aarch64: Fix up aarch64_print_operand xzr/wzr case
This adjusts aarch64_print_operand to recognize zero rtxes in modes other than
VOIDmode. This allows us to use xzr/wzr for zero vectors, for example.
We extract the test into a helper function, aarch64_const_zero_rtx_p, since this
predicate is needed by later patches.
gcc/ChangeLog:
* config/aarch64/aarch64-protos.h (aarch64_const_zero_rtx_p): New.
* config/aarch64/aarch64.cc (aarch64_const_zero_rtx_p): New.
Use it ...
(aarch64_print_operand): ... here. Recognize CONST0_RTXes in
modes other than VOIDmode.
