The original code replicated the BFD + arch/mach switching done in rs6000_gdbarch_init; it's better to + keep that logic there, and just check the results here. + (rs6000_gdbarch_init): On the E500, set tdep->ppc_fp0_regnum and + tdep->ppc_fpscr_regnum to -1 to indicate that we have no + floating-point registers. + (ppc_supply_fpregset, ppc_collect_fpregset) + (rs6000_push_dummy_call, rs6000_extract_return_value) + (rs6000_store_return_value): Assert that we have floating-point + registers. + (rs6000_dwarf2_stab_reg_to_regnum): Add FIXME. + (rs6000_frame_cache): Don't note the locations at which + floating-point registers were saved if we have no fprs. + * aix-thread.c (supply_fprs, fill_fprs): Assert that we have FP + registers. + (fetch_regs_user_thread, fetch_regs_kernel_thread) + (store_regs_user_thread, store_regs_kernel_thread): Only call + supply_fprs / fill_fprs if we actually have floating-point + registers. + (special_register_p): Check ppc_fpscr_regnum before matching + against it. + (supply_sprs64, supply_sprs32, fill_sprs64, fill_sprs32): Don't + supply / collect fpscr if we don't have it. + * ppc-bdm.c: #include "gdb_assert.h". + (bdm_ppc_fetch_registers, bdm_ppc_store_registers): Assert that we + have floating-point registers, since I can't test this code on + FP-free systems to adapt it. + * ppc-linux-nat.c (ppc_register_u_addr): Don't match against the + fpscr and floating point register numbers if they don't exist. + (fetch_register): Assert that we have floating-point registers + before we reach the code that handles them. + (store_register): Same. And use tdep instead of calling + gdbarch_tdep again. + (fill_fpregset): Don't try to collect FP registers and fpscr if we + don't have them. + (ppc_linux_sigtramp_cache): Don't record the saved locations of + fprs and fpscr if we don't have them. + (ppc_linux_supply_fpregset): Don't supply fp regs and fpscr if we + don't have them. + * ppcnbsd-nat.c: #include "gdb_assert.h". + (getfpregs_supplies): Assert that we have floating-point registers. + * ppcnbsd-tdep.c (ppcnbsd_supply_fpreg, ppcnbsd_fill_fpreg): Same. + * ppcobsd-tdep.c: #include "gdb_assert.h". + (ppcobsd_supply_gregset, ppcobsd_collect_gregset): Assert that we + have floating-point registers. + * rs6000-nat.c (regmap): Don't match against the fpscr and + floating point register numbers if they don't exist. + (fetch_inferior_registers, store_inferior_registers, + fetch_core_registers): Only fetch / store / supply the + floating-point registers and the fpscr if we have them. + * Makefile.in (ppc-bdm.o, ppc-linux-nat.o, ppcnbsd-nat.o) + (ppcobsd-tdep.o): Update dependencies. + * rs6000-tdep.c (ppc_collect_gregset): When regnum == -1, do collect all the gprs. |
