There is special code in libctf to handle typedefs with no name, which the code calls "anonymous typedef nodes". These monsters are obviously not something C programs can include: the whole point of a ttypedef is to introduce a new name. Looking back at the history of DWARF in GCC, the only thing (outside C++ anonymous namespaces) which can generate a DW_TAG_typedef without a DW_AT_name is obsolete code to handle the long-removed -feliminate-dwarf2-dups option. Looking at OpenSolaris, typedef nodes with no name couldn't be generated by the DWARF->CTF converter at all (and its deduplicator barfed on them): the only reason for the existence of this code is a special case working around a peculiarity of stabs whereby types could sometimes be referenced before they were introduced. We don't need to carry code in libctf to handle special cases in an obsolete OpenSolaris converter (that yields a format that isn't readable by libctf anyway). So drop it. libctf/ChangeLog 2021-01-27 Nick Alcock <nick.alcock@oracle.com> * ctf-open.c (init_types): Rip out code to check anonymous typedef nodes. * ctf-create.c (ctf_add_reftype): Likewise. * ctf-lookup.c (refresh_pptrtab): Likewise.

final link).

||
(ctf_serialize): Handle the !LCTF_LINKING case by writing out an
|
||
indexed, sorted symtypetab (and allow SYMFP to be NULL in this
|
||
case). Turn sorting off if this is a non-final link. Only delete

nonstatic vars if we are filtering symbols and the linker has
|
||
reported some.

|
||
test, testing survival of symbols across ctf_write paths.
