Files

This file lists the MISRA-C:2004 compliance exceptions for the Freescale EWL C library. The exceptions listed cover all EWL C files and targets. However, we have only fully tested the PA and ARM targets for compliance at this point.

MISRA violations were detected using the PC-Lint 9.00d tool and the lnt/au-misra2.lnt checker file. To verify these results you can use the makefiles that are used to build a target's library files: 

  make -C ewl/EWL_C -f -f EWL_C.ARM_CORTEXM.mak misra 
  PLATFORM=ARM_CORTEXM \
  LNTDIR="/cygdrive/d/Lint" \
  LNTINCL="-iD:/Lint/lnt" \
  misra

This should list no MISRA violations or other PC-Lint warnings/errors. EWL uses EXCEPTION_RULE_*() macros to silence violations, e.g.: 

   #define MISRA_EXCEPTION_RULE_20_5() \
  /*lint -e{586} MISRA 2004 Rule 20.5: errno shall not be used 
  */

The exception macros are defined in the header file EWL_C/include/ewl_misra_types.h.
