* Process CUs with a language attribute of DW_LANG_Mips_Assembler.Mark Johnston2018-06-111-1/+2
| | | | | | | | | | | At the moment ctfconvert(1) does not do much with such CUs, but that may not be true in the future, and we run ctfconvert on several assembly files during the build. X-MFC with: r334883 Notes: svn path=/head/; revision=334961
* Don't process DWARF generated from non-C/C++ code.Mark Johnston2018-06-091-3/+22
| | | | | | | | | | | | ctfconvert(1) is not designed to handle DWARF generated from such code, and will generally fail in non-obvious ways. Use an explicit check to help catch such potential failures. Reported by: Johannes Lundberg <johalun0@gmail.com> MFC after: 2 weeks Notes: svn path=/head/; revision=334883

* Revert r253678, r253661:Pedro F. Giffuni2016-12-031-40/+2
| | | | | | | | | | | | | | | | Fix a segfault in ctfmerge(1) due to a bug in GCC. The change was correct and the bug real, but upstream didn't adopt it and we want to remain in sync. When/if upstream does something about it we can bring their version. The bug in question was fixed in GCC 4.9 which is now the default in FreeBSD's ports. Our native gcc-4.2, which is still in use in some Tier-2 platforms also has a workaround so no end-user should be harmed by the revert. Notes: svn path=/head/; revision=309490

* Mechanically convert cddl sun #ifdef's to illumosSteven Hartland2015-01-171-2/+2
| | | | | | | | | | | | | | | 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.

* Clang 3.4 will sometimes emit DIE for struct/union member beforeKai Wang2014-01-201-3/+21
| | | | | | | | | | | | | | | | | | emitting the DIE for the type of that member. ctfconvert can not handle this properly and will calculate a wrong member bit offset. Same struct/union type from different .o file will be treated as different types when their member bit offsets are different, and gets added/merged multiple times. This will in turn cause many other structs/pointers/typedefs that refer to the duplicated struct/union gets added/merged multiple times and eventually causes numerous duplicated CTF types in the kernel.debug file. The simple workaround here is to make use of DW_AT_byte_size attribute of the member DIE to calculate the bits occupied by the member's type, without actually resolving the type.
