The Back End of a compiler is the final stage where further optimizations are performed, often specific to the target architecture, and machine code is generated.
In the Go compiler, the code is converted to Static Single Assignment (SSA)** form. Processes in this stage include:
- Generating SSA code.
- Lowering: Rewriting generic values to machine-specific ones.
- Register Allocation: Replacing variables with registers.
- Machine code generation.
