294 | -- da Generate messages tracking semantic analyzer progress. A message | |
295 | -- is output showing each node as it gets analyzed, expanded, | |
296 | -- resolved, or evaluated. This option is useful for finding out | |
297 | -- exactly where a bomb during semantic analysis is occurring. | |
298 | ||
299 | -- db In Exp_Dbug, certain type names are encoded to include debugging | |
300 | -- information. This debug switch causes lines to be output showing | |
301 | -- the encodings used. | |
302 | ||
303 | -- dc List names of units as they are compiled. One line of output will | |
304 | -- be generated at the start of compiling each unit (package or | |
305 | -- subprogram). | |
306 | ||
307 | -- dd Dynamic allocation of tables messages generated. Each time a | |
308 | -- table is reallocated, a line is output indicating the expansion. | |
309 | ||
70482933 RK |
310 | -- de List the entity table |
311 | ||
312 | -- df Full tree/source print (includes withed units). Normally the tree | |
313 | -- output (dt) or recreated source output (dg,do,ds) includes only | |
314 | -- the main unit. If df is set, then the output in either case | |
315 | -- includes all compiled units (see also dg,do,ds,dt). Note that to | |
d8d7e809 | 316 | -- be effective, this switch must be used in combination with one or |
70482933 RK |
317 | -- more of dt, dg, do or ds. |
318 | ||
70482933 RK |
319 | -- dg Print the source recreated from the generated tree. In the case |
320 | -- where the tree has been rewritten this output includes only the | |
321 | -- generated code, not the original code (see also df,do,ds,dz). | |
322 | -- This flag differs from -gnatG in that the output also includes | |
323 | -- non-source generated null statements, and freeze nodes, which | |
324 | -- are normally omitted in -gnatG mode. | |
325 | ||
70482933 RK |
326 | -- dh Generates a table at the end of a compilation showing how the hash |
327 | -- table chains built by the Namet package are loaded. This is useful | |
328 | -- in ensuring that the hashing algorithm (in Namet.Hash) is working | |
329 | -- effectively with typical sets of program identifiers. | |
330 | ||
70482933 RK |
331 | -- di Generate messages for visibility linking/delinking |
332 | ||
333 | -- dj Suppress "junk null check" for access parameters. This flag permits | |
334 | -- Ada programs to pass null parameters to access parameters, and to | |
335 | -- explicitly check such access values against the null literal. | |
336 | -- Neither of these is valid Ada, but both were allowed in versions of | |
337 | -- GNAT before 3.10, so this switch can ease the transition process. | |
338 | ||
70482933 RK |
339 | -- dk Immediate kill on abort. Normally on an abort (i.e. a call to |
340 | -- Comperr.Compiler_Abort), the GNATBUG message is not given if | |
341 | -- there is a previous error. This debug switch bypasses this test | |
342 | -- and gives the message unconditionally (useful for debugging). | |
343 | ||
70482933 RK |
344 | -- dl Generate unit load trace messages. A line of traceback output is |
345 | -- generated each time a request is made to the library manager to | |
346 | -- load a new unit. | |
347 | ||
c1025b4e AC |
348 | -- dm Prevent special frontend inlining in GNATprove mode. In some cases, |
349 | -- some subprogram calls are inlined in GNATprove mode in order to | |
350 | -- facilitate formal verification. This debug switch prevents that | |
351 | -- inlining to happen. | |
352 | ||
70482933 RK |
353 | -- dn Generate messages for node/list allocation. Each time a node or |
354 | -- list header is allocated, a line of output is generated. Certain | |
355 | -- other basic tree operations also cause a line of output to be | |
356 | -- generated. This option is useful in seeing where the parser is | |
5e39baa6 | 357 | -- blowing up. |
70482933 | 358 | |
70482933 RK |
359 | -- do Print the source recreated from the generated tree. In the case |
360 | -- where the tree has been rewritten, this output includes only the | |
361 | -- original code, not the generated code (see also df,dg,ds,dz). | |
362 | ||
363 | -- dp Generate messages for parser scope stack push/pops. A line of | |
364 | -- output by the parser each time the parser scope stack is either | |
365 | -- pushed or popped. Useful in debugging situations where the | |
366 | -- parser scope stack ends up incorrectly synchronized | |
367 | ||
07fc65c4 GB |
368 | -- dq In layout version 1.38, 2002/01/12, a circuit was implemented |
369 | -- to give decent default alignment to short records that had no | |
370 | -- specific alignment set. This debug option restores the previous | |
371 | -- behavior of giving such records poor alignments, typically 1. | |
372 | -- This may be useful in dealing with transition. | |
373 | ||
70482933 RK |
374 | -- dr Generate parser resynchronization messages. Normally the parser |
375 | -- resynchronizes quietly. With this debug option, two messages | |
376 | -- are generated, one when the parser starts a resynchronization | |
377 | -- skip, and another when it resumes parsing. Useful in debugging | |
378 | -- inadequate error recovery situations. | |
379 | ||
380 | -- ds Print the source recreated from the generated tree. In the case | |
381 | -- where the tree has been rewritten this output includes both the | |
382 | -- generated code and the original code with the generated code | |
383 | -- being enlosed in curly brackets (see also df,do,ds,dz) | |
384 | ||
385 | -- dt Print full tree. The generated tree is output (see also df,dy) | |
386 | ||
387 | -- du Uncheck categorization pragmas. This debug switch causes the | |
cbc61965 AC |
388 | -- elaboration control pragmas (Pure, Preelaborate, etc.) and the |
389 | -- categorization pragmas (Shared_Passive, Remote_Types, etc.) to be | |
390 | -- ignored, so that normal checks are not made (this is particularly | |
391 | -- useful for adding temporary debugging code to units that have | |
392 | -- pragmas that are inconsistent with the debugging code added). | |
70482933 | 393 | |
fbf5a39b AC |
394 | -- dv Output trace of overload resolution. Outputs messages for |
395 | -- overload attempts that involve cascaded errors, or where | |
