Under the hood of the HHVM JIT Compiler

A session at Northeast PHP 2014

Sunday 7th September, 2014

11:00am to 11:45am (EST)

There are about as many compilation strategies as there are PHP engines. The just-in-time (JIT) compiler inside Hip Hop Virtual Machine (HHVM), an open-source virtual machine designed for executing programs written in PHP and Hack, has been evolving quickly in the last year or two. Come hear the latest on how it compiles your standard PHP to optimized X86-64 machine code. HHVM uses a three-stage approach including an interpreter, profiling mode, an optimized mode, and we’re busy at work experimenting with LLVM.
