(struct gdbarch_tdep): Add fp_model. * arm-tdep.c (arm_gdbarch_init): Set fp_model in tdep. Defer setting up floating-point conversions until we know the floating-point model in use by the inferior. Don't complain about being unable to determine the ABI of the inferior when we don't have one. (arm_extract_return_value): Support different floating-point models. (arm_store_return_value): Likewise. * armnbsd-tdep.c (arm_netbsd_aout_init_abi): Set fp_model in tdep to ARM_FLOAT_SOFT. (arm_netbsd_elf_init_abi): Set fp_model to ARM_FLOAT_SOFT_VFP.
