Based on the ML automatic search technology, through multiple iterations, the optimal option is found in the optimizable space, and then the target program with better performance is compiled.

  • Performance – test environment:
  • OS: OpenEuler 20.03
  • CPU: Kunpeng 920

The Bisheng compiler development team conducted performance evaluation based on the Bisheng compiler version 2.1.0. The SPEC CPU 2017 test report showed that the Bisheng compiler 2.1.0 achieved a comprehensive score of 399 points, and the GCC 9.3.0 comprehensive score was 321 points. Under the same hardware and software environment, the performance of Bisheng compiler is 24.3% higher than that of GCC.
