Please ignore this. It was sent by my evil twin. I think that the following patch takes care of everything (the diff I sent wasn't even connecting the new definitions): commit a14ee758af464230ab40c1a0d9adb4c7db34a9fc Author: Joseph Myers Date: Thu Nov 8 00:08:48 2007 +0000 include: 2007-11-07 Joseph Myers Daniel Jacobowitz * floatformat.h (struct floatformat): Add split_half field. (floatformat_ibm_long_double): New. libiberty: 2007-11-07 Joseph Myers Daniel Jacobowitz * floatformat.c (mant_bits_set): New. (floatformat_to_double): Use it. Note no special handling of split formats. (floatformat_from_double): Note no special handing of split formats. (floatformat_ibm_long_double_is_valid, floatformat_ibm_long_double): New. (floatformat_ieee_single_big, floatformat_ieee_single_little, floatformat_ieee_double_big, floatformat_ieee_double_little, floatformat_ieee_double_littlebyte_bigword, floatformat_vax_f, floatformat_vax_d, floatformat_vax_g, floatformat_i387_ext, floatformat_m68881_ext, floatformat_i960_ext, floatformat_m88110_ext, floatformat_m88110_harris_ext, floatformat_arm_ext_big, floatformat_arm_ext_littlebyte_bigword, floatformat_ia64_spill_big, floatformat_ia64_spill_little, floatformat_ia64_quad_big, floatformat_ia64_quad_little): Update for addition of split_half field. gdb: 2007-11-07 Joseph Myers Daniel Jacobowitz * gdbtypes.c (floatformats_ibm_long_double): New. * gdbtypes.h (floatformats_ibm_long_double): Declare. * ia64-tdep.c (floatformat_ia64_ext): Update for addition of split_half field. * mips-tdep.c (n32n64_floatformat_always_valid, floatformat_n32n64_long_double_big, floatformats_n32n64_long): Remove. (mips_gdbarch_init): Use floatformats_ibm_long_double instead of floatformats_n32n64_long. * ppc-linux-tdep.c (ppc_linux_init_abi): Use 128-bit IBM long double. * doublest.c (convert_floatformat_to_doublest, convert_doublest_to_floatformat): Handle split floating-point formats. * ppc-sysv-tdep.c (ppc_sysv_abi_push_dummy_call): Handle IBM long double arguments.
