int* Register = 0x00FF0000; // Address of micro-seconds timer
while(*Register != 0);
Should I declare *Register as volatile while using armcc compiler and -O0 optimization ?
In other words: Does -O0 optimization requires qualifying that sort of variables as volatile ? (which is probably required in -O2 optimization)
