Bug ID: 42110
Summary: llvm-cov: unused methods of template classes are not
shown as uncovered
Product: new-bugs
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: dennis.fels...@sap.com
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org
$ cat x.cpp
template<typename T>
struct C
{
C(T x)
: v(x)
{
}
void foo(T x)
{
v = x;
}
T v;
};
int main()
{
C<int> c(5);
}
$ clang++ -fprofile-instr-generate -fcoverage-mapping x.cpp -o x
$ ./x
$ llvm-profdata merge -sparse default.profraw -o default.profdata
$ llvm-cov show ./x -instr-profile=default.profdata
1| |template<typename T>
2| |struct C
3| |{
4| | C(T x)
5| | : v(x)
6| 1| {
7| 1| }
8| |
9| | void foo(T x)
10| | {
11| | v = x;
12| | }
13| |
14| | T v;
15| |};
16| |
17| |int main()
18| 1|{
19| 1| C<int> c(5);
20| 1|}
I would expect foo to be considered uncovered, but since the method is inside
of a template class it is apparently not generated when it's also not used. If
the class is non-templated foo is shown correctly as being uncovered.
