Questions tagged [dynamic-compilation]

Questions about code compilation in runtime. Alternatively, "Just-in-time compilation", "dynamic translation" or "runtime compilation". Used mostly by the runtime environment of tokenizing or interpreted languages.

Questions about code compilation in runtime.

Advantages

  • Compilation can be optimized for the current runtime system. This information is normally unavailable in compilation time.
  • Compilation to binary code is possible even independently from the CPU architecture.
  • Compilation can happen into memory, resulting platform-independent code combined with nearly binary code performance.

Disadvantages

  • Compiler must be part of the runtime environment.
  • Slow startup time.
  • Compile-time errors might appear only in runtime.
