If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH; Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway. |

Readme.NetBSD
- Import new Motorola 060SP packages in /sys/arch/m68k/060SP first.
- if you had to change something in here, "make clean" here
- commit Makefile Readme.NetBSD makeas.sh makeoffs.awk
- "make" here
- commit this directory

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.
