Bug ID: 60833
Summary: Inheritance via typedef skips the typedef
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: dblaikie at gmail dot com
struct base {
};
typedef base tbase;
struct derived: tbase {
} x;
GCC doesn't emit the typedef of 'tbase' and instead describes 'derived' as
directly deriving from 'base'.

GCC doesn't emit the typedef for tbase because it is unused. It will emit the typedef for tbase when it is used for a variable like tbase y. But even then it will optimize out the typedef from the inherentence tree and make the DW_TAG_inherentence tag DW_AT_type attribute of the derived struct DIE point directly to the struct base type DIE. ^ permalink raw reply [flat|nested] 3+ messages in thread

(though, admittedly, I don't know that this extra debug info provides much value at the moment - I think GDB mostly looks straight through typedefs) ^ permalink raw reply [flat|nested] 3+ messages in thread
