Hi,

    I am working on a FPU-less 34k MIPS platform with linux-2.6.24
kernel. After running a Darwin media streaming server on the board
for a while, my oprofile results shows high utilization on
fpu_emulator_cop1Handler() & r4k_wait().

wiki page http://www.linux-mips.org/wiki/Floating_point says gcc will
use hard float as default and soft float is best suited model for a
fpu less processor.  Could anyone kindly help me in understanding use
of -msoft-float .
Whether I need to compile

1. kernel with -msoft-float ? or
2. Glibc ? or
3. Application ? or
4. All the above ?

Thanks in Advance

Jabir
