Dalvik JIT Compiler - Google Groups

    https://groups.google.com/g/android-platform/c/Mx1fVjb19TI
    The Dalvik team has been actively investigating what kind of JIT would work best over a wide range of memory- and power-constrained portable Android devices, and the code in AOSP master is an old...

Android Developers Blog: Dalvik JIT

    https://android-developers.googleblog.com/2010/05/dalvik-jit.html
    We added a Just In Time (JIT) compiler to the Dalvik VM. The JIT is a software component which takes application code, analyzes it, and actively translates it into a form that runs faster, doing so while the application continues to run. If you want to learn more about the design of the Dalvik JIT, please watch the excellent talk from Google I ...

Implementing ART Just-In-Time (JIT) Compiler | Android ...

    https://source.android.com/devices/tech/dalvik/jit-compiler
    The JIT compiler complements ART's current ahead-of-time (AOT) compiler and improves runtime performance, saves storage space, and speeds application and system updates. It also improves upon the AOT compiler by avoiding system slowdown during automatic application updates or recompilation of applications during over-the-air (OTA) updates.

Android Dalvik VM - eLinux.org

    https://elinux.org/Android_Dalvik_VM
    The Dalvik JIT, as of version 2.2, is a "trace-granularity JIT", which means that it compiles individual code fragments that it discovers at runtime to be "hot spots". (That is, it does not compile whole methods.)

[Q] Dalvik , aot and JiT | XDA Forums

    https://forum.xda-developers.com/t/q-dalvik-aot-and-jit.4193337/
    Both the Dalvik ( uses Just-In-time compiler, JIT ) and the ART ( what uses Ahead-Of-Time compiler, AOT ) are a Android runtime. ART is the default runtime since Android Lollipop. Knowing this you have to clarify what Android OS you are trying to hack. E. EasyToHack Member. Dec 15, 2015 17 7.

Tracing just-in-time compilation - Wikipedia

    https://en.wikipedia.org/wiki/Tracing_just-in-time_compilation
    A tracing JIT compiler goes through various phases at runtime. First, profiling information for loops is collected. After a hot loop has been identified, a special tracing phase is entered, which records all executed operations of that loop. This sequence of operations is called a trace.

Trace transitioning and exception handling in a trace ...

    https://dl.acm.org/doi/10.1145/2579673
    Trace-based Just-In-Time (JIT) compilation generates machine code for frequently executed paths (so-called traces) instead of whole methods. While this has several advantages, it complicates invocation of compiled traces as well as exception handling, so that previous trace-based compilers limited the way in which traces could be invoked.
