[PATCH] Add MIPS ufr macro instruction

Hi,

This patch adds the ufr macro instruction.  The instruction allows user mode to change the value of the FR mode bit.  I have added a macro into the gas MIPS backend that translates the ufr instruction to the appropriate ctc1 instruction.  The patch is attached, and the ChangeLog entry is below.

This is my first patch to binutils, so I am unsure the protocol on committing.  Would someone be able to clarify?

Many thanks,


Andrew
