Squashed commit of the following: commit b11f60fd9b601caa10f8caec5c9f3a10c5082d68 Author: Jared Duke <jdduke@google.com> Date: Wed Feb 16 15:43:55 2022 -0800 Enable R8 code shrinking for system_server on Pixel Opt in to whole-program Java optimizations via R8 for Pixel devices. This can be explicitly disabled during builds via `SYSTEM_OPTIMIZE_JAVA=false m`. Note that this change only enables code shrinking for system_server, and should not impact stack traces. Additional R8 optimizations will be enabled after broader improvements to retracing infrastructure. See go/aperf-system-r8-faq for additional details and guidance. Also note that R8 shrinking optimizations are implicitly disabled in ENG builds. Enabling for non-Pixel devices will proceed in stages as we flesh out infrastructure and validate with test populations. Results: services.jar (20MB -> 17MB) Bug: 210510433 Test: m + atest FrameworksServicesTests + manual testing on Raven Change-Id: I13c0674105aa2cab7722f52344486e86e3bde26b commit ecc5901ee57253edb0fdde5d5099c4e1078f7b6f Author: Jared Duke <jdduke@google.com> Date: Tue Jan 4 15:21:39 2022 -0800 Enable SystemUI R8 optimizations for Pixel Opt in to whole-program Java optimizations via R8 for Pixel devices. This can be explicitly disabled during builds via `SYSTEMUI_OPTIMIZE_JAVA=false m`. Note that this change does introduce changes to stack traces that may require retracing for fully accurate debugging and diagonstics. See go/aperf-system-r8-faq for additional details and guidance. Also note that optimizations are implicitly disabled in ENG builds. Enabling for non-Pixel devices will proceed in stages as we flesh out infrastructure and validate with test populations.

LineageOS =========== Getting started --------------- Please see the [LineageOS Wiki](https://wiki.lineageos.org/) for building instructions, by device. Submitting patches ------------------ Patches are always welcome! Please submit your patches via LineageOS Gerrit! Simply follow our guide on [how to submit patches](https://wiki.lineageos.org/submitting-patch-howto.html). To view the status of your and others' patches, visit [LineageOS Gerrit Code Review](https://review.lineageos.org/). Buildbot -------- All supported devices are built weekly and periodically as changes are committed to ensure the source trees remain buildable. You can view the current build statuses at [LineageOS Buildkite](https://buildkite.com/lineageos). Builds produced weekly by the buildbot can be downloaded from [LineageOS downloads](https://download.lineageos.org/).
