+This file 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.

+GLOBAL FUNCTION
+
+	fetch_core_registers -- fetch current registers from core file
+
+SYNOPSIS
+
+	void fetch_core_registers (char *core_reg_sect,
+					  unsigned core_reg_size,
+					  int which, unsigned in reg_addr)
+
+DESCRIPTION
+
+	Read the values of either the general register set (WHICH equals 0)
+	or the floating point register set (WHICH equals 2) from the core
+	file data (pointed to by CORE_REG_SECT), and update gdb's idea of
+	their current values.  The CORE_REG_SIZE parameter is ignored.
+
+NOTES
+
+	Use the indicated sizes to validate the gregset and fpregset
+	structures.
