+
+ Add support for SSE registers in core files.
+ * corelow.c (get_core_register_section): New function.
+ (get_core_registers): Fetch the new ".reg-xfp" sections,
+ in addition to the traditional ".reg" and ".reg2" sections.
+ Check for per-thread variants of all three. Use
+ get_core_register_section, instead of writing it out over and over
+ again.
+ * i386-linux-nat.c (i386_linux_fetch_core_registers): New function.
+ (i386_linux_nat_core_fns): New core_fns structure. We do our own
+ core handling now, instead of using the generic code in core-regset.c.
+ (_initialize_i386_linux_nat): New function, needed to register
+ i386_linux_nat_core_fns.
+ * config/i386/linux.mh (NATDEPFILES): Remove core-regset.o;
+ i386-linux-nat.c has its own sniffer now.
+ * gdbcore.h: (struct core_fns): Doc fix.
+
+ * i386v-nat.c (i386_float_info): Definition is #if 0'd; delete it
+ altogether. This should use the function i387-tdep.c.

+ Patch from Mark Kettenis <kettenis@gnu.org>:

+ * config/i386/tm-i386.h (FLOAT_INFO): New define.
+ * i387-tdep.c (print_i387_value, print_i387_ext,
+ print_i387_status_word, print_i387_control_word, i387_float_info):
+ New functions, used to implement generic `info float' command.
