7092 * simplify-rtx.c (simplify_const_unary_operation): Use
7093 is_a <scalar_int_mode> instead of checking for a nonzero
7094 precision. Forcibly convert op_mode to a scalar_int_mode

7096 result modes and use the former when deciding what the value
7097 of a count-bits operation should be. Use is_int_mode instead
7098 of checking for a MODE_INT. Remove redundant check for whether
7099 this mode has a zero precision.

25576 entry for overloaded function argument types RS6000_BTI_bool_V4SI
25577 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
25578 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
25579 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
25580 Power9 for implementations of vec_cmpne. Change the signature for
25581 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
25582 (representing vec_all_ne) to remove the previously described first
25583 argument of type RS6000_BTI_INTSI, as this was an artifact of
25584 reliance on the AltiVec predicate framework, which is no longer
25585 used in the implementation of these functions. Add
25586 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
25587 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
25588 since, unlike the AltiVec predicate framework implementation, we
