-GHDL coding style
-*****************
-
-Ada subset: use only a simple (VHDL like) subset of Ada: no tasking, no
-controlled types...  VHDL users should easily understand that subset.
-Allowed Ada93 features: the standard library, child packages.
-Use assertions.
-
-We try to follow the 'GNU Coding Standards' when possible: comments before
-declarations, two spaces at end of sentences, finish sentences with a dot.
-But: 3 spaces for indentation.
-
-No trailing spaces, not TAB (HT).
-
-Subprograms must have a comment before to describe it, like:
-   --  Analyze the concurrent statements of PARENT.
-   procedure Sem_Concurrent_Statement_Chain (Parent : Iir);
-The line before the comment must be a blank line (unless this is the first
-declaration).  Don't repeat the comment before the subprogram body.
-
-* For subprograms:
-1) Declare on one line when possible:
-   function Translate_Static_Aggregate (Aggr : Iir) return O_Cnode
-
-2) If not possible, put the return on the next line:
-   function Translate_Static_String (Str_Type : Iir; Str_Ident : Name_Id)
-                                    return O_Cnode
-
-3) If not possible, put parameters and return on the next line:
-   function Create_String_Literal_Var_Inner
-     (Str : Iir; Element_Type : Iir; Str_Type : O_Tnode) return Var_Type
-
-4) If not possible, return on the next line:
-   function Translate_Shortcut_Operator
-     (Imp : Iir_Implicit_Function_Declaration; Left, Right : Iir)
-     return O_Enode
-
-5) If not possible, one parameter per line, just after subprogram name:
-   procedure Translate_Static_Aggregate_1 (List : in out O_Array_Aggr_List;
-                                           Aggr : Iir;
-                                           Info : Iir;
-                                           El_Type : Iir)
-6) If not possible, add a return after subprogram name:
-   function Translate_Predefined_TF_Array_Element
-     (Op : Predefined_Boolean_Logical;
-      Left, Right : Iir;
-      Res_Type : Iir;
-      Loc : Iir)
-     return O_Enode
-
-7) If not possible, ask yourself what is wrong!  Shorten a name.
-
-* Rule for the 'is': one a new line only if the declarative part is not empty:
-   procedure Translate_Assign (Target : Mnode; Expr : Iir; Target_Type : Iir)
-   is
-      Val : O_Enode;
-   begin
-vs
-   function Translate_Static_Range_Dir (Expr : Iir) return O_Cnode is
-   begin
-
-If the parametere line is too long with the 'is', put in on a separate line:
-      procedure Predeclare_Scope_Type
-        (Scope : in out Var_Scope_Type; Name : O_Ident) is
-
-* Generic instantiation: put the generic actual part on a new line:
-   procedure Free is new Ada.Unchecked_Deallocation
-     (Action_List, Action_List_Acc);
-
-* For if/then statement:
-1) 'then' on the same line:
-      if Get_Expr_Staticness (Decl) = Locally then
-
-2) If not possible, 'then' is alone on its line aligned with the 'if':
-      if Expr = Null_Iir
-        or else Get_Kind (Expr) = Iir_Kind_Overflow_Literal
-      then
-
-3) For a multiline condition, 'or else' and 'and then' should start lines.
-
-* 'Local' variable declaration:
-Do not initialize variables, constants must be declared before variables:
-   is
-      N_Info : constant Iir := Get_Sub_Aggregate_Info (Info);
-      Assoc  : Iir;
-      Sub    : Iir;
-   begin
-If the initialization expression has a side effect (such as allocation), do
-not use a constant.
