The code in the "encumbered" repository works for me.

Thanks for your quick reply.
In cpu/thread_context.hh there is a (virtual) function
"TheISA::PCState pcState()" which returns a copy of the PCState and a
function "void pcState(const TheISA::PCState &val)" to overwrite the
PCState obj.
I could call tc->pcState() to get a local copy of the PCState-obj and
copy it to a new place in memory called "modified_copy" (so that it
would not get deleted). Then I could change the PC and NextPC and call
tc->pcState(modified_copy).
However, this would result in a memory-leak, since the original
PCState-obj will not be deleted.
Kind regards,
Max

You'd read out the PCState object, change it, and then write it back.
The accessors are now mostly part of the PCState object as defined by
the ISA. If you're using Alpha we already have EIO support in the
"encumbered" mercurial repository which you can add to the build with
the EXTRAS scons command line variable.

Dear M5 users,
I have a patch for EIO support on M5. However, therefor I need to
change the program counter (and next PC).
I noticed that the source of M5 recently changed its way to modify the
PC and NextPC. There were setters in the past to do this, but now
there is this "PCState" object.
Does anybody know how I can change the PC and NextPC of a
ThreadContext object?
Thank you very much!
Regards,
Max
