e4dc8baa84 Provide sysarch(2) prototypes in the MD sysarch.h headers. While I'm
at it, use the ANSI C generic pointer type for the second argument,
thus matching the documentation.

Remove the now extraneous (and now conflicting) function declarations
in various libc sources.  Remove now unnecessary casts.

eaf21f315e Install the user trap handlers that libc provides from a constructor, so
that they will be installed before application constructors are invoked.
Its possible to link applications such that this fails, application code
is invoked before they are installed, but, well, Don't Do That.

8c93421144 Emulate ldq and stq (load/store long double) instructions. GCC has started
using these to load long doubles, but they aren't implemented in hardware
on (at least) UltraSPARC I and II machines.
Emulate popc in the user trap handler as well.
Re-arrange slightly to make support functions more accessible.

4895e965c3 Add userland floating point emulator code for sparc64. This is a port
of the (never committed) in-kernel version (with some optimizations and
cleanups), which in turn was ported from NetBSD.

6ce4e876a7 Add libc side of user trap handling.
Add support for handling floating point disabled traps mostly in userland
for the simple single threaded case.  Not yet enabled by default.
Implement __sparc_utrap_install as specified by the sparc abi.
