The FPXX and FP64A stuff is new, after I stopped tracking MIPS stuff, so I hadn't noticed it. I see why they added these, but if you count soft-float, single-float, no-float, and a now deprecated 64-bit FP reg mode, there are 8 different ways to handle FP code for o32. Crazy. Most of them aren't relevant to linux though. And I suppose 20-30 years from now RISC-V may have the same problem. Jim
