register */
* ppc-tdep.h (struct gdbarch_tdep): Change definition of ppc_fp0_regnum and ppc_fpscr_regnum: if they are -1, then this processor variant lacks those registers. (ppc_floating_point_unit_p): Change description to make it clear that this returns info about the ISA, not the ABI. * rs6000-tdep.c (ppc_floating_point_unit_p): Decide whether to return true or false by checking tdep->ppc_fp0_regnum and tdep->ppc_fpscr_regnum. 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.
