[PATCH] MIPS: In mips_print_address_operand pass the mode argument to mips_classify_address

[Andrew Bennett <Andrew dot Bennett at imgtec dot com>]

Hi,

Currently the mips_print_operand_address function ignores its mode argument, and when it calls
mips_classify_address it forces the mode argument to be the machine's word mode.  This patch
makes mips_print_operand_address pass the mode argument provided to it to mips_classify_address,
so that it uses the actual mode of the mem rtx.  This patch is also a pre-requisite for the
following patch: https://gcc.gnu.org/ml/gcc-patches/2016-05/msg00314.html.

I have tested the patch on the mips-mti-elf toolchain and there have been no regressions.

The patch and ChangeLog are below.


Ok to commit?

Many thanks,



Andrew
