All, Attached please find what I hope is the final version of the patch that adds partial support for teams of images, the last remaining major Fortran 2018 feature without current support in gfortran (or any other Fortran compiler of which I’m aware). I submitted the first draft of this patch last September. Regression tests show no unexpected failures (i.e., the output of ‘grep -w FAIL gfortran.sum’ is empty). The Changelogs are below.
Among the details remaining for future commits are the following: support for the GET_TEAM intrinsic function is incomplete, the TEAM_NUMBER intrinsic function doesn’t yet accept the optional argument, and a SYNC TEAM test is needed. Using any of the unsupported features generates a compile-time error message from gfortran or a runtime error message from OpenCoarrays. There are no internal compiler errors of which I’m aware. And there remains one big, dissertation-worthy project in handling the use of teams in the presence of failed images. Ok for trunk?
