From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; 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 files in the upstream repository. --- gcc/testsuite/ada/acats/tests/cd/cd30002.a | 207 +++++++++++++++++++++++++++++ 1 file changed, 207 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cd/cd30002.a (limited to 'gcc/testsuite/ada/acats/tests/cd/cd30002.a') diff --git a/gcc/testsuite/ada/acats/tests/cd/cd30002.a b/gcc/testsuite/ada/acats/tests/cd/cd30002.a new file mode 100644 index 000000000..7b6fff713 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cd/cd30002.a @@ -0,0 +1,207 @@ +-- CD30002.A +-- +-- Grant of Unlimited Rights +-- +-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687, +-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained +-- unlimited rights in the software and documentation contained herein. +-- Unlimited rights are defined in DFAR 252.227-7013(a)(19).

It then checks the alignments by +-- declaring some objects, and checking that the integer values of +-- their addresses is mod the specified alignment. This will not +-- prevent false passes where the lucky compiler gets it right by +-- chance, but will catch compilers that specifically do not obey +-- the alignment clauses. +-- +-- APPLICABILITY CRITERIA: +-- All implementations must attempt to compile this test. +-- +-- For implementations validating against Systems Programming Annex (C): +-- this test must execute and report PASSED. +-- +-- For implementations not validating against Annex C: +-- this test may report compile time errors at one or more points +-- indicated by "-- ANX-C RQMT", in which case it may be graded as inapplicable. +-- Otherwise, the test must execute and report PASSED. +-- +-- +-- CHANGE HISTORY: +-- 22 JUL 95 SAIC Initial version +-- 09 MAY 96 SAIC Strengthened for 2.1 +-- 26 FEB 97 PWB.CTA Allowed for unexpected word sizes +-- 16 FEB 98 EDS Modified documentation. +-- 26 SEP 98 RLB Fixed value on line 130 so check and dec. match. +-- 30 OCT 98 RLB Split Multiple_Alignment and revised the +-- calculation to work on all targets. +-- 18 JAN 99 RLB Repaired again to work on targets where word size +-- equals storage unit. +--! + +----------------------------------------------------------------- CD30002_0 + +with Impdef; +with System.Storage_Elements; +package CD30002_0 is + + S_Units_per_Word : constant := System.Word_Size/System.Storage_Unit; + -- Must be 1 or greater. + + Multiple_Type_Alignment : constant := + Integer'Min ( Impdef.Max_Default_Alignment, + 2 * S_Units_per_Word ); + -- Calculate a reasonable alignment, but not larger than the + -- implementation is required to support. + + Multiple_Object_Alignment : constant := + Integer'Min ( Impdef.Max_Linker_Alignment, + 2 * S_Units_per_Word ); + -- Calculate a reasonable object alignment, but not larger than + -- the implementation is required to support. + + Small_Alignment : constant := + Integer'Max ( S_Units_per_Word / 2, 1); + -- Calculate a reasonable small alignment, but not less than 1. + -- (If S_Units_per_Word = 1, 1/2 => 0 which causes problems + -- verifying alignment.) + + subtype Storage_Element is System.Storage_Elements.Storage_Element; + + type Some_Stuff is array(1..S_Units_Per_Word) of Storage_Element; + for Some_Stuff'Alignment + use Impdef.Max_Default_Alignment; -- ANX-C RQMT. + + Library_Level_Object : Some_Stuff; + for Library_Level_Object'Alignment + use Impdef.Max_Linker_Alignment; -- ANX-C RQMT. + + type Quarter is mod 4; -- two bits + for Quarter'Alignment use Small_Alignment; -- ANX-C RQMT. + + type Half is mod 16; -- nibble + for Half'Alignment use Multiple_Type_Alignment; -- ANX-C RQMT. + + type O_Some_Stuff is array(1..S_Units_Per_Word) of Storage_Element; + + type O_Quarter is mod 4; -- two bits + + type O_Half is mod 16; -- nibble + +end CD30002_0; + +-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- + +-- there is no package body CD30002_0 + +------------------------------------------------------------------- CD30002 + +with Report; +with Impdef; +with CD30002_0; +with System.Storage_Elements; +procedure CD30002 is + + My_Stuff : CD30002_0.Some_Stuff; + -- Impdef.Max_Default_Alignment + + My_Quarter : CD30002_0.Quarter; + -- CD30002_0.S_Units_per_Word / 2 + + My_Half : CD30002_0.Half; + -- CD30002_0.S_Units_per_Word * 2 + + Stuff_Object : CD30002_0.O_Some_Stuff; + for Stuff_Object'Alignment + use Impdef.Max_Default_Alignment; -- ANX-C RQMT. + + Quarter_Object : CD30002_0.O_Quarter; + for Quarter_Object'Alignment + use CD30002_0.Small_Alignment; -- ANX-C RQMT. + + Half_Object : CD30002_0.O_Half; + for Half_Object'Alignment + use CD30002_0.Multiple_Object_Alignment; -- ANX-C RQMT. + + subtype IntAdd is System.Storage_Elements.Integer_Address; + use type System.Storage_Elements.Integer_Address; + + function A2I(Value: System.Address) return IntAdd renames + System.Storage_Elements.To_Integer; + + NAC : constant String := " not aligned correctly"; + +begin -- Main test procedure. + + Report.Test ("CD30002", "Check that the implementation supports " & + "Alignments for subtypes and objects specified " & + "as factors and multiples of the number of " & + "storage elements per word, unless those values " & + "cannot be loaded and stored.
