I already enabled FPU emulation, and I am sure that floating point is
not the issue. Two toolchains from uClinux have the different result,
one has the problem and another has  not. So I think it was caused by
toolchain. I am downloading the sources of the toolchains and try to
figure out the problem. Any idea? Thanks.
