2.1.34 --diag_suppress=optimizations
This option suppresses diagnostic messages for high-level optimizations.
Default
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.
Usage
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.
Example
/*int*/ factorial(int n)
{
int result=1;
while (n > 0)
result *= n--;
