Following demo code will generate float point instruction "lfd" by
compile it with command "powerpc-linux-uclibc-gcc demo.c -S". Since
the actual working code is a part of linux kernel,  I just wanna
suppress the generation of float point instructions. Is there any
way(some gcc flags for example) to finish this job?


-msoft-float .  This flag is set by the PowerPC Linux
build system automatically already.
