quoting from softftp.S from 2.3.19:
* For now it's just a crude hack good enough to run certain fp programs
It's just dealing with denorms, NaNs, etc as inputs. AFAIK NetBSD was no
better until pretty recently.
Whether Linux or NetBSD, as systems, were ever serious MIPS run-time
systems---well, you wrote the book, so I'm inclined to get out of the
>From my LinuxCE perspective, a full FP emu is fairly important for getting
binary compatibility back with mainline Linux/MIPS---we've been in the
softfp ghetto. But most of what we do with FP is, uh, keep /bin/df happy
when it tries to calculate the percentage of free disk space, and the like.
And dropping softfp means we don't *have* to maintain a forked
(of course, getting rid of softfp makes mips16 more...interesting...)
