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

675 results and do not use a temporary for implicitly PURE
676 variables. Use a temporary for Cray pointees.

681 * gfortran.h : Add implicit_pure to structure symbol_attr and
682 add prototype for function gfc_implicit_pure.
683 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
684 Where decl would fail in PURE procedure, reset implicit_pure.

686 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.

693 resolve_function, resolve_ordinary_assign) : The same.
694 (gfc_implicit_pure): New function.
695 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE

702 make static and move in front of its only caller, to ...
703 * trans-array.c (symbols_could_alias): ... here.
704 Pass information about pointer and target status as
705 arguments. Allocatable arrays don't alias anything
706 unless they have the POINTER attribute.
707 (gfc_could_be_alias): Keep track of pointer and target
708 status when following references. Also check if typespecs
709 of components match those of other components or symbols.
