2019-08-09Add support for a MIPS specific .MIPS.xhash section.Mihailo Stojanovic2-4/+58
This patch is a reimplementation of [1] which was submitted in 2015 by Neil Schellenberger. Copyright issue was sorted out [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (DT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering on the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word (ngnusyms) which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS-specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue as reported in [3], which is caused by the leading word added to the .MIPS.xhash section. Leading word is removed in this patch, and the number of entries in the translation table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is addressed by the corresponding glibc patch). Suggestions on coding style in [4] were taken into account. Existing GNU hash testcase was covered, and another one was added in the MIPS part of the testsuite. The other major change is reserving MIPS ABI version 5 for .MIPS.xhash, marking the need of support for .MIPS.xhash in the dynamic linker (again, addressed in the corresponding glibc patch). This is something which I am not sure of, especially after reading [5]. I am confused on whether this ABI version is reserved for IFUNC, or it can be used for this purpose.

2019-07-23SHF_GNU_MBIND requires ELFOSABI_GNUAlan Modra2-43/+66
When SHF_GNU_MBIND was added in the SHF_LOOS to SHF_HIOS range, it should have required ELFOSABI_GNU since these flags are already in use by other OSes. HPUX SHF_HP_TLS in fact has the same value. That means no place in binutils should test SHF_GNU_MBIND without first checking OSABI, and SHF_GNU_MBIND should not be set without also setting OSABI. At least, that's the ideal, but the patch accepts SHF_GNU_MBIND on ELFOSABI_NONE object files since gas didn't always set OSABI. However, to reinforce the fact that SHF_GNU_MBIND isn't proper without a non-zero OSABI, readelf will display the flag as LOOS+0 if OSABI isn't set. The clash with SHF_HP_TLS means that hppa64-linux either has that flag on .tbss sections or supports GNU_MBIND, not both. (hppa64-linux users, if there are any, may have noticed that GNU ld since 2017 mysteriously aligned their .tbss sections to a 4k boundary. That was one consequence of SHF_HP_TLS being blindly interpreted as SHF_GNU_MBIND.) Since it seems that binutils, gdb, gcc, glibc, and the linux kernel don't care about SHF_HP_TLS I took that flag out of .tbss for hppa64-linux. bfd/ * elf-bfd.h (enum elf_gnu_osabi): Add elf_gnu_osabi_mbind. * elf.c (_bfd_elf_make_section_from_shdr): Set elf_gnu_osabi_mbind.

2019-05-28binutils: CTF support for objdump and readelfNick Alcock10-27/+480
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.

2019-05-21AArch64: Add SVE DWARF registersTamar Christina4-3/+44
The SVE DRAWF register names are missing from binutils, this may cause objdump and readelf to ignore certain DRAWF output as the registers are unknown (most notably CIEs). This patch adds the registers in accordance to the "DWARF for ARM(r) 64-bit Architecture (AARch64) with SVE support" documentation [1]. [1] https://developer.arm.com/docs/100985/latest/dwarf-for-the-arm-64-bit-architecture-aarch64-with-sve-support binutils/ChangeLog: * dwarf.c (dwarf_regnames_aarch64): Add SVE registers. * testsuite/binutils-all/aarch64/sve-dwarf-registers.d: New test. * testsuite/binutils-all/aarch64/sve-dwarf-registers.s: New test.
