For example, the following set of built-in operations allows to check overflow for addition:bool __builtin_add_overflow (type1 a, type2 b, type3 *res); bool __builtin_sadd_overflow (int a, int b, int *res); bool __builtin_saddl_overflow (long int a, long int b, long int *...

Google Share on Facebook arithmetic check [ə′rith·mə‚tik ‚chek] (computer science) The verification of an arithmetical operation or series of operations by another such process; for example, the multiplication of 73 by 21 to check the result of multiplying 21 by 73. ...
For example, using a 32-bit word allows an unrolled loop that checks for carries only after every 16 additions (Stevens, 1994) because it takes 16 additions in the worst case to have the carry overflow from bit 32. In addition, as noted in Chapter 5, the overhead of reading in the ...
a wider type to store the operands.This warning indicates that an arithmetic operation was provably lossy at compile time. This can be asserted when the operands are all compile-time constants. Currently, we check left shift, multiplication, addition, and subtraction operations for such overflows....
