2.1.35. --diag_suppress=optimizations
This option suppresses diagnostic messages for high‑level optimizations.
By default, optimization messages have Remark severity. Specifying --diag_suppress=optimizations suppresses optimization messages.
Note
Use the --remarks option to see optimization messages having Remark severity.
The compiler performs certain high‑level vector and scalar optimizations when compiling at the optimization level -O3, for example, loop unrolling. Use this option to suppress diagnostic messages relating to these high‑level optimizations.
/*int*/ factorial(int n)
{
int result=1;
while (n > 0)
result *= n--;
return result;
}
Compiling this code with the options -O3 -Otime --remarks --diag_suppress=optimizations suppresses optimization messages.
