commit r17-1793-g23aa47659828ae13898b76b1516f17fef8562a7e Author: Tobias Burnus <[email protected]> Date: Wed Jun 24 06:30:25 2026 +0200 libgomp: Handle omp_default_device in the fallback case [PR125951] Support for omp_default_device was added before the commit r17-1702-g8af1592882509f for the Linux case, but for the fallback case, it was missed - such that the testcase failed on all non-Linux systems. libgomp/ChangeLog: PR libgomp/125951 * target.c (omp_get_device_distances): Handle omp_default_device in the fallback code.
