2024-06-12	PR 31882 libctf: test suite incorrect format specifiers	A. Wilcox	1	-1/+1

2021-03-18	libctf: fix some tabdamage and move some code around	Nick Alcock	1	-3/+3
	ctf-link.c is unnecessarily confusing because ctf_link_lazy_open is positioned near functions that have nothing to do with opening files. Move it around, and fix some tabdamage that's crept in lately. libctf/ChangeLog 2021-03-18 Nick Alcock <nick.alcock@oracle.com> * ctf-link.c (ctf_link_lazy_open): Move up in the file, to near ctf_link_add_ctf. * ctf-lookup.c (ctf_lookup_symbol_idx): Repair tabdamage. (ctf_lookup_by_sym_or_name): Likewise. * testsuite/libctf-lookup/struct-iteration.c: Likewise. * testsuite/libctf-regression/type-add-unnamed-struct.c: Likewise.
2021-01-05	libctf, testsuite: adjust for real return type of ctf_member_count	Nick Alcock	1	-3/+3
	This returns an int, not a long int or an ssize_t (as one test was inconsistently assuming). libctf/ChangeLog 2021-01-05 Nick Alcock <nick.alcock@oracle.com> * testsuite/libctf-lookup/struct-iteration.c (main): ctf_member_count returns an int.
2021-01-05	libctf, include: support unnamed structure members better	Nick Alcock	1	-0/+92
	libctf has no intrinsic support for the GCC unnamed structure member extension. This principally means that you can't look up named members inside unnamed struct or union members via ctf_member_info: you have to tiresomely find out the type ID of the unnamed members via iteration, then look in each of these. This is ridiculous. Fix it by extending ctf_member_info so that it recurses into unnamed members for you: this is still unambiguous because GCC won't let you create ambiguously-named members even in the presence of this extension. For consistency, and because the release hasn't happened and we can still do this, break the ctf_member_next API and add flags: we specify one flag, CTF_MN_RECURSE, which if set causes ctf_member_next to automatically recurse into unnamed members for you, returning not only the members themselves but all their contained members, so that you can use ctf_member_next to identify every member that it would be valid to call ctf_member_info with. New lookup tests are added for all of this. include/ChangeLog 2021-01-05 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h (CTF_MN_RECURSE): New. (ctf_member_next): Add flags argument. libctf/ChangeLog 2021-01-05 Nick Alcock <nick.alcock@oracle.com> * ctf-impl.h (struct ctf_next) <u.ctn_next>: Move to... <ctn_next>: ... here. * ctf-util.c (ctf_next_destroy): Unconditionally destroy it. * ctf-lookup.c (ctf_symbol_next): Adjust accordingly. * ctf-types.c (ctf_member_iter): Reimplement in terms of... (ctf_member_next): ... this. Support recursive unnamed member iteration (off by default). (ctf_member_info): Look up members in unnamed sub-structs. * ctf-dedup.c (ctf_dedup_rhash_type): Adjust ctf_member_next call. (ctf_dedup_emit_struct_members): Likewise. * testsuite/libctf-lookup/struct-iteration-ctf.c: Test empty unnamed members, and a normal member after the end. * testsuite/libctf-lookup/struct-iteration.c: Verify that ctf_member_count is consistent with the number of successful returns from a non-recursive ctf_member_next. * testsuite/libctf-lookup/struct-iteration-: New, test iteration over struct members. testsuite/libctf-lookup/struct-lookup.c: New test. * testsuite/libctf-lookup/struct-lookup.lk: New test.
