How can I link the kernel with libgcc ?

Hi all,

I'm writing an audio driver and the hardware requires floating point arithmetic. When I build the kernel I get the following errors at link time:

*** Warning: "__subdf3" [sound/sh/siu_sh7343.ko] undefined!
*** Warning: "__muldf3" [sound/sh/siu_sh7343.ko] undefined!
*** Warning: "__divdf3" [sound/sh/siu_sh7343.ko] undefined!
*** Warning: "__adddf3" [sound/sh/siu_sh7343.ko] undefined!

These symbols are coming from gcc. What I would like to do is link the kernel with libgcc to solve this errors. I'm looking at the kernel makefiles and it doesn't seem obvious to me how to do it. Does anyone know how I can link the kernel with libgcc, or point me in the right direction ?

By the way this is for the Renesas SH7343 processor.

Thanks,

Carlos Munoz
