+
+       * rs6000.h (struct rs6000_args): Add sysv_gregno.
+       * rs6000.c (init_cumulative_args): Init sysv_gregno.
+       (function_arg_boundary): Align DFmode.
+       (function_arg_advance): Restructure for ABI_V4; use sysv_gregno
+       to get fp reg and stack overflow correct.
+       (function_arg): Likewise.
+       (function_arg_pass_by_reference): True for TFmode for ABI_V4.
+       (setup_incoming_varargs): Restructure for ABI_V4; use 
+       function_arg_advance to skip final named argument.
+       (expand_builtin_saveregs): Properly unskip the last integer arg
+       when doing varargs.  Adjust overflow location calculation.
+
+       * ginclude/va-ppc.h (struct __va_list_tag): Make gpr and fpr 
+       explicitly unsigned.
+       (__VA_FP_REGSAVE): Use new OFS argument instead of AP->fpr directly.
+       (__VA_GP_REGSAVE): Similarly.
+       (__va_longlong_p): Delete.
+       (__va_arg_type_violation): New declaration.
+       (va_arg): Restructure.  Flag promotion errors.  Align double. 
+       TFmode passed by reference.
+
+       * rs6000.md (movdi_32+1): Use GEN_INT after arithmetic
+       in the HOST_BITS_PER_WIDE_INT > 32 case.

        * dwarf2out.c (output_abbrev_section): Terminate with a zero.
