##@brief Execute cppcheck
##
##This bash script can be used to execute cppcheck for the tf-m project.
##It will use the CMake generated "compile_commands.json" file.
##CMake is executed to generate the build commands for the "default" build
##configuration (i.e. no build config file is specifyed on the command-line).
##
##This file shall be executed from the root directory of the tf-m working copy.
##
##In order to have all include file in place, some CMake external projects will
##be built, and thus C build tools for the default build configuration must be
##available.
##
##The script will generate two XML output files:
##file    | description
##--------|--------
##chk-config.xml | The result of cppcheck configuration verification.
##chk-src.xml. | The result of source file verification.
##
##@todo The current version of cppcheck seems to ignore command line parameters
##       when using the --project command line switch. As a result it is not
##       possible to define additional macros and include paths on the command
##       line. This results in some incorrect error and warning messages.
##@todo The file cppcheck/arm-cortex-m.cfg needs to be revised. Some settings
##      might be invalid, and also a differnet file may be needed based on
##      used compiler switches (i.e. to match witdh specification and or default
##      sign for some types).
##@todo Currently cppcheck is only executed for the default build configuration
##      "ConfigDefault.cmake"for target AN521 of the "top level" project.
##      This might need to be revied/changed in the future.
