@@ -1,6 +1,13 @@ Release 1.8 =========== +- More faithful semantics for volatile accesses: + . volatile reads and writes from a volatile global variable are treated + like input and output system calls (respectively), bypassing + the memory model entirely; + . volatile reads and writes from other locations are treated like + regular loads and stores. + - Added "fabs" (floating-point absolute value) unary operator to Clight; map __builtin_fabs() to this operator. |
