About the Coremark/DMIPS for Cortex-R52

Dear Arm Experts,

From the Cortex-R52 (arm.com), it shows:

2.09 / 2.72 / 5.99 DMIPS/MHz * 4.3 CoreMark/MHz .

Could you help provide the detail info, such as which compiler and the compiler options?

Because I got too low marks about the coremark and dmips on R52 in our SOC.

Thanks in advance,
