* setjmp and longjmp were using the obsolete fstmiax and fldmiax
instructions.
* Because of a confusion with two different sets of names for the same
registers (r0...r3 and a1...a4), if VFP was present then the
subsequent check for iWMMXt support would use a register that had
been clobbered by saving/restoring the VFP registers. (The bit
being checked was clobbered by a reserved bit of FPSCR that it
always 0 on present hardware, and no present hardware has both VFP
and iWMMXt, so this did not cause visible problems.)

* sysdeps/arm/eabi/setjmp.S (__sigsetjmp): Replace deprecated
instruction fstmiax with vstmia.
Correct register conflict and comment.
* sysdeps/arm/eabi/__longjmp.S (__longjmp): Use vldmia not fldmiax.
Don't clobber r1/a2 register before testing IWMMXT hwcap.

This is the glibc ports repository, an add-on for the GNU C Library (glibc). It contains code that is not maintained in the official glibc source tree. This includes working ports to GNU/Linux on some machine architectures that are not maintained in the official glibc source tree. It also includes some code once used by old libc ports now defunct, which has been abandoned but may be useful for some future porter to examine. It may also include some optimized functions tailored for specific CPU implementations of an architecture, to be selected using --with-cpu. The ports repository is cooperatively maintained by volunteers on the <libc-ports@sourceware.org> mailing list, and housed in the glibc CVS as a module called "ports". See http://www.gnu.org/software/libc/resources.html for details on using CVS. To report a bug in code housed in the ports repository, please go to http://sources.redhat.com/bugzilla/ and file a bug report under the glibc "ports" component. An add-on for an individual port can be made from just the sysdeps/ subdirectories containing the port's code. You may want to include a README and Banner of your own talking about your port's code in particular, rather than the generic ones here. The real source code for any ports is found in the sysdeps/ subdirectories. These should be exactly what would go into the main libc source tree if you were to incorporate it directly. The only exceptions are the files sysdeps/*/preconfigure and sysdeps/*/preconfigure.in; these are fragments used by this add-on's configure fragment. The purpose of these is to set $base_machine et al when the main libc configure's defaults are not right for some machine. Everything else can and should be done from a normal sysdeps/.../configure fragment that is used only when the configuration selects that sysdeps subdirectory. Each port that requires some special treatment before the sysdeps directory list is calculated, should add a sysdeps/CPU/preconfigure file; this can either be written by hand or generated by Autoconf from sysdeps/CPU/preconfigure.in, and follow the rules for glibc add-on configure fragments. No preconfigure file should do anything on an unrelated configuration, so that disparate ports can be put into a single add-on without interfering with each other. Like all glibc add-ons, this must be used by specifying the directory in the --enable-add-ons option when running glibc's configure script. $Id$
