How to change the eflags register value in GDB?

Question

set $eflags does not change eflags value.

The old eflags value remains after eg. =>$set $eflag=0x243 [this is just an example input].

Alternatively, is there any way to set individual flags of eflags?

I'm looking for something like: set ZF[zero flag]. Is there a gdb command to do that?

Answer 1

set ($eflags)=0x243

worked in my tests for any hex value.
