      Current workarounds are to mark the manipulated address as volatile or run at -O0, this will disable the compiler transformation causing the stall.

      uint32 volatile shift = ((*address + 1000U) << 5);

      For this source code ...

      typedef unsigned int uint32;
uint32 AddressManipulation(const uint32 * address)
{
    uint32 shift = ((*address + 1000U) << 5);
    
    /* Compilation hangs during translation while resolving the load/store of an address that has been manipulated by a shifted sum. */
    return *(volatile uint32 *)shift;
}
