From 60718890ae203c5e84c8b90f13763bf7a87e7afb Mon Sep 17 00:00:00 2001
From: jdp <jdp@FreeBSD.org>
Date: Mon, 14 Sep 1998 22:43:40 +0000
Subject: Add new functions fill_fpregs() and set_fpregs(), like fill_regs()
 and set_regs() but for the floating point register state.  The code is stolen
 from procfs_machdep.c, and moved out of there into machdep.c.

These functions are needed for generating ELF core dumps.
