aarch64: Add flags field to aarch64-simd-pragma-builtins.def
This patch adds a flags field to aarch64-simd-pragma-builtins.def
and uses it to add attributes to the function declaration.
gcc/
* config/aarch64/aarch64-simd-pragma-builtins.def: Add a flags
field to each entry.
* config/aarch64/aarch64-builtins.cc: Update includes accordingly.
(aarch64_pragma_builtins_data): Add a flags field.
(aarch64_init_pragma_builtins): Use the flags field to add
attributes
to the function declaration.
