[PATCH] MIPS: Prevent the p5600-bonding.c test from being run for the n32 and 64 ABIs

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

Hi,

The MIPS p5600-bonding.c test is currently failing for the n32 and n64 
ABIs.  The test is checking if the load/store bonding patterns correctly 
match sequences of load/store instructions.  There are currently no load/store 
bonding patterns to match DI mode values.  For the n32 and n64 ABIs the code 
generated for the testcase produces DI mode load and stores; which means the 
load/store bonding patterns are not matched and the test fails.	

To fix this issue I have added a dg-skip-if option to the test to prevent it
from being run for the n32 and n64 ABIs.  When support for load/store bonding
for DI mode values has been added this can be removed.

The patch has been tested on the mti/img elf/linux-gnu toolchains, and
there have been no new regressions.

The patch and ChangeLog are below.

Ok to commit?


Many thanks,



Andrew
