Coding Tips

Preprocessor defines, macros, inline functions

• Prefer using enum instead of preprocessor defines for constants
  • Preprocessor defines are only necessary when you are using the constant both in C and assembly sources
• Prefer using static inline functions instead of preprocessor macros
  • Preprocessor macros are only needed (a) for type polymorphism, (b) if the result needs to be an l-value (R/W accessor)
• Prefer using regular functions to static inline functions
  • Practically never needed, it is just premature optimization
