2.185 Pragma Universal_Aliasing

Syntax:

pragma Universal_Aliasing [([Entity =>] type_LOCAL_NAME)];

type_LOCAL_NAME must refer to a type declaration in the current declarative part. The effect is to inhibit strict type-based aliasing optimization for the given type. In other words, the effect is as though access types designating this type were subject to pragma No_Strict_Aliasing. For a detailed description of the strict aliasing optimization, and the situations in which it must be suppressed, see the section on Optimization and Strict Aliasing in the GNAT User’s Guide.
