Your contribution will likely be most welcomed. I encourage you to send the patch to fort...@gcc.gnu.org and gcc-patc...@gcc.gnu.org to open up discussion. For testcases, look in gcc/testsuite/gfortran.dg for files with the string 'pdt' in the name. Copy one of those and adjust it to suit your needs.
