I don't know if the translators actually *fixed* the original manual during translation (because they have no permission to alter the original document AFAIK).

The actual result is of `movcf2gr` is `GR[rd][0] = CFR[cj] && GR[rd][GRLen-1 .. 1] = 0` and I have confirmed with the author of the original Chinese document that it is realy an ambiguity. He originally wanted to express `GR[rd][0] = CFR[cj]，GR[rd][GRLEN-1:1]=0`. This will be fixed in future document updates.

Yeah exactly. We're all fine then ;-)
