| | | | | | | | | | | | | | | | | | | | * sem_ch3.adb (Is_Visible_Component): Component is visible in a derived type if inherited through an ancestor that has a partial view of the original type holding the component, if the full view of that original type is in scope. * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs. 2015-05-28 Bob Duff <duff@adacore.com> * sem_util.adb (Requires_Transient_Scope): For definite untagged subtypes, we should never have to use the secondary stack. This moves toward that goal. But there are still cases that don't work. Here, we move the check for Is_Definite first, but add a special-purpose check for Has_Discrim_Dep_Array. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@223817 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | * sem_util.adb (Wrong_Type): In any instance, do not emit error if type of expression is the partial view of the expected type. 2015-05-28 Ed Schonberg <schonberg@adacore.com> * sem_res.adb (Resolve_Actuals): a) The replacement of formal names in named associations only needs to be done within an instance, on a call to a primitive of a formal derived type, where the actual subprogram may have different formal names than those of the primitive operation of the formal type. b) Defaulted parameters must be taken into account when obtaining the names of the formals of the actual subprogram being called. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@223804 138bc75d-0d04-0410-961f-82ee72b054a4

Remove obsolete comments about those init_procs -- init_procs for such types are no longer complex. A typical init_proc just initializes the 'Tag field, and calls the parent init_proc (e.g. for Limited_Controlled), which calls the grandparent (for Root_Controlled), which does nothing. This all boils down to one instruction when inlined. * exp_ch7.adb (Create_Finalizer): Inline the finalizer. 2015-05-28 Ed Schonberg <schonberg@adacore.com> * sem_ch4.adb (Analyze_Selected_Component): If the type to use is a derived type and is a generic actual, the selected component appears within an instance body, and the check over the type has failed, examine ancestor types for the desired component. (Find_Component_In_Instance): If record type is a derived type, examine all ancestors in order to locate desired component. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@223800 138bc75d-0d04-0410-961f-82ee72b054a4
