General Guidelines
- Encapsulate and isolate assembly language
- Code shall not be "commented out"
- No use of floating-point arithmetics
- No hiding of identifiers defined in outer scopes
- Typedefs are unique (device_t?)
- Functions shall have prototype declarations
- Local functions should be declared static
- No definitions in header files
- All variables are assigned before use
- All objects should have fully qualified types (unsigned int instead of unsigned)
- We suggest trying to import more such rules, such as additional ones described in MISRA-C 2012 (Guidelines for the use of C in critical systems)
Required guidelines
Assembly language shall be encapsulated and isolated.
Assembly instructions should be encapsulated in either assembler functions, C functions or macros.
