| 17 | 2- Convert the profile to text encoding and check that they are both |
| 18 | identical. |

| 23 | 4- Merge the gcov and text encodings of the profile and check that the |
| 24 | counters have doubled. |
| 25 | RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov -o %t-gcov |
