Inspect Go compiler optimizations by running go tool compile with the -m flag to see optimization decisions or -S for assembly output.
Use the -m flag with go tool compile to print optimization decisions, or -S to view the generated assembly.
go tool compile -m yourpackage.go
The -m flag outputs a list of optimizations applied, such as inlining, escape analysis, and constant folding, directly to standard output.
Inspecting compiler optimizations in Go reveals exactly what the compiler does to your code to make it faster. It lists specific changes like removing unused variables or combining functions. Think of it as a report card that explains how the compiler improved your program before turning it into machine code.
