Hi,
I just tried spec2000(C/C++/F77) by using gcc 3.4.0, and 173.applu failed.
Here's the machines info and gcc config info:
> uname -a
Linux laplace 2.4.17-mckinley-smp #1 SMP Tue May 14 21:57:05 MDT 2002 ia64 unknown
> gcc -v
Configured with: ../gcc/configure --prefix=/home/qiongc/shared/ --enable-languages=c,c++,f77 --enable-shared --disable-libgcj
Thread model: posix
gcc version 3.4.0
> ld -v
GNU ld version 2.14 20030612
All of the benchmarks are compiled under "-O2".
Could anyone please tell me extra gcc flag to compile applu?
>From the following "applu.out.mis" file, it seems the problem is related
to some floating point options.
Thanks.
