  "message": "gdb: make gdbarch_alloc take ownership of the tdep\n\nIt\u0027s currently not clear how the ownership of gdbarch_tdep objects\nworks.  In fact, nothing ever takes ownership of it.  This is mostly\nfine because we never free gdbarch objects, and thus we never free\ngdbarch_tdep objects.  There is an exception to that however: when\ninitialization fails, we do free the gdbarch object that is not going to\nbe used, and we free the tdep too.  Currently, i386 and s390 do it.\n\nTo make things clearer, change gdbarch_alloc so that it takes ownership\nof the tdep.  The tdep is thus automatically freed if the gdbarch is\nfreed.\n\nChange all gdbarch initialization functions to pass a new gdbarch_tdep\nobject to gdbarch_alloc and then retrieve a non-owning reference from\nthe gdbarch object.\n\nBefore this patch, the xtensa architecture had a single global instance\nof xtensa_gdbarch_tdep.  Since we need to pass a dynamically allocated\ngdbarch_tdep_base instance to gdbarch_alloc, remove this global\ninstance, and dynamically allocate one as needed, like we do for all\nother architectures.  Make the `rmap` array externally visible and\nrename it to the less collision-prone `xtensa_rmap` name.\n\nChange-Id: Id3d70493ef80ce4bdff701c57636f4c79ed8aea2\nApproved-By: Andrew Burgess \u003caburgess@redhat.com\u003e\n",
