1-- LA140052.AM 2-- 3-- Grant of Unlimited Rights 4-- 5-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687, 6-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained 7-- unlimited rights in the software and documentation contained herein. 8-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making 9-- this public release, the Government intends to confer upon all 10-- recipients unlimited rights equal to those held by the Government. 11-- These rights include rights to use, duplicate, release or disclose the 12-- released technical data and computer software in whole or in part, in 13-- any manner and for any purpose whatsoever, and to have or permit others 14-- to do so. 15-- 16-- DISCLAIMER 17-- 18-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR 19-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED 20-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE 21-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE 22-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A 23-- PARTICULAR PURPOSE OF SAID MATERIAL. 24--* 25-- 26-- OBJECTIVE: 27-- Check that a compilation unit may not depend semantically on two 28-- different versions of the same compilation unit. Check the case 29-- where a generic package body depends on a generic package 30-- specification. 31-- 32-- TEST DESCRIPTION: 33-- This test compiles a generic package specification and body, 34-- followed by a procedure that makes a call to a procedure 35-- contained inside the generic package. Then, the generic package 36-- specification is recompiled, making the body of the generic 37-- package obsolete. Unless automatic recompilation is 38-- supported this test should fail to link. Otherwise, the test should 39-- recompile and link the correct version of the units and report 40-- "PASSED" at execution time. 41-- 42-- SPECIAL REQUIREMENTS: 43-- To build this test: 44-- 1) Compile the file LA140050 (and include the results in the 45-- program library). 46-- 2) Compile the file LA140051 (and include the results in the 47-- program library). 48-- 3) Compile the file LA140052 (and include the results in the 49-- program library). 50-- 4) Compile the file LA140053 (and include the results in the 51-- program library). 52-- 5) Attempt to build an executable image. 53-- 6) If an executable image results, run it. 54-- 55-- TEST FILES: 56-- This test consists of the following files: 57-- LA140050.A 58-- LA140051.A 59-- -> LA140052.AM 60-- LA140053.A 61-- 62-- PASS/FAIL CRITERIA: 63-- Expect a link-time error message that the body of generic 64-- package LA14005_1 is missing or obsolete. If automatic 65-- recompilation is supported, and an executable image is 66-- built, expect a "PASSED" message from execution. 67-- 68-- 69-- CHANGE HISTORY: 70-- 01 MAY 95 ACVC 1.12 LA5008I baseline version 71-- 09 MAY 95 SAIC Initial version 72-- 08 NOV 96 SAIC Unit naming correction 73-- 07 DEC 96 SAIC Moved spec of LA14005_1 to a separate file. 74-- 75--! 76 77package body LA14005_1 is 78 function return_flt return types.gen_flt is 79 begin 80 return types.gen_flt(types.TC_var); 81 end return_flt; 82begin 83 types.TC_var := types.flt(TC_constant_flt); 84end LA14005_1; 85 86 --------------------------------------------------------- 87 88with Report; use Report; 89with LA14005_0; 90with LA14005_1; 91procedure LA140052 is 92 subtype TC_flt is float digits 5; 93 94 package Y is new LA14005_0 (integer(100.0), integer(0.0), TC_flt); 95 package inst is new LA14005_1 (Y); 96 TC_var : TC_flt; 97begin 98 Test ("LA14005", "Check that a compilation unit may not depend " & 99 "semantically on two different versions of the same " & 100 "compilation unit.
