Use ctf_free, not ctf_free_base. 538 (upgrade_types): New, also handle ctf_parmax updating. 539 (flip_header): Flip ctf_cuname. 540 (flip_types): Flip BUF explicitly rather than deriving BUF from 541 BASE. 542 (ctf_bufopen): Store the header in fp->ctf_header.

Move 548 version-specific ctf_parmax initialization into upgrade_types. More 549 concise error handling. 550 (ctf_file_close): No longer test for null pointers before freeing. 551 Free ctf_dyncuname, ctf_dynbase, and ctf_header.

Remove obsolescent 557 comment. 558 (ctf_write): Likewise. 559 (ctf_compress_write): Get the header from ctf_header, not ctf_base. 560 Fix the compression length: fp->ctf_size never counted the CTF 561 header.

Construct the 614 strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the 615 rest of each buffer element is constructed, not via open-coding: 616 realloc the CTF buffer and append the strtab to it. No longer 617 maintain ctf_dtvstrlen. Sort the variable entry table later, after 618 strtab construction. 619 (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members. 620 (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref 621 after buffer element construction instead. 622 (ctf_copy_lmembers): Likewise. 623 (ctf_copy_emembers): Likewise. 624 (ctf_create): No longer maintain the ctf_dtvstrlen. 625 (ctf_dtd_delete): Likewise. 626 (ctf_dvd_delete): Likewise. 627 (ctf_add_generic): Likewise. 628 (ctf_add_enumerator): Likewise. 629 (ctf_add_member_offset): Likewise. 630 (ctf_add_variable): Likewise. 631 (membadd): Likewise. 632 * ctf-util.c (ctf_realloc): New, wrapper around realloc that aborts 633 if there are active ctf_str_num_refs. 634 (ctf_strraw): Move to ctf-string.c. 635 (ctf_strptr): Likewise. 636 * ctf-string.c: New file, strtab manipulation. 637 638 * Makefile.am (libctf_a_SOURCES): Add it. 639 * Makefile.in: Regenerate. 640 6412019-06-28 Nick Alcock <nick.alcock@oracle.com> 642 643 * ctf-impl.h (ctf_hash_iter_f): New. 644 (ctf_dynhash_iter): New declaration. 645 (ctf_dynhash_iter_remove): New declaration. 646 * ctf-hash.c (ctf_dynhash_iter): Define. 647 (ctf_dynhash_iter_remove): Likewise. 648 (ctf_hashtab_traverse): New. 649 (ctf_hashtab_traverse_remove): Likewise. 650 (struct ctf_traverse_cb_arg): Likewise. 651 (struct ctf_traverse_remove_cb_arg): Likewise. 652 6532019-06-28 Nick Alcock <nick.alcock@oracle.com> 654 655 * ctf-hash.c (ctf_dynhash_remove): Call with a mocked-up element. 656 6572019-06-28 Nick Alcock <nick.alcock@oracle.com> 658 659 * ctf-dump.c (ctf_dump_format_type): Prefix hex strings with 0x. 660 (ctf_dump_funcs): Likewise. 661 6622019-06-19 Nick Alcock <nick.alcock@oracle.com> 663 664 * ctf-open-bfd.c: Add swap.h and ctf-endian.h. 665 (ctf_fdopen): Check for endian-swapped raw CTF magic, and 666 little-endian CTF archive magic.
