The recent xgene tuning parameters merge broke the ARM bootstrap, since
the tables have been extended by an additional parameter giving:
gcc/config/arm/arm.c:1932:1: error: missing initializer for member
'tune_params::fuseable_ops' [-Werror=missing-field-initializers]
};
^
Fixed as below. I've no idea if this is the optimial behaviour for
Xgene parts, but it preserves the previous behaviour of the compiler
before this pass was added. I'll let those who really know decide
whether a more comprehensive change is needed.
R.
