Selectable Dual-Mode JIT Compiler for SIMD Instructions

摘要

A JIT (Just-In-Time) compiler performs dual-mode code generation by determining whether an application has opted-in to SIMD (Single Instruction Multiple Data) code generation both at JIT-time and at runtime. The application may select the code generation mode by identifying whether it has opted-in to SIMD code generation. As a result, the underlying implementation guarantees application compatibility by allowing the application to select the code generation mode. Additionally, applications have the ability to select into different code generation modes during concurrent execution.
