Confirmed: OpenJDK JIT compiler emits efficient conditional move machine codes
Confirmed: OpenJDK JIT compiler emits efficient conditional move machine codes On popular programmers’ Q&A site stackoverflow.com the hit question of the last few years dealt with the effect of branching on program performance. I recommend that you read the brilliant explanation there, but if you don’t have much time, here’s the summary. Modern processors execute commands in a pipeline. While One

JIT compilation in modern platforms – challenges and solutions
This document discusses just-in-time (JIT) compilation techniques in modern runtimes. It outlines two main approaches to JIT - method-based compilation and tracing JIT. It then describes specific techniques used in the HotSpot JVM, including its fast interpreter, two-tiered JIT compilation, runtime profiling, devirtualization, incremental compilation, on-stack replacement, escape analysis and scal
Terra
Terra is a low-level system programming language that is embedded in and meta-programmed by the Lua programming language: -- This top-level code is plain Lua code. function printhello() -- This is a plain Lua function print("Hello, Lua!") end printhello() -- Terra is backwards compatible with C, we'll use C's io library in our example. C = terralib.includec("stdio.h") -- The keyword 'terra' introd
Hello, JIT World: The Joy of Simple JITs
This is a demonstration of how simple and enjoyable small JITs (just-in-time compilers) can be. The word “JIT†tends to invoke an image of deepest wizardry, something that only teams of the most hard-core compiler guys would ever dream of creating. It makes you think of the JVM or .NET, very large runtimes with hundreds of thousands of lines of code. You never see “Hello, World!†sized programs fo
