thorpej 8969ba6ff5 Build _isinfl() and _isnanl(). 2003-05-17 15:05:52 +00:00
kleink db907cb577 Rename ieee754_function.c to function_ieee754.c, following the convention 
used in exec_format.c, loadfile_format.c, subsys_machdep.c etc.
Per discussion with Christos.

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 5d3e829423 Add internal names for fp{get,set}{mask,round,sticky}(), and 
externally-visible weak aliases for the internal names.

cgd 2eb1943575 make these more amenable to being copied into libkern. (Gee, why wasn't 
this done before?  it's not like it was hard...)

cgd 181fee6ea8 pull up <machine/endian.h> and use BYTE_ORDER to decide endianness, 
rather than MIPSEL and MIPSEB definitions.

mycroft 9cba4741ee Use C versions of isinf() and isnan(). The assembler code is basically 
identical, but was endian-dependent.

even tho _setjmp()/_longjmp() don't manipulate signals.  (more thought?)

bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

jonathan 68a9b35134 Do a .cpload if compiling with PIC. 
Examining  the .so output from binutils 2.8 and 2.8.1 shows the
	li.d	$f2, 4503599627370496e0
is (incorrectly?) emitted as GP-relative loads when PIC is in effect.

Leave the change in but commented out, it may be a  ld.so problem.
