Looks good.

So it is real failure in testing. Thank you for letting know.

Hi Ed,

Should it be +8 instead of +4? Or these offsets are not in bytes?: + unspill(rscratch1, true, srcoffset); + spill(rscratch1, true, dstoffset); + unspill(rscratch1, true, srcoffset+4); + spill(rscratch1, true, dstoffset+4); Ouch! Good catch.

So yes, it is not ideal that we are seeing these. The only ideal number for a regression suite is 0. However it is a separate issue and is on my list of things to look at. All the best, Ed.
