Can Go's `go build` Command Accept Optimization Flags?

Optimizing Go Compilation

When compiling a Go program using go build myprogram.go, you may wonder if it's possible to pass optimization flags to enhance code performance, code size, or other aspects.

Go Compiler Optimizations

Unlike GCC compiler, the official Go compiler does not provide explicit optimization flags. However, the Go compiler applies various optimizations automatically, which are documented on the Go wiki here. These optimizations include:

• Escape analysis
• Garbage collection
• Constant propagation
• Loop optimizations
• Inlining

Disabling Optimizations

For debugging purposes, you can disable optimizations and inlining in the Go gc compiler using the following flags:

-gcflags '-N -l'

Where:

• -N disables optimizations.
• -l disables inlining.

Please note that disabling optimizations may result in slower code execution and larger code size.
