CMSIS-Core (Cortex-M) uses the common coding rules for CMSIS components that are documented in CMSIS Introduction.
CMSIS-Core (Cortex-M) violates the following MISRA-C:2012 rules:
- Directive 4.9, function-like macro defined.
- Violated since function-like macros are used to generate more efficient code.
- Rule 1.3, multiple use of '#/##' operators in macro definition.
- Violated since function-like macros are used to generate more efficient code.
- Rule 11.4, conversion between a pointer and integer type.
- Violated because of core register access.
- Rule 11.6, cast from unsigned long to pointer.
- Violated because of core register access.
- Rule 13.5, side effects on right hand side of logical operator.
- Violated because of shift operand is used in macros and functions.
- Rule 14.4, conditional expression should have essentially Boolean type.
- Violated since macros with several instructions are used.
- Rule 15.5, return statement before end of function.
- Violated to simplify code logic.
- Rule 20.10, '#/##' operators used.
- Violated since function-like macros are used to generate more efficient code.
- Rule 21.1, reserved to the compiler.
- Violated since macros with leading underscores are used.
