commit r13-8449-g8c4785e77e8b54109fbb4f81a3b624e98184c2aa Author: Sam James <s...@gentoo.org> Date: Fri Mar 8 15:24:20 2024 +0100 contrib: Improve dg-extract-results.sh's Python detection [PR109668] 'python' on some systems (e.g. SLES 15) might be Python 2. Prefer python3, then python, then python2 (as the script still tries to work there). PR other/109668 * dg-extract-results.sh: Check for python3 before python. Check for python2 last.
