Please see the
Trivial code generation stupidity thread:
http://gcc.gnu.org/ml/gcc/2001-12/msg00907.html
which evolved into the
cant_combine_insn_p hard_reg->reg moves thread:
http://gcc.gnu.org/ml/gcc/2001-12/msg01283.html
This is a general difficulty of GCC handling argument registers. The new
register alloctor will allow us to start addressing it.
