@sdardis ping.  I think the approach I've used for O32 is probably the right one in that it matches what DWARF expects (DWARF doesn't treat the 32-bit floating point registers as pairs but as individual registers).  I think the question is if I O32 with 32-bit FP registers should use an array of float[]s instead of an array of double[]s though (which adds an extra #ifdef for context size) vs keeping the current layout.
