You sure you want to enter into the tricky world of SPEC testing, where the only way to speed up your compiler is by knowing non-disclosed secrets of CPU's and by in depth studies on optimizations of programs that other than for SPEC really have very little to do with real world optimizations?
That's all so specialistic and fulltime work - where to start? Kind Regards, Vincent Diepeveen On Fri, 5 Jun 2015, Mikhail Maltsev wrote:
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? 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? -- Regards, Mikhail Maltsev
