Compiler Command-line Options
2.1.36 --diag_warning=optimizations
This option sets high-level optimization diagnostic messages to have Warning severity.
Default
By default, optimization messages have Remark severity.
Usage
The compiler performs certain high-level vector and scalar optimizations when
compiling at the optimization level -O3 -Otime, for example, loop unrolling. Use this
option to display diagnostic messages relating to these high-level optimizations.
Example
int factorial(int n)
{
int result=1;
while (n > 0)
result *= n--;
}
return result;
Compiling this code with the options --vectorize --cpu=Cortex-A8 -O3 -Otime
--diag_warning=optimizations generates optimization warning messages.
