DejaGnu's definition of ${tool}_load has an optional argument for flags
to pass to the test program, but none of the procedures in DejaGnu or in
gcc/testsuite/* are set up to pass such flags. It would be fairly
straightforward to provide a local version of gfortran_load to intercept
calls to the global one, and have it add flags specified with a new test
directive to the DejaGnu version of ${tool}_load. That directive could
be something like:
{ dg-program-options options [{ target selector }] }
Would something like this be useful for other languages as well, or is
Fortran the only one in GCC that has support to process a program's
command line?
I'm willing to implement something like this if it looks worthwhile.
