--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-09-05 07:42:29 UTC --- Parser patch: http://gcc.gnu.org/ml/fortran/2011-09/msg00002.html TODO as follow up: * Replace "Sorry" by a real implementation in trans-stmt.c Note: Needs support for MASK= as allowed by the for-all header, reusing trans_forall will not work - and will generate slow code. * Implement type-spec support for "forall" and "do concurrent": "(integer(8) :: i = 1:5:2)" * Add documentation to gfc-internal.texi, update gfortran.texi (F2003 status) and the wiki * Try to make use of the constraints for the middle end (optimization, autoparallelization), if possible. As Cilk+ does something like that, one can piggyback on their effort, either after Cilk+ is merged or by forward porting the change from the Cilk+ branch to the trunk. Cf. http://gcc.gnu.org/ml/gcc/2011-09/msg00021.html and http://gcc.gnu.org/ml/gcc/2011-08/msg00279.html * Optionally (-fdo-concurrent=...?), parallelize the loop (e.g. by adding OpenMP pragmas).
