Actually, this is the EEMBC version with bezier01, where the entire benchmark
gets optized away and thus tiny changes in the cost of the set-up code make
noticeable differences. Comparing the geometric means with bezier01 left out
gives:
automotive: 5.73% improvement
consumer: 0.04% improvement
networking: 0.37% improvement
office: 0.90% worse
telecom: 0.00% worse
