Hi All, 


Hi previous float immediate patches changed

aarch64_reg_or_fp_zero into aarch64_reg_or_fp_float
for each of the movdf/sf/hf causing the RTL to contain
stores to memory it would never be able to find a matching
pattern for. Reload would then decide to store them to a
register instead.

This didn't cause any incorrect code or failing tests but did change
scheduling does producing more inefficient code.

The predicate is not reverted.


Regression tested on aarch64-none-linux-gnu and no regressions.

OK for trunk?

Thanks,
Tamar
