ARM GCC errata bug fix

Hi all,

I'm using the GCC ARM compiler in version (GNU Tools for ARM Embedded Processors 6-2017-q2-update). I wanna know that whether the two arm errata:

1.Arm Errata 752770: Interrupted loads to SP can cause erroneous behavior

2.Arm Errata 838869: Store immediate overlapping exception return operation might vector to incorrect interrupt

have been solved in this compiler? 

I recognize that these two errata may cause potential unexpected behavior to my system, so it is important for me to evaluate the errata effect. I can't confirm whether GCC has do something about the errata and hope someone could know it, thanks a lot!
