+ Update all Cortex-M3/4F ports to trap a non interrupt safe API function being called from an interrupt handler. + Simplify the alignment checks in heap_4.c. + Update the MSVC Windows simulator demo to use heap_5.c in place of ...
+ Added RISC-V port for the IAR compiler. + Update the Windows simulator port to use a synchronous object to prevent a user reported error whereby a task continues to run for a short time after being moved to the Blocked state. Note we were not able to ...
