Pentium III.
>Description:
Sometime between 20020114T042927Z and 20020118080805Z,
gcore.exp started failing on x86-linux.  The symptom is that
after loading the core file, the XMM registers print as
xmm0           {f = {0x0, 0x0, 0x0, 0x0}}       {f = {-nan(0x7fffff), -nan(0x7fffff), -nan(0x7fffff), -nan(0x7fffff)}}
rather than
xmm0           {f = {0x0, 0x0, 0x0, 0x0}}       {f = {0, 0, 0, 0}}
the second is the historical behaviour.
>How-To-Repeat:
make check
>Fix:
I suspect this change:

2002-01-19  Mark Kettenis  <kettenis@gnu.org>

        * i386gnu-nat.c: Include "i386-tdep.h".
        (fetch_fpregs): Simplify code dealing with uninitialized floating
        point states such that it doesn't require FP7_REGNUM.

but have not tried backing it out to see if the problem goes away.
