quoting from softftp.S from 2.3.19:
* For now it's just a crude hack good enough to run certain fp programs
like
* Mozilla.
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
argument.
>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
toolchain/libc.
(of course, getting rid of softfp makes mips16 more...interesting...)
