-- resolved, or evaluated. This option is useful for finding out
-- exactly where a bomb during semantic analysis is occurring.
+ -- dA Normally the output from -gnatR excludes private types and all
+ -- internal entities. This debug flag causes representation info
+ -- for these entities to be output as well.
+
-- db In Exp_Dbug, certain type names are encoded to include debugging
-- information. This debug switch causes lines to be output showing
-- the encodings used.
-- non-source generated null statements, and freeze nodes, which
-- are normally omitted in -gnatG mode.
- -- dG Print trace information showing calls to Create_Debug_Source and
- -- Write_Debug_Line. Used for debugging -gnatD operation problems.
-
-- dh Generates a table at the end of a compilation showing how the hash
-- table chains built by the Namet package are loaded. This is useful
-- in ensuring that the hashing algorithm (in Namet.Hash) is working
-- attempting to generate code with this flag set may blow up.
-- The flag also forces the use of 64-bits for Long_Integer.
- -- dM Generate modified ALI output. Several ALI extensions are being
- -- developed for version 3.15w, and this switch is used to enable
- -- these extensions. This switch will disappear when this work is
- -- completed.
-
-- dn Generate messages for node/list allocation. Each time a node or
-- list header is allocated, a line of output is generated. Certain
-- other basic tree operations also cause a line of output to be
-- pushed or popped. Useful in debugging situations where the
-- parser scope stack ends up incorrectly synchronized
+ -- dq In layout version 1.38, 2002/01/12, a circuit was implemented
+ -- to give decent default alignment to short records that had no
+ -- specific alignment set. This debug option restores the previous
+ -- behavior of giving such records poor alignments, typically 1.
+ -- This may be useful in dealing with transition.
+
-- dr Generate parser resynchronization messages. Normally the parser
-- resynchronizes quietly. With this debug option, two messages
-- are generated, one when the parser starts a resynchronization
-- the algorithm used to determine a correct order of elaboration. This
-- is useful in diagnosing any problems in its behavior.
- -- dr List restrictions which have not been specified, but could have
- -- been without causing bind errors.
-
-- du List unit name and file name for each unit as it is read in
