When I'm working on a particular area of gfortran, I tend
to use RUNTESTFLAGS to limit what is tested. For example,
I just fixed SPREAD() for scalar source and ncopies < 1.
I do
% cd obj
% gmake
% cd gcc
% gmake check-fortran RUNTESTFLAGS="dg.exp=spread\*.f90"
This only runs 63 tests. Of course, for final testing
I do a full regression test.
