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/gnat.dg/unc_memops.adb | 63 ++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 gcc/testsuite/gnat.dg/unc_memops.adb (limited to 'gcc/testsuite/gnat.dg/unc_memops.adb') diff --git a/gcc/testsuite/gnat.dg/unc_memops.adb b/gcc/testsuite/gnat.dg/unc_memops.adb new file mode 100644 index 000000000..356fc0100 --- /dev/null +++ b/gcc/testsuite/gnat.dg/unc_memops.adb @@ -0,0 +1,63 @@ + +package body Unc_Memops is + + use type System.Address; + + type Addr_Array_T is array (1 .. 20) of Addr_T; + + type Addr_Stack_T is record + Store : Addr_Array_T; + Size : Integer := 0; + end record; + + procedure Push (Addr : Addr_T; As : access addr_stack_t) is + begin + As.Size := As.Size + 1; + As.Store (As.Size) := Addr; + end; + + function Pop (As : access Addr_Stack_T) return Addr_T is + Addr : Addr_T := As.Store (As.Size); + begin + As.Size := As.Size - 1; + return Addr; + end; + + -- + + Addr_Stack : aliased Addr_Stack_T; + Symetry_Expected : Boolean := False; + + procedure Expect_Symetry (Status : Boolean) is + begin + Symetry_Expected := Status; + end; + + function Alloc (Size : size_t) return Addr_T is + function malloc (Size : Size_T) return Addr_T; + pragma Import (C, Malloc, "malloc"); + + Ptr : Addr_T := malloc (Size); + begin + if Symetry_Expected then + Push (Ptr, Addr_Stack'Access); + end if; + return Ptr; + end; + + procedure Free (Ptr : addr_t) is + begin + if Symetry_Expected + and then Ptr /= Pop (Addr_Stack'Access) + then + raise Program_Error; + end if; + end; + + function Realloc (Ptr : addr_t; Size : size_t) return Addr_T is + begin + raise Program_Error; + return System.Null_Address; + end; + +end; -- cgit v1.2.3
