AM263P4-Q1: Is it possible to use GCC compiler instead of CLANG?

Tool/software:

Dear Champs,

My customer is trying to use commercial gcc compiler to develop SW for AM263P.

In this case, what is technical problem? Is there any issue to use TMU or other HW in AM263P?

I know we are not support other than CLANG and will inform this, but would like to check it technically.

For CLANG compiler,

have we certified functional safety for CLANG?

How customer can confident on the reliability of CLANG compiler?

Thanks and Best Regards,

SI.
