| 10 # In the PGO (Profile-Guided Optimization) build flow, we need to build the |
| 11 # target binary multiple times. To implement this flow with gyp, here we |
| 12 # define multiple 'executable' targets, each of which represents one build |
| 13 # particular build/profile stage. On tricky part to do this is that these |
| 14 # 'executable' targets should share the code itself so that profile data |
| 15 # can be reused among these 'executable' files. In other words, the only |
| 16 # differences among below 'executable' targets are: |
| 17 # 1) PGO (Profile-Guided Optimization) database, and |
| 18 # 2) linker options. |
| 19 # The following static library contains all the logic including entry point. |
| 20 # Basically we don't need to rebuild this target once we enter profiling |
| 21 # phase of PGO. |
