MIPS testsuite patch for --with-synci configurations

MIPS testsuite patch for --with-synci configurations

[Steve Ellcey]

This patch is to fix MIPS failures that occcur when configuring GCC with the
-with-synci option.  In this case GCC will generate the synci instruction
by default if on a MIPS architecture that supports it .  When on an
architecture that does not support synci, GCC will not generate it by default
but it does generate a warning saying that it is not doing so and that
warning is causing tests that explicitly specify a MIPS architecture that
does not support synci but do not explicitly turn off synci to fail with an
extra, unexpected warning.

I initially looked at changing GCC to remove the warning but that did
not look workable, see http://gcc.gnu.org/ml/gcc/2012-06/msg00100.html
for more details.

This patch addes the -mno-synci flag to MIPS tests that specify an
architecture that does not support synci, thus getting rid of the
warning message and making the tests pass.  Tested with the mips-linux-gnu
and mips-sde-elf targets both with and without --with-synci on the
GCC configuration.

OK to checkin?

I wonder if it would make more sense to modify the testsuite driver to 
take care of this.  It seems like the set of files with the -mno-synci 
annotation could easily become different than the set that requires it.

I did think about that, but the number of flags that I would have to
check for in the testsuite driver to decide whether or not to turn on
-mno-synci was large enough to make me not want to do it that way.

I would need to check the isa= and isa_rev= flags that are currently
handled in the driver, the -mabi flag, the -march flag, and the -mips
flag.  The number of values that each flag could have (particularly
-march) is rather large.  I can imagine people adding a new test and
forgetting to add -mno-synci but that would be easy to fix and no worse
then adding a new -march value and not handling it in the test suite
driver.

I agree with David.  This is really the same kind of situation as we
already have for -m(no-)dsp, etc.  There too we need to override an
explicit -mdsp (which might be added using --target_board, etc.)
when testing a target that doesn't support the DSP ASE.

I think the patch below should be enough.  Spot-checked on mips64-elf
using --target_board mips-sim-idt64/-mips64r2/-msynci.  Could you
give it a go with your target?

Thanks,
Richard

Excellent, this patch works great and fixed all the unexpected failures
I was getting due to --with-synci.  I guess I need to study mips.exp a
bit more to understand all of what it can do.
