3.23. pragma Machine_Attribute ...

Syntax
pragma Machine_Attribute (
  [Attribute_Name =>] string_EXPRESSION,
  [Entity         =>] LOCAL_NAME);

Machine dependent attributes can be specified for types and/or declarations. Currently only subprogram entities are supported. This pragma is semantically equivalent to __attribute__(( string_expression)) in GNU C, where string_expression> is recognized by the GNU C macros VALID_MACHINE_TYPE_ATTRIBUTE and VALID_MACHINE_DECL_ATTRIBUTE which are defined in the configuration header file tm.h for each machine. See the GCC manual for further information.
