2021-01-27ld: depend on libctfNick Alcock3-0/+7
Since ld may depend on libctf (if present), and libctf may be relinked by the installation process, libctf must be installed before ld is, or the relink may fail if it calls on symbols or symbol versions that do not exist in any libctf already present on the system. (If none is present, the copy in the build tree will be automatically used, but if one *is* present, it may take precedence and break things.) (This is a maybe- dependency, so it will work even if libctf is disabled.)

Local symbols are of course supposed to be defined by their object file, but in other cases a local symbol is promoted to global by gas if undefined and referenced.

2021-01-19libctf, create: fix ctf_type_add of structs with unnamed membersNick Alcock5-0/+106
Our recent commit to support unnamed structure members better ditched the old ctf_member_iter iterator body in favour of ctf_member_next. However, these functions treat unnamed structure members differently: ctf_member_iter just returned whatever the internal representation contained, while ctf_member_next took care to always return "" rather than sometimes returning "" and sometimes NULL depending on whether the dict was dynamic (a product of ctf_create) or not (a product of ctf_open). After this commit, ctf_member_iter did the same. It was always a bug for external callers not to treat a "" return from these functions as if it were NULL, so only buggy callers could be affected -- but one of those buggy callers was ctf_add_type, which assumed that it could just take whatever name was returned from ctf_member_iter and slam it directly into the internal representation of a dynamic dict -- which expects NULL for unnamed members, not "". The net effect of all of this is that taking a struct containing unnamed members and ctf_add_type'ing it into a dynamic dict produced a dict whose unnamed members were inaccessible to ctf_member_info (though if you wrote that dict out and then ctf_open'ed it, they would magically reappear again). Compensate for this by suitably transforming a "" name into NULL in the internal representation, as should have been done all along. libctf/ChangeLog 2021-01-19 Nick Alcock <nick.alcock@oracle.com> * ctf-create.c (membadd): Transform ""-named members into NULL-named ones. * testsuite/libctf-regression/type-add-unnamed-struct*: New test.

2021-01-19libctf: lookup_by_name: do not return success for nonexistent pointer typesNick Alcock5-10/+45
The recent work allowing lookups of pointers in child dicts when the pointed-to type is in the parent dict broke the case where a pointer type that does not exist at all is looked up: we mistakenly return the pointed-to type, which is likely not a pointer at all. This causes considerable confusion. Fixed, with a new testcase. libctf/ChangeLog 2021-01-19 Nick Alcock <nick.alcock@oracle.com> * ctf-lookup.c (ctf_lookup_by_name_internal): Do not return the base type if looking up a nonexistent pointer type. * testsuite/libctf-regression/pptrtab*: Test it.
