I read the JIT Interface chapter and faced the problem: how to write a simpliest example for simpliest possible code (preferably in C++ and at least for x86-64 platform)? Say, I want to debug the f...

I have been looking into the Java JIT compiler and i cannot figure out why some of the code is still interpreted. Why doesn't the JIT compiler translate everything to native code? Interpretation is...

I'm looking at writing a JIT compiler for a hobby virtual machine I've been working on recently. I know a bit of assembly, (I'm mainly a C programmer. I can read most assembly with reference for op...

For one reason or another, I sometimes find it useful or just interesting to look at the optimised compiler output for a function. For unmanaged C/C++ code, my favourite way to do this has been to...

I am trying to write a program to JIT some code. The JITTed code needs to make calls back into the running application for run-time support and the run-time support symbols are not found when the f...

I've set-up everything as best as I can and yet I see JIT status as Disabled. Here's what I have: echo (function_exists('opcache_get_status') && opcache_get_status()['jit']['enabled']) ? ...

What is the simplest way to detect if PHP is compiled with JIT and JIT is enabled from the running script?

We have a server application with java IO operations. When running the application, we have observed CPU usage for CompilerThread0 and CompilerThread1 taking 45% and 41% CPU. The application is ser...

I've been looking for some guidelines regarding the optimal value of opcache.jit_buffer_size. The proposed values are up to 256M (e.g. https://php.watch/versions/8.0/JIT#jit-opcache.jit_buffer_size...

From Efficient R programming the byte compiler and R docment r byte compiler, I learnt that cmpfun can be used to compile a pure R function into byte code to speed and enableJIT can speed up by ena...

It's kind of subjective, but I'm having troubles getting LLVM JIT up to speed. Jitting large bodies of code take 50 times as much time as just interpreting them even with lazy compilation turned on...

I'd like to write a very small proof-of-concept JIT compiler for a toy language processor I've written (purely academic), but I'm having some trouble in the middle-altitudes of design. Conceptually...

I'm building a Next JS website and running Tailwind with JIT. This is my tailwind.config.js: module.exports = { mode: "jit", purge: ["./pages/**/*.{js,ts,jsx,tsx}", "./c...

My understanding is that Flutter is compiled AOT. Can it be compiled as JIT instead of AOT, will it work and what is the switch that would do that? Thanks!

I am trying to call a function - that should have an absolute address when compiled and linked - from machine code. I am creating a function pointer to the desired function and trying to pass that ...

I have the following Java code (all arrays are initialized before we call "arrays" and all are of size "arraySize") int arraySize = 64; float[] a; float[] b; float[] result; p...

Preamble This is about improving message send efficiency in a JIT compiler. Despite referring to Smalltalk, this question applies to most dynamic JIT-compiled languages. Problem Given a message...

Both of them pretty much do the same thing. Identify that the method is hot and compile it instead of interpreting. With OSR, you just move to the compiled version right after it gets compiled, unl...

The code is here: import numba as nb import numpy as np @nb.njit def func(size): ary = np.array([np.arange(size),np.arange(size)+1,np.arange(size)-1]).T X = np.array([ary[1:,0] - ary[:-1,2], a...

Doing migration for application form angularjs to angular v13 right now i'm trying to dual boot the application. and getting the following error in browser console: Uncaught Error: The injectable '...

I would like to alloc a buffer that I can execute on Win32 but I have an exception in visual studio cuz the malloc function returns a non executable memory zone. I read that there a NX flag to disa...

In the context of a scientific computing pipeline implemented in Java, we are using a LeastSquare optimizer from Apache Commons math 3.6.1 and experience strange numerical differences between Java ...

I'm using C#.NET for a web application. I've read that JIT compilation happens at run-time, which means(correct me if I'm wrong) that the compilation will happen when the request hits IIS. Another...

For example : Code 1: void Main() { Console.WriteLine("Some texts"); } Code 2: void Main() { Foo(); } void Foo() { Console.WriteLine("Some texts"); } Does code 2 run slower than code 1 ? ...

This question is related to android system. Dalvik VM uses JIT concept, it means that when you first run application Dalvik VM compiles it and loads into RAM as long as it could stay there. I under...
