Re: [PATCH] improve float to double on PPC a little


	Do matching constraints work correctly when the mode of the
operands differ?  When I tried this exact change a few years ago, I
encountered problems.

	If this now works, great, but I am concerned that this might
violate some assumption in the register allocator or reload.
