[cfarm-users] GCC119 (AIX), GDB 7.9.1, and unable to display VMX regs

[Jeffrey Walton]

Hi Everyone,

I'm working on GCC119 which is an AIX machine. Its a Power 8, so it
has the VMX unit.

I'm trying to use the in-core crypto. The instructions are gets
processed by the VMX unit. I need to see the reg values, but GDB
cannot print them (see below).

Does anyone know how to display the registers when working on AIX?

Thanks in advance.
