Ganesh,

Thank you for your email - please note this question is best directed at linaro-toolchain@lists.linaro.org where it is more likely to get picked up quickly.

Our general rules for benchmarking are to use -mcpu=cortex-a## -O3 as the compiler flags (where ## is the particular CPU you are interested in).

Linaro's philosophy is to try and get the best results possible that normal users will see, we don't go looking for 'magic' options that may give better performance on one benchmark, but not in general.

Thanks,

Matt

Hi,

We would like to run some benchmarks in the foundation model. I like to know which is the best option-set (GCC compiler options) that the linaro community recommends for aarch64.
