We enabled PGO for Android ARMv7 in bug 632954 and for Fennec Nightlies in bug 1535364. PGO for ARM64 requires additional work.

Depends on: android-pgo-ARMv7

Type: defect → task

It sounds like bug 1545497 may take a while to be staffed, so in the meantime we can use the android-api-16 profile for aarch64 builds instead of moving both to using an android-x86 profile. This will get us PGO up and running on the aarch64 platform sooner, though we'll still want to switch over to android-x86 when possible since the profile generation is much faster on x86, and the arm emulator may be going away in the future.

No longer depends on: 1545497

Similar to bug 632954, this disables the Android aarch64 tests on opt
except on try, and instead runs the tests on Android aarch64 pgo builds.

Depends on D29588

:ekyle, can you handle updating the perf dashboards to adjust android /aarch64 data from opt->pgo?

:davehunt, do you have other questions or steps required before this lands? I can think of maybe an email to performance at moco

:davehunt, can you comment on this- we are ready to land.

I've informed the perf team, perf test team, and perf sheriffs of this upcoming change.
