obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective

Check that, for +-- a primitive subprogram of the private extension that is inherited from +-- the ancestor type and not overridden, the formal parameter names and +-- default expressions come from the corresponding primitive subprogram +-- of the ancestor type, while the body comes from that of the parent +-- type. Check both dispatching and non-dispatching cases. +-- +-- TEST DESCRIPTION: +-- Consider: +-- +-- package P is +-- type Ancestor is tagged ... +-- procedure Op (P1: Ancestor; P2: Boolean := True); +-- end P; +-- +-- with P; +-- package Q is +-- type Derived is new P.Ancestor with ... +-- procedure Op (X: Ancestor; Y: Boolean := False); +-- end Q; +-- +-- with P, Q; +-- package R is +-- type Priv_Ext is new P.Ancestor with private; -- (A) +-- -- Inherits procedure Op (P1: Priv_Ext; P2: Boolean := True); +-- -- But body executed is that of Q.Op. +-- private +-- type Priv_Ext is new Q.Derived with record ... -- (B) +-- end R; +-- +-- The ancestor type in (A) differs from the parent type in (B); the +-- parent of the full type is descended from the ancestor type of the +-- private extension. For a call to Op (from outside the scope of the +-- full view) with an operand of type Priv_Ext, the formal parameter +-- names and default expression come from that of P.Op (the ancestor +-- type's version), but the body executed will be that of +-- Q.Op (the parent type's version) +-- +-- One half of the test mirrors the above template, where an inherited +-- subprogram (Set_Display) is called using the formal parameter +-- name (C) and default parameter expression of the ancestor type's +-- version (type Clock), but the version of the body executed is from +-- the parent type. +-- +-- The test also includes an examination of the dynamic evaluation +-- case, where correct body associations are required through dispatching +-- calls. As described for the non-dispatching case above, the formal +-- parameter name and default values of the ancestor type's (Phone) +-- version of the inherited subprogram (Answer) are used in the +-- dispatching call, but the body executed is from the parent type. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +package C730001_0 is + + type Display_Kind is (None, Analog, Digital); + type Illumination_Type is (None, Light, Phosphorescence); + type Capability_Type is (Available, In_Use, Call_Waiting, Conference); + type Indicator_Type is (None, Light, Bell, Buzzer, Click, Modem); + + type Clock is abstract tagged record -- ancestor type associated + Display : Display_Kind := None; -- with non-dispatching case. + Illumination : Illumination_Type := None; + end record; + + type Phone is tagged record -- ancestor type associated + Status : Capability_Type := Available; -- with dispatching case. + Indicator : Indicator_Type := None; + end record; + + -- The Set_Display procedure for type Clock implements a basic, no-frills + -- clock display. + procedure Set_Display (C : in out Clock; + Disp: in Display_Kind := Digital); + + -- The Answer procedure for type Phone implements a phone status change + -- operation. + procedure Answer (The_Phone : in out Phone; + Ind : in Indicator_Type := Light); + -- ...Other general clock and/or phone operations (not specified in this + -- test scenario). + +end C730001_0; + + + --==================================================================-- + + +package body C730001_0 is + + procedure Set_Display (C : in out Clock; + Disp: in Display_Kind := Digital) is + begin + C.Display := Disp; + C.Illumination := Light; + end Set_Display; + + procedure Answer (The_Phone : in out Phone; + Ind : in Indicator_Type := Light) is + begin + The_Phone.Status := In_Use; + The_Phone.Indicator := Ind; + end Answer; + +end C730001_0; + + + --==================================================================-- + + +with C730001_0; use C730001_0; +package C730001_1 is + + type Power_Supply_Type is (Spring, Battery, AC_Current); + type Speaker_Type is (None, Present, Adjustable, Stereo); + + type Wall_Clock is new Clock with record + Power_Source : Power_Supply_Type := Spring; + end record; + + type Office_Phone is new Phone with record + Speaker : Speaker_Type := Present; + end record; + + -- Note: Both procedures below, parameter names and defaults differ from + -- parent's version. + + -- The Set_Display procedure for type Wall_Clock improves upon the + -- basic Set_Display procedure of type Clock. + + procedure Set_Display (WC: in out Wall_Clock; + D : in Display_Kind := Analog); + + procedure Answer (OP : in out Office_Phone; + OI : in Indicator_Type := Buzzer); + + -- ...Other wall clock and/or Office_Phone operations (not specified in + -- this test scenario). + +end C730001_1; + + + --==================================================================-- + + +package body C730001_1 is + + -- Note: This body is the one that should be executed in the test block + -- below, not the version of the body corresponding to type Clock. + + procedure Set_Display (WC: in out Wall_Clock; + D : in Display_Kind := Analog) is + begin + WC.Display := D; + WC.Illumination := Phosphorescence; + end Set_Display; + + + procedure Answer (OP : in out Office_Phone; + OI : in Indicator_Type := Buzzer) is + begin + OP.Status := Call_Waiting; + OP.Indicator := OI; + end Answer; + +end C730001_1; + + + --==================================================================-- + + +with C730001_0; use C730001_0; +with C730001_1; use C730001_1; +package C730001_2 is + + type Alarm_Type is (Buzzer, Radio, Both); + type Video_Type is (None, TV_Monitor, Wall_Projection); + + type Alarm_Clock is new Clock with private; + -- Inherits proc Set_Display (C : in out Clock; + -- Disp: in Display_Kind := Digital); -- (A) + -- + -- Would also inherit other general clock operations (if present). + + + type Conference_Room_Phone is new Office_Phone with record + Display : Video_Type := TV_Monitor; + end record; + + procedure Answer (CP : in out Conference_Room_Phone; + CI : in Indicator_Type := Modem); + + + function TC_Get_Display (C: Alarm_Clock) return Display_Kind; + function TC_Get_Display_Illumination (C: Alarm_Clock) + return Illumination_Type; + +private + + -- ...however, certain of the wall clock's operations (Set_Display, in + -- this example) improve on the implementations provided for the general + -- clock.
