Enable ThinLTO for dex2oat
This helps reducing binary size as well as improve performance of
dex2oat.
On Marlin (lower clocked cores)
With PGO
dex2oat binary + libraries size:
- no-lto: 9.90MB
- thin-lto: 9.81MB
dex2oat run time for top 25 apps (with speed filter):
Average case: -2.83%
Best case : -4.65%
Worst case : 0.25%, likely noise
Without PGO
dex2oat binary + libraries size:
- no-lto: 9.67MB
- thin-lto: 9.60MB
dex2oat run time for top 25 apps (with speed filter):
Average case : -0.96%
Best case : -2.30%
Worst case : 0.52%, likely noise
Test: Benchmark on Marlin (low-clock cores)
