* [Bug debug/45124] New: No DW_AT_accessibility for public DIEs in DW_TAG_class_type @ 2010-07-29 8:32 jakub at gcc dot gnu dot org 2010-07-29 8:55 ` [Bug debug/45124] " jakub at gcc dot gnu dot org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: jakub at gcc dot gnu dot org @ 2010-07-29 8:32 UTC (permalink / raw) To: gcc-bugs Dwarf 3 and 4 state that if DW_AT_accessibility is missing, the default is DW_ACCESS_private in DW_TAG_class_type and DW_ACCESS_public otherwise. Unfortunately dwarf2out.c assumes the default is DW_ACCESS_public always. Not sure if GDB (or other dwarf consumers) makes the same assumption. If not, then we can add DW_ACCESS_public DW_AT_accessibility in DW_TAG_class_type for everything that didn't have it till now and drop DW_ACCESS_private accessibility, if yes, then I'm afraid all we can do for the time being is just add DW_ACCESS_public accessibility and keep DW_ACCESS_private accessibility too. -- Summary: No DW_AT_accessibility for public DIEs in DW_TAG_class_type Product: gcc Version: 4.5.0 Status: UNCONFIRMED Keywords: wrong-debug Severity: normal Priority: P3 Component: debug AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45124 ^ permalink raw reply [flat|nested] 5+ messages in thread

The default accessibility for members is public, the default accessibility for inheritance is private. */ if (die->tag != DW_TAG_inheritance) new_field->accessibility = DW_ACCESS_public; else new_field->accessibility = DW_ACCESS_private; i.e. it seems to match what GCC (wrongly) does. I'm afraid we need to live with some extra DW_AT_accessibility attributes for compatibility. -- jakub at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |jakub at gcc dot gnu dot org |dot org | Status|UNCONFIRMED |ASSIGNED Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2010-07-29 08:55:14 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45124 ^ permalink raw reply [flat|nested] 5+ messages in thread
