (so that the gdbarch object can delete the owned gdbarch_tdep object). But that's not necessary right now. It turns out that RISC-V already has a gdbarch_tdep that is non-default-constructible, so that provides a good motivation for this change. Most changes are fairly straightforward, mostly needing to add some casts all over the place. There is however the xtensa architecture, doing its own little weird thing to define its gdbarch_tdep. I did my best to adapt it, but I can't test those changes. Change-Id: Ic001903f91ddd106bd6ca09a79dabe8df2d69f3b
