Method:
Out of the table, we create a wrapper for fplsp.S. It contains:
Single precision:
movl sp@(4),sp@- 4
bsr _060fplsp+theoffset 4
fmovs fp0,sp@ 4
movel sp@+,d0 4
rts 2
(18 bytes)
Double precision:
movl sp@(4+0),sp@- 4
movl sp@(8+4),sp@- 4
bsr _060fplsp+theoffset 4
fmovd fp0,sp@ 4
movel sp@+,d0 4
movel sp@+,d1 4
rts 2
(26 bytes)
For __SVR4_ABI, the code is much shorter... it reduces to a single jbra.
