Update PGO profiles for dex2oat The profiles are from build 8415607 (TP1A.220407.001). Bug: 208758501 Test: Build (TH) Change-Id: Id4063e4d9f0d819d5c7b190a991939aa6885bcb1
For the latest version of this doc, please make sure to visit: Android PGO Profiles
First, you need to install python-pip
, as well as 2 packages from it.
$ sudo apt-get install python-pip $ sudo pip install --upgrade google-api-python-client $ sudo pip install --upgrade oauth2client
We only update profiles in the Android release branch, so this script should be run directly from that location. The following is a sample command line for updating the PGO profiles:
$ python toolchain/pgo-profiles/scripts/update_profiles.py -b <BUG_NUMBER> --add-do-not-merge <BUILD_ID> ALL --profdata-suffix <YYYY-MM-DD> $ repo upload --cbr toolchain/pgo-profiles/ # Each separate profile will be uploaded as a single patch, so that it can get appropriate reviews.
Note that you need to change that command to supply 3 pieces of information:
BUG_NUMBER
: The buganizer bug number that should be part of the commit message. For Android R, that bug number is 150254950.BUILD_ID
: The build id from which to extract the PGO profiles. You should check go/ab for the given release branch.YYYY-MM-DD
: The date of the build that the profiles come from (to keep it easier to check for stale profiles).PGO-related questions should be sent to the Android LLVM team's public list: android-llvm@googlegroups.com
