答复: Will this ARM64 erratum patch be backported to this month's Linaro GCC 4.9 release?

Hi Yvan :

Thanks. other questions about this patch:

Will the patch stay in all arm64 compilers for ever? or someday it will be discarded for optimization reasons?

Would you provide a compiler option which enable or disable the patch during buiding and if so what the option is?

Thanks again.

Peter
