| 11 | |
| Dmitri Gribenko | c9e206f | 2012-11-29 19:10:21 +0000 | [diff] [blame] | 12 | The experimental :program:`llvm-cov` tool reads in description file generated |
| 13 | by compiler and coverage data file generated by instrumented program. This |
| 14 | program assumes that the description and data file uses same format as gcov |
| 15 | files. |
