shows that gcc 4.1 has been failing vortex in SPEC CPU 2000 on
Linux/EM64T and Linux/PPC64 at least since Aug. 7, 2005. The current
gcc 4.1 also failed vortex on Linux/ia64. Is that a known issue?
Yes this is an aliasing violation inside of the sources of vortex
see PR 23449.
Note 127.gcc has similar issues too but I don't know why nobody have
brought this up to SPEC. I was trying to get Apple to do it a couple
of years ago and then trying to get SUSE to do it but I could never get
anyone with enough courage to propose my fix of using memset instead of
casting.
Thanks,
