ChangeLog for fpieee-ext.c

Unattributed changes are by David N. Williams.  Last revision
dates in source files may reflect cosmetic changes not recorded
here.

Version 0.5.2
 6Nov05 * Added caching of the rounding mode to circumvent
          longjmp() clobbering in the inner interpreter.
 7Nov05 * Revised comments for FEGETROUND and FESETROUND to
          conform with Single UNIX 3.

Version 0.5.1
29Aug05 * Changed return for SIGNBIT to an ANS Forth flag
          instead of a bit.

Version 0.5.0
21Jan05 * Start.
26Jan05 * Dereference bug in FESETEXCEPTFLAG.  Realized there
          will be a problem if TOS is ever a register.
27Jan05 * Added floating-point auxilliary functions and
          constants (not all).  Seem to have found a darwin bug
          in ilogb() vs. FP_ILOGB0 and FP_ILOGBNAN.  Also
          Harbison and Steele say FP_ILOGB instead of FP_ILOGB0.
 1Feb05 * Added FLOATING-EXT autoload, since the functions here
          use the floating point stack and numbers.
 3Feb05 * Added  P4_INTO ("EXTENSIONS", 0).
21Feb05 * Added MODF, MODFD.  Added FEXP2, FLOG2 in the new
          elementary functions section, which should eventually
          go in some other module.
22Feb05 * Added new elementary functions FCBRT, FMA, FDIM, FERF,
          FERFC, FGAMMA, FLNGAMMA.
23Feb05 * Changed FMA to F*+, and changed stack effect.
13May05 * Decided not to add the nonraising fp comparisons,
          because they seem of marginal use, and ordinary
          comparisons don't raise an exception anyway in our
          system.
