660 * trans-expr.c (gfc_conv_procedure_call): With a non-copying
661 procedure argument (eg TRANSPOSE) use a temporary if there is
662 any chance of aliasing due to host or use association.

664 results and do not use a temporary for implicitly PURE
665 variables. Use a temporary for Cray pointees.

667 implicit pureness of containing procedure.
668 * decl.c (match_old_style_init, gfc_match_data): Where decl
669 would fail in PURE procedure, set implicit_pure to zero.
670 * gfortran.h : Add implicit_pure to structure symbol_attr and
671 add prototype for function gfc_implicit_pure.
672 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
673 Where decl would fail in PURE procedure, reset implicit_pure.

675 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
676 * match.c (gfc_match_critical, gfc_match_stopcode,
677 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
679 * parse.c (decode_omp_directive): The same.

682 resolve_function, resolve_ordinary_assign) : The same.
683 (gfc_implicit_pure): New function.
684 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
685 to ab_attribute enum and use it in this function.

691 make static and move in front of its only caller, to ...
692 * trans-array.c (symbols_could_alias): ... here.
693 Pass information about pointer and target status as
694 arguments. Allocatable arrays don't alias anything
695 unless they have the POINTER attribute.
696 (gfc_could_be_alias): Keep track of pointer and target
697 status when following references. Also check if typespecs
698 of components match those of other components or symbols.

748 check for duplicate occurence of allocation/deallocation objects.

760 routine to make sure it receives module name mangling.
