Go Compiler & defer: Bootstrap, Three defer Implementations, panic/recover & Closures
The article discusses the Go compiler and its implementation of the defer mechanism. It outlines the program lifecycle from the initial instruction to the final binary and highlights the various strategies used for defer execution. Additionally, it touches on performance optimization techniques and the intricacies of Go's runtime internals.
- ▪Go's compiler is entirely self-hosted, written in Go itself without relying on C or LLVM by default.
- ▪The defer mechanism in Go has three different implementations, each with unique performance characteristics.
- ▪The article emphasizes the importance of measuring performance before optimization using tools like pprof and trace.
