simonb 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).

thorpej 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()).

msaitoh cf9f94a483 sync with other archs. 
Important fixes:

 > ldexp(denormal, exp>1023) would generate the wrong result in all non-overflow

itojun 9870327734 fix syscall() and __syscall(). r0 has to be set to SYS_syscall or 
SYS___syscall, respectively.  otherwise sys/arch/sh3/sh3/trap.c will
look at the wrong argument.

bjh21 3b9cd873cb Revert previous change -- turned out I'd got my build environment in a twist. 2000-07-15 15:07:34 +00:00
bjh21 985033a7a6 Add fixunssfsi and fixunsdfsi. These are provided by libgcc2.c in GCC 2.95, 
but not in EGCS.

This version of fixunssfsi is almost exactly the arm32 version.  fixunsdfsi is
mostly based on fixdfsi, but with simplifications for 64-bit integers.

Only minimal testing has been applied so far.

itohy af83a97717 Add special treatment of shmat(2). 
On m68k ELF calling standard (__SVR4_ABI__), if a function
returns a pointer, the return value should go to a0 as well as d0.

cgd d220ca5ba3 fix up NetBSD RCS Ids to match the standard, and the leading comment as 
to match as well.  No functional changes.
