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.
