* Remove sparc64 specific parts of libc.Warner Losh2020-02-261-542/+0
| | | | | | | | | | | | | | | Also update comments for which architectures use 128 bit long doubles, as appropriate. The softfloat specialization routines weren't updated since they appear to be from an upstream source which we may want to update in the future to get a more favorable license.

* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* - While SPARC V9 allows tininess to be detected either before or afterMarius Strobl2010-03-201-5/+10
| | | | | | | | | | | | | | | | rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and UltraSPARC processors defines that in all cases tinyness is detected before rounding, therefore rounding up to the smallest normalised number should set the underflow flag. - If an infinite result is rounded down, the result should have an exponent 1 less than the value for infinity.
