S/390 patch for initfini and memcopy/bcopy.




Hi,
we found a bug in the 64 bit version of initfini and I did some
optimizations
for memcpy/bcopy. Who would have thought that a loop of mvc's is faster
then
a mvcle?! Here are the two patches and the ChangeLogs:

2001-04-03  Martin Schwidefsky  <schwidefsky@de.ibm.com>

     * sysdeps/s390/s390-64/initfini.c: Fix __gmon_start__ GOT access.

(See attached file: initfini.diff)

2001-04-03  Martin Schwidefsky  <schwidefsky@de.ibm.com>

     * sysdeps/s390/s390-32/bcopy.S: Optimize for speed.
     * sysdeps/s390/s390-64/bcopy.S: Likewise.
     * sysdeps/s390/s390-32/mempcy.S: Likewise.
     * sysdeps/s390/s390-64/memcpy.S: Likewise.

(See attached file: mvc.diff)

blue skies,
