RE: [PATCH v1 1/1] Fix PR16193 - gdbserver aborts.

Pedro,

This should be the fix. The issue was that the buffer size was not matching the size actually read.
Macro was really broken, for any XCR0 value it was returning 576, as pointed by Joel:
https://sourceware.org/ml/gdb-patches/2013-11/msg00761.html

I have tested the macros on an ad-hoc application to verify its functionality.

Do you still see the issue when applying this?

Thanks for your review!
Regards,
-Fred

To be clear, this patch doesn't do any fix yet -- it's just a preparatory cleanup, right?
