92d8b1e9fa Revert previous: .S files are currently compiled with -traditional-cpp, 
so __STDC__ is _not_ always defined.

010758bf16 Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new 
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.

2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

4b4c3144ba Enable the _Qp* routines to be built always and allow full softfloat to be 
pulled in if MKSOFTFLOAT gets enabled.

d9c86555ad Add softfloat and quad softfloat setup for sparc64 (thanks to Andrey Petrov 
for most of this. I just integrated the build).

This adds proper functions for the _Qp* parts of the sparc64 ABI (which
handle quad softfloat). The routines work but need additional testing.
However if the compiler calls these currently bad things (core dumps)
will happen as gcc 2.95.3 generates bad calls for these.

Until that problem is fixed in the toolchain -msoft-quad-float cannot be
enabled as the default option for all builds (but the routines need to be
in libc as libgcc contains some references to these and anything including
it via --whole-archive will need the symbols to at least resolve).

ac8c1c29e9 * Add WSYSCALL() to SYS.h, which creates a system call with an 
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).

26375a1710 Remove -Wa,-Av9a hack from <sys.mk> and relegate it to the places that need 
it (kernel and libc).

The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format.  "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.

case. Write ERROR() in terms of call.
