Bug ID: 82633
Summary: gcov does not handle removed functions
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
For following test-case:
class MyClass2
{
public:
void iterate() { a = 5; }
int a;
};
int main()
{
MyClass2 a;
return 0;
}
We wrongly don't identify that function iterate has no executions:
-: 1:class MyClass2
-: 2:{
-: 3: public:
-: 4: void iterate() { a = 5; }
-: 5:
-: 6: int a;
-: 7:};
-: 8:
1: 9:int main()
-: 10:{
-: 11: MyClass2 a;
1: 12: return 0;
-: 13:}
It's caused by fact that it's removed from cgraph:
removed.cpp.000i.cgraph:Removing unused symbols: void MyClass2::iterate()
