AArch64 can fill the vector registers with half precision floats. Add a view for this. Add builtin type ieee half and connect this to the existing floatformats_ieee_half. gdb/ChangeLog: 2019-05-14 Alan Hayward <alan.hayward@arm.com> * aarch64-tdep.c (aarch64_vnh_type): Add half view. (aarch64_vnv_type): Likewise. * target-descriptions.c (make_gdb_type): Add TDESC_TYPE_IEEE_HALF. * common/tdesc.c: Likewise. * common/tdesc.h (enum tdesc_type_kind): Likewise. * features/aarch64-fpu.c (create_feature_aarch64_fpu): Regenerate. * features/aarch64-fpu.xml: Add ieee half view. * features/aarch64-sve.c (create_feature_aarch64_fpu): Likewise. * gdbtypes.c (gdbtypes_post_init): Add builtin_half * gdbtypes.h (struct builtin_type): Likewise. (struct objfile_type): Likewise.
