Check this for various operands of tagged types: +-- objects (declared or allocated), formal parameters, view conversions, +-- function calls (both primitive and non-primitive). +-- +-- TEST DESCRIPTION: +-- This test uses foundation F392C00 to test the usages of statically +-- tagged objects and values. The calls to Validate indicate the +-- expected sequence of procedure calls since the previous call to +-- Validate. Static tags can be determined at compile time, and +-- hence this is a test of correct overload resolution for tagged types. +-- A clever compiler which unrolls loops and does path analysis on +-- access values will be able to perform the same kind of determination +-- for all of the code in this test. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- F392C00.A (foundation code) +-- C392C05.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 19 Dec 94 SAIC Removed RM references from objective text. +-- 24 Oct 95 SAIC Updated for ACVC 2.0.1 +-- 13 Feb 97 PWB.CTA Corrected assumption that "or" operands are +-- evaluated in textual order. +--! + +with Report; +with TCTouch; +with F392C00_1; +procedure C392C05 is -- Hardware_Store + + package Switch renames F392C00_1; + + subtype Switch_Class is Switch.Toggle'Class; + + type Reference is access all Switch_Class; + + A_Switch : aliased Switch.Toggle; + A_Dimmer : aliased Switch.Dimmer; + An_Autodim : aliased Switch.Auto_Dimmer; + + type Light_Bank is array(Positive range <>) of Reference; + + Lamps : Light_Bank(1..3); + +begin -- Main test procedure. + + Report.Test ("C392C05", "Check that a dispatching subprogram call is " + & "determined by the controlling tag for statically " + & "tagged controlling operands" ); + +-- Check use of static tagged declared objects, +-- and static tagged formal parameters +-- Must call correct version of flip based on type of controlling op. + +-- Turn on the lights! + + Switch.Flip( A_Switch ); + TCTouch.Validate( "A", "Declared Toggle" ); + + Switch.Flip( A_Dimmer ); + TCTouch.Validate( "GBA", "Declared Dimmer" ); + + Switch.Flip( An_Autodim ); + TCTouch.Validate( "KGBA", "Declared Auto_Dimmer" ); + + Lamps(1) := new Switch.Toggle; + Lamps(2) := new Switch.Dimmer; + Lamps(3) := new Switch.Auto_Dimmer; + +-- Check use of static tagged allocated objects, +-- and static tagged formal parameters in a loop which may dynamically +-- dispatch.
