=================================================================== |
| 16 |
GCCs options -fprofile-generate and -fprofile-use are used for |
| 17 |
profile guided optimization. It depends on the ability to locate |
| 18 |
the profile data files (.gcda) after running the executable with |
| 19 |
the training data. However, ccache prevents the compiler from |
| 20 |
finding the correct profile data file. Therefore the following |
| 21 |
patch disables the caching when one of the |
| 22 |
-fprofile-generate |
| 23 |
-fprofile-use |
| 24 |
-fprofile-arcs |
| 25 |
flags is found. |
