+ Here's a AMD64 example that deals with FP values:
+ @example
+ abi-code my-f+  ( r1 r2 -- r )
+ \ SP passed in di, returned in ax,  address of FP passed in si
+ si )     ax mov         \ load fp
+ax d)  dx lea         \ update fp
+ ax )   xmm0 movsd       \ r2
+ dx )   xmm0 addsd       \ r1+r2
+ xmm0   dx ) movsd       \ store r
+ dx     si ) mov         \ store new fp
+ di       ax mov         \ sp into return reg
