4252 – cc1: Invalid option `-fdump-translation-unit' (original) (raw)

| The command line options -fdump-translation-unit -fdump-class-hierarchy don't seem to work. However they are documented in both the Info and man pages. Also, said documentation alludes to -fdump-tree, but -fdump-tree neither works nor seems to be documented.

That patch doesn't apply cleanly against my currently checked out tree, and even if I manually fix one of the two parts, the second doesn't seem to exist. To make sure that I don't botch anything with my manual adjustments, would you mind updating your CVS tree and adjusting the patch? (If you have CVS write access, the updated patch is approved. If you have not, we probably should arrange for full CVS write access -- see http://gcc.gnu.org/cvswrite.html for details.) Thanks, Gerald -- Gerald "Jerry" pfeifer@dbai.tuwien.ac.at http://www.dbai.tuwien.ac.at/~pfeifer/ Comment 6 Eric Weddington 2003-05-23 23:37:22 UTC Everything up to Comment #4 is resolved, and then in Comment #4 Craig Rodrigues states: "The -fdump-tree option does not seem to exist." This is in reference to the description of -fdump-class-hierarchy-options in Debugging Options in the manual <http://gcc.gnu.org/onlinedocs/gcc-3.3/gcc/Debugging-Options.html#Debugging%20Op tions> where the description states: -fdump-class-hierarchy-options (C++ only) Dump a representation of each class's hierarchy and virtual function table layout to a file. The file name is made by appending .class to the source file name. If the -options form is used, options controls the details of the dump as described for the -fdump-tree options. So, in context, the description is not referring to a non-existent -fdump-tree switch. It is referring to the -fdump-tree-switch-options description right below it in the manual. Craig's patch in Comment #4 is probably not needed, then. Unless further clarification in the manual is deemed necessary. If it is not necessary, then this bug can probably be set to RESOLVED. Eric Weddington Comment 7 Dara Hazeghi 2003-05-27 05:00:02 UTC Hello, this problem is still present in the gcc 3.3 and mainline docs (see http://gcc.gnu.org/onlinedocs/ gcc/Debugging-Options.html#Debugging%20Options for instance) . Would some kind soul like to make a patch for this? Otherwise it looks like it'll get forgotten again... Dara Comment 8 Drea Pinski 2003-05-27 14:34:24 UTC See Dara's comment, we really need a document component and I mark this as something that should be done by 3.3.1 because it seems like the document is still wrong and it is a regression from when the documentation was changed. Comment 9 Bob Abeles 2003-06-17 18:41:10 UTC I ran into this bug (cc1: Invalid option '-fdump-translation-unit') on the 3.4 mainline, and then found this problem report in Bugzilla. Reviewing the patch "2001-06-05 Nathan Sidwell", I see that Nathan did not remove the -fdump-translation-unit command-line flag; instead, he changed the way that the '-fdump'-prefixed options were handled, removing an obsolete internal flag named flag_dump_translation_unit. A subsequent misreading of this comment has spawned the confusion over whether the command-line flag should be removed from the documentation. My conclusion is that the documentation is correct, and that there is a genuine bug that prevents the -fdump-translation-unit command-line flag from working. I have a proposed patch to the mainline which fixes this bug; I will attach it shortly. Comment 11 Neil Booth 2003-06-18 06:01:18 UTC Should be fixed by Robert Abeles' patch. | | |
