Bug ID: 101015
Summary: Poor diagnostic for deprecated alias-declaration
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
struct A {
typedef int good [[deprecated]];
using bad [[deprecated]] = int;
};
A::good i = 0;
A::bad j = 0;
This prints:
depr.C:6:9: warning: 'A::good' is deprecated [-Wdeprecated-declarations]
6 | A::good i = 0;
| ^
depr.C:2:15: note: declared here
2 | typedef int good [[deprecated]];
| ^~~~
depr.C:7:8: warning: 'using bad = int' is deprecated
[-Wdeprecated-declarations]
7 | A::bad j = 0;
| ^
depr.C:3:9: note: declared here
3 | using bad [[deprecated]] = int;
| ^~~
When it is good it is very very good, but when it is bad it is horrid.
The second warning should print 'A::bad' not 'using bad = int'.
