This patch replaces all inter-type references in the ctfc internal data structures with pointers, rather than the references-by-ID which were used previously. A couple of small updates in the BPF backend are included to make it compatible with the change. This change is only to the in-memory representation of various CTF structures to make them easier to work with in various cases. It is outwardly transparent; there is no change in emitted CTF. gcc/ * btfout.cc (BTF_VOID_TYPEID, BTF_INIT_TYPEID): Move defines to include/btf.h. (btf_dvd_emit_preprocess_cb, btf_emit_preprocess) (btf_dmd_representable_bitfield_p, btf_asm_array, btf_asm_varent) (btf_asm_sou_member, btf_asm_func_arg, btf_init_postprocess): Adapt to structural changes in ctf_* structs. * ctfc.h (struct ctf_dtdef): Add forward declaration. (ctf_dtdef_t, ctf_dtdef_ref): Move typedefs earlier. (struct ctf_arinfo, struct ctf_funcinfo, struct ctf_sliceinfo) (struct ctf_itype, struct ctf_dmdef, struct ctf_func_arg) (struct ctf_dvdef): Use pointers instead of type IDs for references to other types and use typedefs where appropriate. (struct ctf_dtdef): Add ref_type member. (ctf_type_exists): Use pointer instead of type ID. (ctf_add_reftype, ctf_add_enum, ctf_add_slice, ctf_add_float) (ctf_add_integer, ctf_add_unknown, ctf_add_pointer) (ctf_add_array, ctf_add_forward, ctf_add_typedef) (ctf_add_function, ctf_add_sou, ctf_add_enumerator) (ctf_add_variable): Likewise. Return pointer instead of ID. (ctf_lookup_tree_type): Return pointer to type instead of ID. * ctfc.cc: Analogous changes. * ctfout.cc (ctf_asm_type, ctf_asm_slice, ctf_asm_varent) (ctf_asm_sou_lmember, ctf_asm_sou_member, ctf_asm_func_arg) (output_ctf_objt_info): Adapt to changes. * dwarf2ctf.cc (gen_ctf_type, gen_ctf_void_type) (gen_ctf_unknown_type, gen_ctf_base_type, gen_ctf_pointer_type) (gen_ctf_subrange_type, gen_ctf_array_type, gen_ctf_typedef) (gen_ctf_modifier_type, gen_ctf_sou_type, gen_ctf_function_type) (gen_ctf_enumeration_type, gen_ctf_variable, gen_ctf_function) (gen_ctf_type, ctf_do_die): Likewise. * config/bpf/btfext-out.cc (struct btf_ext_core_reloc): Use pointer instead of type ID. (bpf_core_reloc_add, bpf_core_get_sou_member_index) (output_btfext_core_sections): Adapt to above changes. * config/bpf/core-builtins.cc (process_type): Likewise. include/ * btf.h (BTF_VOID_TYPEID, BTF_INIT_TYPEID): Move defines here, from gcc/btfout.cc.
