Use boot image extension in the JIT-zygote experiment.
Test: temporarily enable JIT-zygote configuration, build, boot the
device and ensure that the JIT-zygote specific boot image
apex-framework.art is mapped in the zygote address space:
1. enable Jit zygote in the product device config (in my case
device/google/muskie/aosp_walleye.mk):
+# System server should not contain compiled code.
+PRODUCT_SYSTEM_SERVER_COMPILER_FILTER := verify
+
+# Use the apex image for preopting.
+DEXPREOPT_USE_APEX_IMAGE := true
+
+# Have the runtime pick up the apex image.
+PRODUCT_PROPERTY_OVERRIDES += \
+ dalvik.vm.boot-image=/apex/com.android.art/javalib/apex.art:/system/framework/apex-framework.art
2. lunch aosp_walleye-userdebug \
&& m \
&& adb reboot bootloader \
&& fastboot flashall -w
3. adb shell cat /proc/`adb shell ps | grep zygote64 | awk {'print $2'}`/maps | grep apex-framework.art
