As I said before you have to use right version of the gcov tool for the 
compiler (e.g. ntomips-gcov-3.3.5 for gcc 3.3.5).

Here is a simple example of getting cumulative results:

# cat simple.c
#include <stdio.h>

int main(int argc, char *argv[]) {
  if (argc > 1) {
   printf("foo\n");
  } else {
   printf("bar\n");
  }
}

# qcc -V3.3.5,gcc_ntomipsbe -ftest-coverage -fprofile-arcs simple.c -o 
simple

On the target doing multiple runs:

# ./simple
bar

# ./simple 1
foo

# ./simple 2
foo

# ./simple 3
foo

On the host side:

# ntomips-gcov-3.3.5 -f simple.da
100.00% of 4 lines executed in function main
100.00% of 4 lines executed in file simple.c
Creating simple.c.gcov.
# cat simple.c.gcov
         -:    0:Source:simple.c
         -:    0:Object:simple.bb
         -:    1:#include <stdio.h>
         -:    2:
         4:    3:int main(int argc, char *argv[]) {
         4:    4: if (argc > 1) {
         3:    5:  printf("foo\n");
         -:    6: } else {
         1:    7:  printf("bar\n");
         -:    8: }
         -:    9:}
         -:   10:

As you can see from the generated gcov file code coverage data is 
collected from multiple runs.
