+ * configure.srv (powerpc*-*-linux*): Add ISA 2.05 object files and
+ XML target descriptions.
+ * linux-ppc-low.c (ppc_arch_setup): Init registers with 64-bit FPSCR
+ when inferior is running on an ISA 2.05 or later processor. Add
+ special case to return offset for full 64-bit slot of FPSCR when
+ in 32-bits.

* Makefile.in (SFILES, clean): Added sparc64 files.
