Hi,

I've been trying to run perlbench (speccpu 2006 benchmark) compiled with gcc 4.1.0 with "-O3 -ffast-math -funroll-all-loops -m64". But when I run this benchmark, it never completes (it goes on more than 3 hours) and I'd to kiil it.
It completes when I added -fno-inline option. Just wanted to report this as a possible problem in the inliner.

GCC has been configured as shown below.

Configured with: ../configure --enable-threads=posix --prefix=/usr --with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man --enable-languages=c,c++ --disable-checking --libdir=/usr/lib64 --enable-libgcj --with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib64 --with-system-zlib --enable-shared --enable-__cxa_atexit x86_64-suse-linux
Thread model: posix
gcc version 4.1.0 

Processor: AMD Opteron
