No. Unfortunately it's not possible to use the regular ttrace mechanism
to set the pcsqh/pcsqt (aka iasq[0] and iasq[1]) registers.... bascially
you need to execute a bit of code:
(assuming pcoqh (aka pc) is in r21 and pcsqh is in r22)
ldsid (%r22), %r1
mtsp %r1, %sr0
be 0(%sr0, %r21)
this branches to (%r22, %r21), thereby setting the space register ...
