TME fpu problem
I guess some around here have already played with TME, and I may be
doing some stupid user mistake:
I've setup a TME instance emulating a sun3 160 (following the instructions
on the TME web page), and successfully installed NetBSD 6.1.2 on it.
Most things work fine, but when I run
it dies with:
Core was generated by `top'.
Program terminated with signal 8, Arithmetic exception.
#0 0x02078430 in floor () from /usr/lib/libm.so.0
and looking there:
(gdb) x/16i floor
0x2078406 <floor>: fmovel %fpcr,%d0
0x207840a <floor+4>: fmoved %sp@(4),%fp0
0x2078410 <floor+10>: fbun 0x2078434 <floor+46>
0x2078414 <floor+14>: fboge 0x2078422 <floor+28>
0x2078418 <floor+18>: fmovel #32,%fpcr
0x2078420 <floor+26>: bras 0x207842a <floor+36>
0x2078422 <floor+28>: fmovel #16,%fpcr
0x207842a <floor+36>: fintd %sp@(4),%fp0
=> 0x2078430 <floor+42>: fmovel %d0,%fpcr
0x2078434 <floor+46>: rts
0x2078436 <floor+48>: nop
(gdb) info reg d0
d0 0x0 0
So writing to the FP conroll register already worked before, but now restoring
the saved value fails?
Is this a TME bug, or did I miss something in the configuration?
