I'd like to remind people that the include/math-emu code is based on an old, buggy version of the soft-fp code in glibc. RTH previously noted that the fixes should go in the kernel, when approving a patch of mine fixing various bugs and speeding up soft-fp, and several more bugs have been fixed since then in the course of GCC work on soft-float for Power and __float128 support for x86_64. So it may be better than the old code you're replacing, but it might still be a good idea to merge things with the current glibc code, as a matter of both correctness and performance. (And there may well still be bugs left in the code.) -- Joseph S.
