* MFC r304055:markj2016-08-312-1/+7
| | | | Fix handling of forward enum declarations in the CTF tools.
* MFC r277300 (by smh): Mechanically convert cddl sun #ifdef's to illumosmav2016-03-208-20/+20
| | | | | | | | | Since the upstream for cddl code is now illumos not sun, mechanically convert all sun #ifdef's to illumos #ifdef's which have been used in all newer code for some time. Also do a manual pass to correct the use if #ifdef comments as per style(9) as well as few uses of #if defined(__FreeBSD__) vs #ifndef illumos.
* MFC r289866:markj2015-11-131-0/+4
| | | | | | | | DWARF emitted by clang 3.7 encodes array sizes using the DW_AT_count attribute rather than DW_AT_upper_bound. Teach ctfconvert about this so that array type sizes are encoded correctly. PR: 203772

| | | | | Illumos issue: 3363 Mark non-returning functions in ctftools
* MFC r260880 (by kaiw, from projects/elftoolchain):dim2014-03-291-8/+72
| | | | | | | | | | | | | | | | | | | * Make die_mem_offset() be able to handle DW_AT_data_member_location attributes generated by Clang 3.4. * Document how different compilers generate DW_AT_data_member_location attributes differently. * Document the quirks about DW_FORM_data[48]. This is a slightly modified version, adapted to work with the old libdwarf in stable/9 and stable/10. It should fix DTrace on these branches, when the kernel is compiled with clang 3.4. Note that you have to build *and* install the CTF tools first, before building the kernel. Otherwise you can possibly still get error messages similar to "failed to copy type of 'pr_uid': Type information is in parent and unavailable", when attempting to run dtrace(1). Submitted by: kaiw

| | | | | | | | | | | | | GCC can generate bogus dwarf attributes with DW_AT_byte_size set to 0xFFFFFFFF. The issue was originaly detected in NetBSD but it has been adapted for portability and to avoid compiler warnings.

* Make ctfconvert work correctly on clang-compiled object files. Clangdim2013-03-071-0/+3
| | | | | | | | | | | | | puts the full original source filename in the STT_FILE entry of the ELF symbol table, while gcc saves only the basename. Since the DWARF DW_AT_name attribute contains the full source filename, both for clang and gcc, ctfconvert takes just the basename of it, for matching with the STT_FILE entry. So when attempting to match with such an entry, use its basename, if necessary. Reported by: avg MFC after: 1 week
* Maintain target's byte order for multi-byte fields in CTF structures.gonzo2012-03-244-3/+121
| | | | | | | | | | | | | | | | | | | | CTF format is not cross-platform by design, e.g. it is not guaranteed that data generated by ctfconvert/ctfmerge on one architecture will be successfuly read on another. CTF structures are saved/restored using naive approach. Roughly it looks like: write(fd, &ctf_struct, sizeof(ctf_struct)) read(fd, &ctf_struct, sizeof(ctf_struct)) By sheer luck memory layout of all type-related CTF structures is the same on amd64/i386/mips32/mips64. It's different on ARM though. sparc, ia64, powerpc, and powerpc64 were not tested. So in order to get file compatible with dtrace on ARM it should be compiled on ARM. Alternative solution would be to have "signatures" for every platform and ctfmerge should convert host's reperesentation of CTF structure to target's one using "signature" as template. This patch checks byte order of ELF files used for generating CTF record and makes sure that byte order of data written to resulting files is the same as target's byte order.

* Do not encode more than CTF_MAX_VLEN(1023) enum members.kan2010-05-031-1/+8
| | | | | | | | | | | CTF can not represent enums with more than CTF_MAX_VLEN members, but ctfconvert will happily ignore that limitation and create CTF section no other tool can interpret. This change is different from similar change from upstream, which just returns an error if big enum is encountered. Doing that means that every FreeBSD kernel with compiled in hwpmc will have no useable CTF information due to pmc_event enum having 1236+ members.

The changes in this import from the previous import are the ones that will subsequently re-applied to take files off the vendor branch. This is unfortunately necessary because the Solaris developers won't allow FreeBSD support #ifdefs in their source code because that creates 'dead code' (stuff that they never compile).
