re PR target/59799 (aarch64_pass_by_reference never passes arrays by value, contrary to ABI documentation)
2014-02-19 Michael Hudson-Doyle <michael.hudson@linaro.org>
PR target/59799
* config/aarch64/aarch64.c (aarch64_pass_by_reference): The rules for
passing arrays in registers are the same as for structs, so remove the
special case for them.
