Add REGCACHE parameter. Use it instead of current_regcache. (i386nto_supply_regset): Add REGCACHE parameter, pass it to i386nto_supply_gregset and i386nto_supply_fpregset. (i386nto_regset_fill): Add REGCACHE parameter; use it instead of current_regcache. * nto-procfs.c (procfs_fetch_registers): Pass current_regcache to nto_supply_ helper functions. (procfs_store_registers): Pass current_regcache to nto_regset_fill. * nto-tdep.c (nto_dummy_supply_regset): Add REGCACHE parameter. * nto-tdep.h (struct nto_target_ops): Add REGCACHE parameter to supply_greget, supply_fpregset, supply_altregset, supply_regset, and regset_fill member function pointers. (nto_dummy_supply_regset): Adapt prototype.
