rsk7203_defconfig build error

[Adrian Bunk]

Hi Paul,

rsk7203_defconfig fails to build with the following error:

<--  snip  -->

...
  LD      .tmp_vmlinux1
arch/sh/kernel/built-in.o:(__ksymtab+0xb8): undefined reference to `__udivsi3_i4i'
arch/sh/kernel/built-in.o:(__ksymtab+0xc8): undefined reference to `__sdivsi3_i4i'
make[1]: *** [.tmp_vmlinux1] Error 1

<--  snip  -->

That worked with 2.6.26, and these are far less undefined references 
than in the cases where libgcc was missing.

Does it build with your toolchain?
Do you have any clue what's going wrong here?

Adrian

This functions is not defined sh2 and sh2a.
See gcc-4.3.1/gcc/config/sh/lib1funcs.asm

Sorry I forget report.

This works fine for my toolchains at least, so I'll apply it.

Thanks, that fixed the compilation for me.
