PR fortran/40011
* error.c : Add static flag 'warnings_not_errors'.
(gfc_error): If 'warnings_not_errors' is set, branch to code
from gfc_warning.
(gfc_clear_error): Reset 'warnings_not_errors'.
(gfc_errors_to_warnings): New function.
* options.c (gfc_post_options): If pedantic and flag_whole_file
change the latter to a value of 2.
* parse.c (parse_module): Add module namespace to gsymbol.
(resolve_all_program_units): New function.
(clean_up_modules): New function.
(translate_all_program_units): New function.
(gfc_parse_file): If whole_file, do not clean up module right
away and add derived types to namespace derived types. In
addition, call the three new functions above.
* resolve.c (not_in_recursive): New function.
(not_entry_self_reference): New function.
(resolve_global_procedure): Symbol must not be IFSRC_UNKNOWN,
procedure must not be in the course of being resolved and
must return false for the two new functions. Pack away the
current derived type list before calling gfc_resolve for the
gsymbol namespace. It is unconditionally an error if the ranks
of the reference and ther procedure do not match. Convert
errors to warnings during call to gfc_procedure_use if not
pedantic or legacy.
(gfc_resolve): Set namespace resolved flag to -1 during
resolution and store current cs_base.
* trans-decl.c (gfc_get_symbol_decl): If whole_file compilation
substitute a use associated variable, if it is available in a
gsymbolnamespace.
(gfc_get_extern_function_decl): If the procedure is use assoc,
do not attempt to find it in a gsymbol because it could be an
interface. If the symbol exists in a module namespace, return
its backend_decl.
* trans-expr.c (gfc_trans_scalar_assign): If a derived type
assignment, set the rhs TYPE_MAIN_VARIANT to that of the rhs.
* trans-types.c (copy_dt_decls_ifequal): Add 'from_gsym' as a
boolean argument. Copy component backend_decls directly if the
components are derived types and from_gsym is true.
(gfc_get_derived_type): If whole_file copy the derived type from
the module if it is use associated, otherwise, if can be found
in another gsymbol namespace, use the existing derived type as
the TYPE_CANONICAL and build normally.
* gfortran.h : Add derived_types and resolved fields to
gfc_namespace. Include prototype for gfc_errors_to_warnings.
