	Translate DW_TAG_GNU_annotation DIEs created for C attributes btf_decl_tag and btf_type_tag into an in-memory representation in the CTF/BTF container. They will be output in BTF as BTF_KIND_DECL_TAG and BTF_KIND_TYPE_TAG records. The new CTF kinds used to represent these annotations, CTF_K_DECL_TAG and CTF_K_TYPE_TAG, are expected to be formalized in the next version of the CTF specification. For now they only exist in memory as a translation step to BTF, and are not emitted when generating CTF information. gcc/ * ctfc.cc (ctf_dtu_d_union_selector): Handle CTF_K_DECL_TAG and CTF_K_TYPE_TAG. (ctf_add_type_tag, ctf_add_decl_tag): New. (ctf_add_variable): Return the new ctf_dvdef_ref rather than zero. (new_ctf_container): Initialize new members. (ctfc_delete_container): Deallocate new members. * ctfc.h (ctf_dvdef, ctf_dvdef_t, ctf_dvdef_ref): Move forward declarations earlier in file. (ctf_decl_tag_t): New typedef. (ctf_dtdef): Add ctf_decl_tag_t member to dtd_u union. (ctf_dtu_d_union_enum): Add new CTF_DTU_D_TAG enumerator. (ctf_container): Add ctfc_tags vector and ctfc_type_tags_map hash_map members. (ctf_add_type_tag, ctf_add_decl_tag): New function protos. (ctf_add_variable): Change prototype return type to ctf_dvdef_ref. * dwarf2ctf.cc (gen_ctf_type_tags, gen_ctf_decl_tags) (gen_ctf_decl_tags_for_var): New static functions. (gen_ctf_pointer_type): Handle type tags. (gen_ctf_sou_type): Handle decl tags. (gen_ctf_function_type): Likewise. (gen_ctf_variable): Likewise. (gen_ctf_function): Likewise. (gen_ctf_type): Handle TAG_GNU_annotation DIEs. gcc/testsuite/ * gcc.dg/debug/ctf/ctf-decl-tag-1.c: New test. * gcc.dg/debug/ctf/ctf-type-tag-1.c: New test. include/ * ctf.h (CTF_K_DECL_TAG, CTF_K_TYPE_TAG): New defines.

2023-04-28	Synchronize include/ctf.h with upstream binutils/libctf.	Roger Sayle
	This patch updates include/ctf.h to match the current libctf version in binutils' include/. I recently attempted to build a uber tree (following some notes that are so old they used CVS) and noticed that binutils won't build with gcc's top-level include, due to CTF_F_IDXSORTED not being defined in ctf.h. 2023-04-28 Roger Sayle <roger@nextmovesoftware.com> include/ChangeLog * ctf.h: Import latest version from binutils/libctf.
