Caveat: No support for MPX on x32.


What would it take to support that?

About your question on x32 and MPX.
MPX does not support 32bit pointers in 64bit mode.


Ok, so IIUC, it's not a GDB limitation, or a limitation of this patch set.
It's really that x32 can't support MPX at all.  Correct?

Thanks,
Pedro Alves


That is correct.

Thanks,
