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