I am using ARMv8 GCC compiler(aarch64-none-elf-gcc) for my bare metal application on ARM cortex a53. I am using neon intrinsics with plain C in my code so I would like to ensure to use all optimization option available for this compiler.
I tried -mfpu = neon but compiler is not recognizing it. So, what are the possible optimization option available for my application setting. I am using Xilinx SDK IDE for my application.
