Richard,
This patch implements the target hook TARGET_FN_OTHER_HARD_REG_USAGE (posted
here: http://gcc.gnu.org/ml/gcc-patches/2013-03/msg01318.html) for MIPS, to
address the issue that $6 is sometimes used in split calls.

Build and reg-tested on MIPS.

OK for stage1?


Richard,

Ping.

This patch was submitted here ( 
http://gcc.gnu.org/ml/gcc-patches/2013-12/msg00771.html ) and is required for 
the -fuse-caller-save optimization which was submitted here ( 
http://gcc.gnu.org/ml/gcc-patches/2013-01/msg01234.html ).

The patch fixes a correctness issue with -fuse-caller-save for MIPS.

OK for stage1?

Thanks,
- Tom
