Hi David,

Excellent! (or not, depending on the p.o.v. :-) ).  I'll try to analyze 
this.  I feared already that this wouldn't help powerpc, but this most 
probably is some confusion in the RTL move instructions generated on the 
edges.  No doubt I overlooked some target peculiarity in generating them 
:-(

Meanwhile Andrew has analyzed this somewhat (PR39929).  If that turns out 
to be correct we would need to amend the target to check for 
currently_expanding_to_rtl, not just for current_ir_type().  That wouldn't 
influence the AIX breakage though.


Ciao,
Michael.
