Re: [Suggestion] sh64: kernel: about the warning: "unexpected non-allocatable section".

[Chen Gang <gang.chen@asianux.com>]

For sh, it will report error below:

  [root@dhcp122 linux-next]# make ARCH=sh CROSS_COMPILE=sh-linux-gnu-
  CC      scripts/mod/empty.o
  as: unrecognized option '-little'
  make[2]: *** [scripts/mod/empty.o] Error 2
  make[1]: *** [scripts/mod] Error 2
  make: *** [scripts] Error 2

The related binutils information:

  [root@dhcp122 build-binutils-or32]# rpm -qf /usr/bin/sh-linux-gnu-ld
  binutils-sh-linux-gnu-2.23.51.0.3-1.fc17.x86_64
  [root@dhcp122 build-binutils-or32]# rpm -qf /usr/bin/sh-linux-gnu-as
  binutils-sh-linux-gnu-2.23.51.0.3-1.fc17.x86_64


Is it the binutils's issue ? is the warnings below is the binutils's
issue too? (now, I am downloading related tool chain source code of SH,
and will try again).


Thanks.
