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