--- Comment #5 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Rainer Orth from comment #0) > * Despite -save-temps, the lto-wrapper input objects are removed at the end, > so I cannot manually rerun lto-wrapper to investigate. You could modify gcc/testsuite/gcc.misc-tests/outputs.exp to: * only run a single 'outest' which is failing (e.g. comment all 'outest' lines but 'outputs lto st mult dumpdir named') * Remove 'file delete' in 'proc outest' Run the test and check which files are under /tmp + test directory - and compare it with the failing while (which checks with 'file exists' or using 'glob').
