-- This unit contains the routines used to handle setting of warning options
package Warnsw is
-------------------
-- Warning Flags --
-------------------
-- These flags are activated or deactivated by -gnatw switches and control
-- whether warnings of a given class will be generated or not.
-- Note: most of these flags are still in opt, but the plan is to move them
-- here as time goes by.
Warn_On_Record_Holes : Boolean := False;
-- Warn when explicit record component clauses leave uncovered holes (gaps)
-- in a record layout. Off by default, set by -gnatw.h (but not -gnatwa).
Warn_On_Overridden_Size : Boolean := False;
-- Warn when explicit record component clause or array component_size
-- clause specifies a size that overrides a size for the typen which was
-- set with an explicit size clause. Off by default, set by -gnatw.s (but
-- not -gnatwa).
-----------------
-- Subprograms --
-----------------
function Set_Warning_Switch (C : Character) return Boolean;
-- This function sets the warning switch or switches corresponding to the
-- given character. It is used to process a -gnatw switch on the command
-- line, or a character in a string literal in pragma Warnings. Returns
-- True for valid warning character C, False for invalid character.
function Set_Dot_Warning_Switch (C : Character) return Boolean;
-- This function sets the warning switch or switches corresponding to the
-- given character preceded by a dot. Used to process a -gnatw. switch on
-- the command line or .C in a string literal in pragma Warnings. Returns
-- True for valid warning character C, False for invalid character.
procedure Set_GNAT_Mode_Warnings;
-- This is called in -gnatg mode to set the warnings for gnat mode. It is
-- also used to set the proper warning statuses for -gnatw.g. Note that
-- this set of warnings is disjoint from -gnatwa, it enables warnings that
-- are not included in -gnatwa, and it disables warnings that are included
-- in -gnatwa (such as Warn_On_Implementation_Units, which we clearly want
-- to be False for units built with -gnatg).
