S390: Vector ABI support
With the S390 vector ABI, vector registers are used for passing vector
arguments and for returning a vector. Support this ABI in inferior
function calls and when setting or retrieving a function's return
value.
gdb/ChangeLog:
* s390-linux-tdep.c: Include "elf/s390.h" and "elf-bfd.h".
(enum s390_vector_abi_kind): New enum.
(struct gdbarch_tdep)<vector_abi>: New field.
(s390_effective_inner_type): Add parameter min_size. Stop
unwrapping if the inner type is smaller than min_size.
(s390_function_arg_float): Adjust call to
s390_effective_inner_type.
(s390_function_arg_vector): New function.
(s390_function_arg_integer): Adjust comment.
(struct s390_arg_state)<vr>: New field.
(s390_handle_arg): Add parameter 'is_unnamed'. Pass vector
arguments according to vector ABI when appropriate.
(s390_push_dummy_call): Initialize the argument state's field
'vr'. Adjust calls to s390_handle_arg.
(s390_register_return_value): Handle vector return values.
(s390_return_value): Apply the "register" return value convention
to a vector when appropriate.
(s390_gdbarch_init): Initialize tdep->vector_abi.
* NEWS: Announce S390 vector ABI support.
