branch: master
commit 55f92d87e3083b3f9873b4df99725a51606dbaae
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Record gcc version twelve pc-linux-gnu speed for commit 5a4fcaed7
    
    Compared to the immediately preceding commit, upgrading gcc from version
    eleven to twelve with no other change causes a 20-30% speed regression
    for solves, whereas "no solve" scenarios are unaffected.
    
    Results using commit 5a4fcaed7 of 2022-08-18T16:22:15.
