Yes, I posted a series of patches that fix this problem and other rtx costs.
Look for patches with "rs6000_rtx_costs" in the subject. Some of the patches
were even approved, but not all in the series. I am disillusioned enough with
gcc that I won't be pushing those patches or attempting any future gcc work.
You or anyone else are welcome to pick up the pieces.
