Andrew,
OK, I installed stock gnu gcc 3.4.6:
78n04 TEST/MMBENCH_PPC> ~/local/gcc-3.4.6/bin/gcc -v
Reading specs from
/u/noibm122/local/gcc-3.4.6/lib/gcc/powerpc64-unknown-linux-gnu/3.4.6/specs
Configured with: ../configure --prefix=/u/noibm122/local/gcc-3.4.6
--enable-languages=c
Thread model: posix
gcc version 3.4.6
and I get the exact same behavior as with the modified gcc 3 (it accepts the
power5 flags and everything). So, it would seem something that used to work in
the stock gcc is now broken . . .
Thanks,
Clint
