            Bug ID: 102746
           Summary: gcov returns 0 un erroneuos incovation
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: chipitsine at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

repro steps:

several source files (for example, two)

main.c:

void hello(void);

void main(void){
 hello();
}

hello.c:

#include <stdio.h>

void hello(void) {
   printf("hello"); 
}


..................

build with coverage (using master branch gcc)

gcc --coverage -o hello main.c hello.c

....................

execute

./hello



executing "gcov" in erroneous way 

gcov "hello-hello.gcda  hello-main.gcda"
hello-hello.gcda  hello-main.gcno:cannot open notes file
hello-hello.gcda  hello-main.gcda:cannot open data file, assuming not executed
No executable lines

however, exit status is "0"

$ echo $?
0
$



it is hard to identify error situation when exit status is "0". I beleive it
should be "1" under such circumstances
