I note that a few of the tests in gcc testsuite are marked to show stabs tests as unsupported: pr35154.c:/* { dg-skip-if "No stabs" { mmix-*-* alpha*-*-* hppa*64*-*-* ia64-*-* *-*-vxworks* } { "*" } { "" } } */ pr35154.c:/* { dg-skip-if "stabs only" { *-*-* } { "*" } { "-gstabs" } } */ Why are there hundreds of tests which aren't so marked and fail on targets which lack stabs support? Are we expected to edit out the failure lines which include stabs before sending to gcc-testresults? What about coff tests? I've seen (in the distant past) recommendation to set -g3 -gdwarf-2 for running certain profilers on Windows, but I don't think that is an "official" recommendation.
