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/cxb/cxb30132.am | 205 ++++++++++++++++++++++++++ 1 file changed, 205 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cxb/cxb30132.am (limited to 'gcc/testsuite/ada/acats/tests/cxb/cxb30132.am') diff --git a/gcc/testsuite/ada/acats/tests/cxb/cxb30132.am b/gcc/testsuite/ada/acats/tests/cxb/cxb30132.am new file mode 100644 index 000000000..4cff400b8 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cxb/cxb30132.am @@ -0,0 +1,205 @@ +-- CXB30132.AM +-- +-- 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).

Two C language +-- functions are specified in files CXB30130.C and CXB30131.C. +-- These two functions are imported to this test program, using two +-- calls to Pragma Import. Each function is then called in this test, +-- and the results of the call are verified. +-- +-- This test assumes that the following characters are all included +-- in the implementation defined type Interfaces.C.char: +-- ' ', 'a'..'z', and 'A'..'Z'. +-- +-- APPLICABILITY CRITERIA: +-- This test is applicable to all implementations that provide +-- packages Interfaces.C and Interfaces.C.Strings. If an +-- implementation provides packages Interfaces.C and +-- Interfaces.C.Strings, this test must compile, execute, and +-- report "PASSED". +-- +-- SPECIAL REQUIREMENTS: +-- The files CXB30130.C and CXB30131.C must be compiled with a C +-- compiler. Implementation dialects of C may require alteration of +-- the C program syntax (see individual C files). +-- +-- Note that the compiled C code must be bound with the compiled Ada +-- code to create an executable image. An implementation must provide +-- the necessary commands to accomplish this. +-- +-- Note that the C code included in CXB30130.C and CXB30131.C conforms +-- to ANSI-C. Modifications to these files may be required for other +-- C compilers. An implementation must provide the necessary +-- modifications to satisfy the function requirements. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- CXB30130.C +-- CXB30131.C +-- CXB30132.AM +-- +-- +-- CHANGE HISTORY: +-- 13 Oct 95 SAIC Initial prerelease version. +-- 13 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. +-- 26 Oct 96 SAIC Incorporated reviewer comments. +-- +--! + +with Report; +with Impdef; +with Interfaces.C; -- N/A => ERROR +with Interfaces.C.Strings; -- N/A => ERROR + +procedure CXB30132 is +begin + + Report.Test ("CXB3013", "Check that user-defined C functions can " & + "be imported into an Ada program"); + + Test_Block: + declare + + package IC renames Interfaces.C; + package ICS renames Interfaces.C.Strings; + + use type IC.char_array; + use type IC.int; + use type IC.short; + use type IC.C_float; + use type IC.double; + + type Short_Ptr is access all IC.short; + type Float_Ptr is access all IC.C_float; + type Double_Ptr is access all IC.double; + subtype Char_Array_Type is IC.char_array(0..20); + + TC_Default_int : IC.int := 49; + TC_Default_short : IC.short := 3; + TC_Default_float : IC.C_float := 50.0; + TC_Default_double : IC.double := 1209.0; + + An_Int_Value : IC.int := TC_Default_int; + A_Short_Value : aliased IC.short := TC_Default_short; + A_Float_Value : aliased IC.C_float := TC_Default_float; + A_Double_Value : aliased IC.double := TC_Default_double; + + A_Short_Int_Pointer : Short_Ptr := A_Short_Value'access; + A_Float_Pointer : Float_Ptr := A_Float_Value'access; + A_Double_Pointer : Double_Ptr := A_Double_Value'access; + + Char_Array_1 : Char_Array_Type; + Char_Array_2 : Char_Array_Type; + Char_Pointer : ICS.chars_ptr; + + TC_Char_Array : constant Char_Array_Type := + "Look before you leap" & IC.nul; + TC_Return_int : IC.int := 0; + + -- The Square_It function returns the square of the value The_Int + -- through the function name, and returns the square of the other + -- parameters through the parameter list (the last three parameters + -- are access values). + + function Square_It (The_Int : in IC.int; + The_Short : in Short_Ptr; + The_Float : in Float_Ptr; + The_Double : in Double_Ptr) return IC.int; + + -- The Combine_Strings function returns the result of the catenation + -- of the two string parameters through the function name. + + function Combine_Strings (First_Part : in IC.char_array; + Second_Part : in IC.char_array) + return ICS.chars_ptr; + + + -- Use the user-defined C function square_it as a completion to the + -- function specification above. + + pragma Import (Convention => C, + Entity => Square_It, + External_Name => Impdef.CXB30130_External_Name); + + -- Use the user-defined C function combine_two_strings as a completion + -- to the function specification above. + + pragma Import (C, Combine_Strings, Impdef.CXB30131_External_Name); + + + begin + + -- Check that the imported version of C function CXB30130 produces + -- the correct results. + + TC_Return_int := Square_It (The_Int => An_Int_Value, + The_Short => A_Short_Int_Pointer, + The_Float => A_Float_Pointer, + The_Double => A_Double_Pointer); + + -- Compare the results with the expected results.
