+ * procfs.c, core-svr4.c: Move fetch_core_registers from procfs.c
+ to new file core-svr4.c.

+
+This version of fetch_core_registers() is used by most systems that
+implement /proc. For these systems, the general registers are laid out
+the same way in both the core file and the gregset_p structure. The
+current exception to this is Irix-4.*, where the gregset_p structure is
+split up into two pieces in the core file.
+
+The general register and floating point register sets are manipulated by
+separate ioctl's. This file makes the assumption that if FP0_REGNUM is
+defined, then support for the floating point register set is desired,
+regardless of whether or not the actual target has floating point hardware.
