Code Generation

Understands what code generation is and the difference between native code, bytecode and interpretation. Knows basic concepts of register allocation and instruction selection. Can read x86/ARM assembly.

Generates simple code output from IR using template-based emitters. Understands the mapping from AST nodes to target language constructs. Writes basic tests verifying generated code correctness.

Reads generated assembly or machine code output from compiler backends. Understands basic instruction selection and register allocation concepts. Traces code generation paths to debug simple output issues.

Implements code generation for stack-based or register-based bytecode. Uses LLVM or QBE for native code generation. Generates optimized code for function call patterns.

Implements code generators targeting multiple output formats (source code, bytecode). Builds peephole optimizations and handles platform-specific code emission. Writes property-based tests for generated output validation.

Implements instruction selection and scheduling passes for target architectures. Works with register allocators and handles calling convention compliance. Writes extensive tests ensuring generated binary correctness across platforms.

Designs instruction selection and register allocation for a new target. Implements calling convention for custom ABI. Optimizes codegen for specific CPU architectures (x86/ARM/RISC-V).

Designs code generation pipelines with pluggable backends for multiple target platforms. Architects JIT compilation and incremental code generation strategies. Mentors the team on compiler backend design and optimization trade-offs.

Designs code generation backends targeting custom hardware and specialized ISAs. Architects auto-vectorization and SIMD code emission strategies. Mentors engineers on low-level optimization and hardware-software co-design.
