使用gcc 6.2.1中的ADA中使用属性scalar_storage_order

发布于 2025-01-31 01:58:12 字数 559 浏览 2 评论 0原文

我目前正在尝试找到一个解决方案，以控制ADA中记录中元素的存储顺序。

我正在使用GCC 6.2.1，该gcc 6.2.1无法识别scalar_storage_order属性（即使在GCC 6.2 GNAT参考手册中清楚地引用了属性）。

type Rec is record

      Data1 : T_Data;
      Data2 : T_Data;

   end record;

for Rec use
      record

         Data1      at 0 range 0 .. 15;
         Data2      at 0 range 0 .. 15;

      end record;

for Rec'Bit_Order use System.High_Order_First;
for Rec'Scalar_Storage_Order use System.High_Order_First;

error: unrecognized attribute "Scalar_Storage_Order"

我可以用来实现自己的目标吗？

原文

I'm currently trying to find a solution to control the storage order for elements within a record in ADA.

I'm using gcc 6.2.1 which doesnt recognize the Scalar_Storage_Order attribute ( even though the attribute is clearly referenced in the gcc 6.2 GNAT reference manual).

type Rec is record

      Data1 : T_Data;
      Data2 : T_Data;

   end record;

for Rec use
      record

         Data1      at 0 range 0 .. 15;
         Data2      at 0 range 0 .. 15;

      end record;

for Rec'Bit_Order use System.High_Order_First;
for Rec'Scalar_Storage_Order use System.High_Order_First;

error: unrecognized attribute "Scalar_Storage_Order"

Is there an alternative that I can use to achieve my goal?
