Hi, all! Could anyone please share some tips/recommendations w.r.t. testing performance of code generated by GCC using SPEC CPU2006 benchmark (e.g. recommended configs and patches for SPEC sources, if needed). For example, 400.perlbench fails to link (GCC complains on multiple definition of some string-related functions, like here: https://vmakarov.fedorapeople.org/spec/spec2006.toolbox/gcc/log/20150117/747.log). Is there a workaround?
For this particular issue, I believe it is because GCC 5 has moved to a newer default C standard. Try adding -std=gnu89 to the CPORTABILITY flags of perbench. Kyrill
Also, I noticed that Vladimir stopped publishing SPEC 2006 results in January 2015 (though current SPEC 2000 results are available). Is there some policy on publishing benchmark results?
