s-stausa.ads (Stack_Analyzer): Remove First_Is_Topmost, redundant with Stack_Grows_Down in System.Parameters.
2007-12-06 Olivier Hainque <hainque@adacore.com>
* s-stausa.ads (Stack_Analyzer): Remove First_Is_Topmost, redundant
with Stack_Grows_Down in System.Parameters. Rename Array_Address into
Stack_Overlay_Address and document that we are using an internal
abstraction.
(Byte_Size, Unsigned_32_Size): Remove, now useless.
(Pattern_Type, Bytes_Per_Pattern): New subtype and constant, to be used
consistently throughout the various implementation pieces.
* s-stausa.adb (Stack_Slots): New type, abstraction for the stack
overlay we are using to fill the stack area with patterns.
(Top_Slot_Index_In, Bottom_Slot_Index_In): Operations on Stack_Slots.
(Push_Index_Step_For, Pop_Index_Step_For): Likewise.
(Fill_Stack, Compute_Result): Use the Stack_Slots abstraction.
