NOTE
Go Build Process
From parsing and type checking through SSA/optimization, code generation, linking, modules, and build cache.
This is a historical learning note and may contain outdated or incomplete understanding.
The Go toolchain resolves modules/packages, parses and type-checks source, lowers functions into compiler IR/SSA, applies optimizations, generates target-machine code, and links the final binary or package archive.
Build behavior depends on the Go version, target (GOOS/GOARCH), build tags, cgo, linker flags, and module graph. The build cache avoids repeating unchanged compilation work. Treat compiler-internal phases and symbols as version-specific implementation details.
