            Bug ID: 96010
           Summary: std::make_tuple called over multiple lines reports
                    lines as "not run"
           Product: gcc
           Version: 10.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: loximann at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

I hope that the gcov file is self-explanatory:

        -:    0:Source:coverage_test.cpp
        -:    0:Graph:coverage_test.gcno
        -:    0:Data:coverage_test.gcda
        -:    0:Runs:1
        -:    1:#include <tuple>
        -:    2:
        1:    3:auto g(int, int, int)
        -:    4:{
        1:    5:    return 0;
        -:    6:}
        -:    7:
        1:    8:auto f()
        -:    9:{
        1:   10:    return g(1,
        -:   11:            2,
        1:   12:            3);
        -:   13:}
        -:   14:
        1:   15:auto h()
        -:   16:{
    #####:   17:    return std::make_tuple(1,
    #####:   18:            2,
        2:   19:            3);
        -:   20:}
        -:   21:
        1:   22:int main(int argc, char *argv[]) {
        1:   23:    f();
        1:   24:    h();
        1:   25:  return 0;
        -:   26:}

I do not know if this happens for other functions, but with that simple dummy
function the lines were annotated correctly.

Confirmed. It likely happens also for similar cases, note that it's not easy to
handle correctly these multiline statements.

On a side note: are these bug reports I am sending useful in their current
form? Anything else that I can do to help? (Other than actually fixing them,
because I feel awfully unqualified to even start looking...)

You're doing well, but as said, we have quite some GCOV issues that are quite
similar to this one. And it seems quite low priority to me for now.

You can inspire about what bugs we have here:
https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=__open__&component=gcov-profile&list_id=273005&product=gcc

these starting with "[GCOV]".
