Description:
Sparkplug is a non-optimizing JavaScript compiler released with V8 v9.1 that aims to improve the performance of initial JavaScript execution. Unlike traditional optimizing compilers, Sparkplug compiles directly from bytecode rather than JavaScript source, allowing for faster compilation. By skipping the generation of intermediate representation (IR), Sparkplug emits machine code in a single linear pass over the bytecode, resulting in a simple and fast compiler. This approach enables Sparkplug to aggressively tier up to Sparkplug code, bridging the gap between the Ignition interpreter and the TurboFan optimizing compiler.
