Bug ID: 109177
Summary: Call to C++ function marked unavailable gets diagnosed
twice
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: acoplan at gcc dot gnu.org
Target Milestone: ---
Reproducer:
$ cat t.cc
void f() __attribute__((unavailable));
void g() { f(); }
$ gcc/xgcc -B gcc -c t.cc
t.cc: In function ‘void g()’:
t.cc:2:13: error: ‘void f()’ is unavailable
2 | void g() { f(); }
| ~^~
t.cc:1:6: note: declared here
1 | void f() __attribute__((unavailable));
| ^
t.cc:2:13: error: ‘void f()’ is unavailable
2 | void g() { f(); }
| ~^~
t.cc:1:6: note: declared here
1 | void f() __attribute__((unavailable));
| ^
This only seems to happen in C++ mode, C diagnoses this once as expected.
