* Initial version. * Make PGO feature optional off-by-default. Needs PGO_MODE environment variable to be set. Add -O3 -march=native tuning flags for better performance. * Adjust script to be more quiet. * Adjust max city length. Fix an issue when accumulating results. * Tune thomaswue submission. mmap the entire file, use Unsafe directly instead of ByteBuffer, avoid byte[] copies. These tricks give a ~30% speedup, over an already fast implementation. * Optimize parsing of numbers based on specific given constraints. * Fix for segment calculation for case of very small input. * Minor shell script fixes. * Separate out build step into file additional_build_step_thomaswue.sh, simplify run script and remove PGO option for now. * Minor corrections to the run script. --------- Co-authored-by: Alfonso² Peterssen <alfonso.peterssen@oracle.com>
