| 317 | Reduce the number of unit tests run for the PGO generation task. This |
| 318 | speeds up the task by a factor of about 15x. Running the full unit test |
| 319 | suite is slow. This change may result in a slightly less optimized build |
| 320 | since not as many code branches will be executed. If you are willing to |
| 321 | wait for the much slower build, the old behavior can be restored using |
| 322 | './configure [..] PROFILE_TASK="-m test --pgo-extended"'. We make no |
| 323 | guarantees as to which PGO task set produces a faster build. Users who care |
| 324 | should run their own relevant benchmarks as results can depend on the |
| 325 | environment, workload, and compiler tool chain. |
