[Bug c/28644] New: 400.perlbench never completes when compiled with -O3

[uttam_p at yahoo dot com]

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

4.1.0 is getting old and 4.1.1 has been released with bugs fixed.  And this bug
really has no info about what the problem is.
