bjh21	936b7f4cf8	Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit ... version into different directories. Which version a given port uses is controlled by the SOFTFLOAT_BITS make variable. This is set to 64 (which uses the same code we had before) by default. 32-bit platforms that don't need extended precision support might get better performance by using 32. Set the ARM port to use the 32-bit version of SoftFloat, since this is more than a factor of two faster than the 64-bit version. This should get the floating-point performance back to what it was in 1.5.	2002-05-21 23:51:04 +00:00
bjh21	4472dbe5e3	Initial commit of SoftFloat 2a import. This should provide a sensible ... mostly-MI floating-point implementation for use by gcc -msoft-float. It's currently only used by arm26, but should be usable by other ports without too much hacking, assuming doubles and u_int64_ts are passed and returned the same way, and FP formats are IEEEish.	2000-06-06 08:14:49 +00:00
