V2.1.14

[RainerZ]

• xcpclient related changes:

  • Improved variable registration for global and static variables
  • Global variables and local static variables in functions without event trigger are registered, but not associated to any specific default DAQ event
  • Unique typedef names for struct/class types with the same name in different namespaces, classes or functions (motor_control.Input, valve_control.Input). Previously all variables of such types referenced the first registered typedef and were shown with the wrong type.
  • Global variables with the same name in different namespaces are registered with namespace qualified names (motor_control.input, valve_control.input) instead of dropping all but the first one
  • A struct type which is used for measurement and for calibration variables gets separate typedefs
  • The GCC declaration and definition entries of a namespace scope variable are merged, they no longer produce duplicate instance errors
  • Variables with internal linkage in a namespace and without DWARF location (e.g. metadata markers XCP_COMMENT(motor_control__input, ...) inside a namespace) are resolved by their mangled symbol name
  • Metadata annotations placed in the same namespace or function as the variable no longer need a scope prefix (XCP_COMMENT(input, ...) in namespace motor_control annotates motor_control.input), explicit prefixes keep working. Metadata for the typedef fields of namespace qualified instances.
  • Local variables without a DWARF location (optimized away) are no longer resolved to the address of a global variable with the same name, only symbols with local binding are considered for them
  • no_a2l_demo, no_a2l_demo_cpp: more demo cases, no_a2l_demo_cpp demonstrates types and variables with the same name in different namespaces

• Documentation: new docs/OFFLINE_A2L.md for the offline A2L generation with xcpclient (workflow, naming rules, supported types, diagnostics), docs/TECHNICAL.md keeps the library topics and the instrumentation marker contract, xcpclient and no_a2l_demo READMEs updated

• FreeRTOS related changes:

  • Allow custom memory attributes for queue32m
  • Avoid mutex allocation when queue32m uses critical sections
  • Support optional recursive FreeRTOS mutexes
  • Fix typos in FreeRTOS documentation and comments
  • Fix UDP segment size calculation from MTU
  • Make FreeRTOS queue segment count configurable
  • Support static allocation for FreeRTOS tasks and mutexes
  • Use static storage when configSUPPORT_STATIC_ALLOCATION is enabled
  • Preserve dynamic allocation and recursive mutex support
  • Update FreeRTOS documentation and remove obsolete queue TODOs
  • Fix FreeRTOS delay rounding and overflow
  • Avoid unaligned IPv4 address access in FreeRTOS/lwIP
  • Fix synchronization of FreeRTOS queue state
  • Correct FreeRTOS queue and lwIP documentation
  • Fix FreeRTOS emulator clock test build
