14ee9d52aa * Made constants DP1,DP2,DP3 local to function rem_pio2, because their values are correct only for double-precision calculations.

d1348d3f9b - i386 and x86_64: Once softfloat stuff has been cleaned up, SysResetFPU and SysInitFPU end up doing exactly the same. Removed one of them.

0236c2823a + added startup modules for compact, large and huge model that define the 
memory model and include the common startup code prt0comn.asm (which is not
  yet adapted for the new models, but eventually will be)

f4c463b6bd * prt0stm.asm renamed prt0comn.asm, as it will probably be used as the common

dfa1f3e0a3 * NativeInt and NativeUInt redefined as aliases to PtrInt/PtrUInt, so now they 
become 32-bit in some i8086 memory models. Added comment explaining why they
  were introduced (delphi compatibility) and why they shouldn't be used in the
  FPC RTL.

531c2d79e0 - RTL: removed 'unimplementedwidestring' procedure and use 'unimplementedunicodestring' instead. Reduces bloat. Furthermore, a separate message about missing widestring manager is misleading, because there is only one wide/unicodestring manager that can be set.

94a045aa3d * Moved declarations of TFPURoundingMode,TFPUExceptionMask and TFPUPrecisionMode to System unit. Declarations in Math unit changed to aliases. 
* Changed type of softfloat_exception_mask and softfloat_exception_flags to TFPUExceptionMask, softfloat_rounding_mode to TFPURoundingMode.
- Cleaned out numerous conversions happening when getting/setting exception mask and rounding mode.

cfd2600b24 - Don't include softfpu code on SPARC, unless bootstrapping with 2.6. 
- Atari is never compiled on SPARC or MIPS (and even it does one day, softfpu is not needed).

dcb46051c4 * Get rid of last softfloat dependencies in genmath.inc. Replaced remaining calls to float_raise with expressions which generate appropriate floating-point exceptions at runtime. This is probably somewhat slower on actual softfloat targets, but the change only affects exceptional control flow, so not a significant issue.

fffc317759 * Replaced fpc_round_real with new implementation, having the following important properties: 
- it does not directly depend on softfloat stuff.
  - it triggers 'inexact' condition in a way compatible to hardware instructions (second assertion in webtbs/tw3157.pp now works correctly).
