Macros | |
| #define | ACCESS_ONCE(x) (*(volatile typeof(x) *)&(x)) |
| Purpose of this macro is to force compiler to access variable exactly at the place it's written (no moving around and changing places with other variables reads or writes) and to avoid optimizations when several usages of local variable are replaced with direct access to global variable which should be read/written only once.
