ppc64 gdb register problem |

Hi,
I've had this
problem show up in several 64 bit (ppc64) Linux versions 2.6.4 through
2.6.9. When debugging a program compiled for 64 bits (gcc -m64) The
debugger is unable to display the contents of the fpscr register (info reg
fpscr, or info reg all). Gdb says :
fpscr reading
register fpscr (#70) Input/output error.
This would just be
irritating, except a program I'm trying to debug, an infiniband verb layer app,
fails to load in gdb with:
Error while reading
shared library symbols:
reading register
fpscr (#70); Input/output error.
The details of what
I'm running are:
PowerMac
G5
uname
-a
Linux g5linux1
2.6.9.0-ydl.1.custom #1 SMP ppc64 ppc64 ppc64 GNU/Linux
gcc
-v
gcc version
3.3.3
gdb
-v
6.1.post-1.20040607.41rh
and the same results
with:
6.2
This is repeatable
with a simple hello world program. Break in main, and do info reg
fpscr.
I haven't been able
to find any reference to this problem anywhere else.
Anyone have any
ideas?
Thanks!
