Bug ID: 80661 Summary: make check-gcc RUNTESTFLAGS="dg.exp=g*" runs all the tests in gcc.dg Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: testsuite Assignee: unassigned at gcc dot gnu.org Reporter: dominiq at lps dot ens.fr Target Milestone: --- It is my understanding that the command make check-gcc RUNTESTFLAGS="dg.exp=a*" runs all the tests in gcc.dg starting with an 'a' (same thing for g++ and gfortran). AFAICT (on darwin) this is true except when 'a' is replaced with 'g', 'o', or 't' (all the letters tested with gfortran). Is anybody understanding what is special with these three letters?
