In gcov/g++ 3.3, if I compile with "g++ test.cc -ftest-coverage -fprofile-arcs",
and then run "gcov test.cc", "test.cc.gcov" contains 2 lines of preamble, and
then 1 line for each line of test.cc
in gcov/g++ 4.1, Extra lines are added. I can't seem to disable these, and I'm
not positive why they are there. In particular they confuse programs which use
the output of "gcov"..
Specific example:
Given temp.cc:
template <typename T>
int
foo(T t)
{
if(t==1)
return 1;
else
return 0;
}
int main(void)
{ foo(1); }
Then "g++-3.3 temp.cc -ftest-coverage -fprofile-arcs; ./a.out ; gcov-3.3
temp.cc" gives
-: 0:Source:temp.cc
-: 0:Object:temp.bb
-: 1:template <typename T>
-: 2:int
-: 3:foo(T t)
-: 4:{
1: 5: if(t==1)
1: 6: return 1;
-: 7: else
#####: 8: return 0;
-: 9:}
-: 10:
-: 11:
-: 12:int main(void)
2: 13:{ foo(1); }
Whereas "g++-cvs temp.cc -ftest-coverage -fprofile-arcs ; ./a.out ; gcov-cvs
temp.cc" gives
-: 0:Source:temp.cc
-: 0:Graph:temp.gcno
-: 0:Data:temp.gcda
-: 0:Runs:1
-: 0:Programs:1
-: 1:template <typename T>
-: 2:int
function _Z3fooIiEiT_ called 1 returned 100% blocks executed 75%
1: 3:foo(T t)
-: 4:{
1: 5: if(t==1)
1: 6: return 1;
-: 7: else
#####: 8: return 0;
-: 9:}
-: 10:
-: 11:
function main called 1 returned 100% blocks executed 100%
1: 12:int main(void)
1: 13:{ foo(1); }
Is it possible to turn this off? Is it a regression?
