binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the following new arguments: --ctf=SECTION: display CTF in the given SECTION --ctf-parent=SECTION: name of CTF section that is the parent of this section readelf has the above, and these two as well: --ctf-symbols=SECTION: name of symbol table section (optional) --ctf-strings=SECTION: name of string table section (optional) (objdump can always use BFD machinery to determine the applicable string and symbol tables automatically, so these arguments are unnecessary.) Nearly all the work is done by the ctf_dump machinery in libctf: most of the remaining work is option-processing and section-reading, and thus is different for objdump and readelf: the minimal amount of similar code remaining is, in my view, too small to share, particularly given that objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it doesn't have a bfd. I am not particularly satisfied with the way resources are freed in either of these (I was forced to do it at the top level, for lack of anywhere else to free resources allocated during option processing), but I can't see any better way to do it without introducing new infrastructure for no other purpose. There are essentially arbitrary ordering changes to the Makefile.in's order of libtool-related stuff that I can't get rid of, but they have no semantic effect. (It is possible that some hunks of these changes could be dropped, but that seems a bit risky to me.) binutils/ * objdump.c (ctf-api.h): New include. (dump_ctf_section_info): New variable. (dump_ctf_section_name): Likewise. (usage): Describe new options. (enum option_values): Add OPTION_CTF and OPTION_CTF_PARENT. (main): Use them to add --ctf and --ctf-parent.
