So, prior to this commit, exactly 5 tests were compiled, which takes on the order of 3 seconds on this old hardware (see below). Now, with libgomp not respecting RUNTESTFLAGS (or not receiving RUNTESTFLAGS from make in obj/), building all libgomp takes 15 minutes. % time gmake check-fortran RUNTESTFLAGS="dg.exp=pr88249.f90" 886.46 real 746.40 user 132.63 sys > I have no idea what to change it to support what you want though, I'd suggest > just do > make -C gcc check-gfortran RUNTESTFLAGS="dg.exp=pr88269.f90" if you want to > check something in the GCC testsuite, not use the toplevel check-fortran. I have no idea how to fix the problem, but your suggested workaround seems to work. % time gmake -C gcc check-fortran RUNTESTFLAGS="dg.exp=pr88249.f90" ... === gfortran Summary === # of expected passes 5 /usr/home/kargl/gcc/obj/gcc/gfortran version 9.0.0 20181202 \ (experimental) (GCC) gmake[1]: Leaving directory '/usr/home/kargl/gcc/obj/gcc' gmake: Leaving directory '/usr/home/kargl/gcc/obj/gcc' 2.56 real 1.72 user 0.76 sys
