Rask,
The problem here is that the port is defining EH_RETURN_STACKADJ_RTX to
be the pseudo reg (reg:HI 49). This sounds very wrong to me.
The df scanning code is making this an artificial use in the exit block.
However, there are no other uses or defs of reg 49 in this function.
This causes problems.
Kenny
