Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

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.
