Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only
relocatable objects which don't contain any instructions, linker
shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging
GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain
GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs.
This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates
readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has
the GNU_PROPERTY_X86_UINT32_VALID bit.

The older linker treats .note.gnu.property section as a generic note

The strip-13 test runs into difficulty using dc.a on some targets.
dc.a writes a power of 2 number of bytes large enough to contain a
target address. On some targets, eg. avr-elf, this can be 2 bytes but
the ELF format used require words of 4 bytes to make up a relocation
entry. There was a hack in the test, duplicating the reloc type into
what is normally the addend to make the test work when little-endian,
but that hack fails for similar big-endian targets.
This patch fixes that problem by arranging to emit 32-bit and 64-bit
ELF relocs using .4byte and .8byte directives, chosen as appropriate
for the ELF size. I've also bumped the reloc number tested to a
higher unused value, and made the number more easily parameterised by
target should that be necessary in the future. Whether REL or RELA
relocs are used is now chosen by a new is_rela readelf test of an
object file, rather than by lists of targets.

This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc.
This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

Binutils documentation uses a mix of spelling for the compound word
"command-line X". According to [1]:
"Sometimes compound words are written separately (nail polish),
sometimes with a hyphen (short-sighted) and sometimes as one word
(eyelashes). Often new compounds are written as two separate words and,
as they become more familiar, they are either connected with a hyphen
(-) or made into one word."
I think command-line X is common enough in our industry that the two
workds command and line should be connected. Since command-line is more
common than commandline, I propose to update binutils documentation to
consistently use "command-line" when this is used as an adjective to a
noun (eg. command-line argument, command-line switch, command-line
option and command-line flag). I've left occurences of "the command
line" as is. I've also left gdb, sim and readline alone and have only
touched public documentation (texi and NEWS files).

This adds a syntax table for dwarf-mode to dwarf-mode.el. I noticed
the need for this when trying to use mark-sexp (C-M-SPC) on a hex

When trying to run the update-gnulib.sh script in gdb, I get this:
Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.
Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22. It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import. And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.
For autoconf, the 2.69 version is universally available, so it's an easy
choice. For automake, different distros and distro versions have
different automake versions. But 1.15.1 seems to be the most readily
available as a package. In any case, it's easy to build it from source.
I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case. They only specify a
lower bound for the acceptable version of automake/autoconf. That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version). In our case, we force people to use a
specific version anyway. For the autoconf version, we have the check in
config/override.m4 that enforces the version we want. It will be one
less thing to update next time we change autotools version.
I hit a few categories of problems that required some changes. They are
described below along with the chosen solutions.
Problem 1:
configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see:
configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
Solution 1:
Adjust the code based on the example at that URL.
Problem 2 (in zlib/):
Makefile.am: error: required file './INSTALL' not found
Makefile.am: 'automake --add-missing' can install 'INSTALL'
Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './AUTHORS' not found
Makefile.am: error: required file './COPYING' not found
Makefile.am: 'automake --add-missing' can install 'COPYING'
Solution 2:
Add the foreign option to AUTOMAKE_OPTIONS.
Problem 3:
doc/Makefile.am:20: error: support for Cygnus-style trees has been removed
Solution 3:
Remove the cygnus options.
Problem 4:
Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
Solution 4:
Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
already defined earlier).
Problem 5:
doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 5:
Rename .texinfo files to .texi.
Problem 6:
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir

doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 6:
Remove the hack at the bottom of doc/Makefile.am and use
the info-in-builddir automake option.
Problem 7:
doc/Makefile.am:35: error: required file '../texinfo.tex' not found
doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex'
Solution 7:
Use the no-texinfo.tex automake option. We also have one in
texinfo/texinfo.tex, not sure if we should point to that, or move it
(or a newer version of it added with automake --add-missing) to
top-level.
Problem 8:
Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
Makefile.am:131: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
Solution 8:
Use subdir-objects, that means adjusting references to some .o that will now
be in config/.
Problem 9:

This patch adds constraints for read and write only system registers with the
msr and mrs instructions. The code will treat having both flags set and none
set as the same. These flags add constraints that must be matched up. e.g. a
system register with a READ only flag set, can only be used with mrs. If The
constraint fails a warning is emitted.
Examples of the warnings generated:
test.s: Assembler messages:
test.s:5: Warning: specified register cannot be written to at operand 1 -- `msr dbgdtrrx_el0,x3'
test.s:7: Warning: specified register cannot be read from at operand 2 -- `mrs x3,dbgdtrtx_el0'
test.s:8: Warning: specified register cannot be written to at operand 1 -- `msr midr_el1,x3'
and disassembly notes:
0000000000000000 <main>:
0: d5130503 msr dbgdtrtx_el0, x3
4: d5130503 msr dbgdtrtx_el0, x3
8: d5330503 mrs x3, dbgdtrrx_el0
c: d5330503 mrs x3, dbgdtrrx_el0
10: d5180003 msr midr_el1, x3 ; note: writing to a read-only register.
Note that because dbgdtrrx_el0 and dbgdtrtx_el0 have the same encoding, during
disassembly the constraints are use to disambiguate between the two. An exact
constraint match is always prefered over partial ones if available.
As always the warnings can be suppressed with -w and also be made errors using
warnings as errors.

This patch adds a new platform option "notes" that can be used to indicate if
disassembly notes should be placed in the disassembly as comments.
These notes can contain information about a failing constraint such as reading
from a write-only register. The disassembly will not be blocked because of this
but -M notes will emit a comment saying that the operation is not allowed.
For assembly this patch adds a new non-fatal status for errors. This is
essentially a warning. The reason for not creating an actual warning type is
that this causes the interaction between the ordering of warnings and errors to
be problematic. Currently the error buffer is almost always filled because of
the way operands are matched during assembly. An earlier template may have put
an error there that would only be displayed if no other template matches or
generates a higher priority error. But by definition a warning is lower
priority than a warning, so the error (which is incorrect if another template
matched) will supersede the warning. By treating warnings as errors and only
later relaxing the severity this relationship keeps working and the existing
reporting infrastructure can be re-used.

Implement a more complex way of selecting targets to include or exclude
with `run_dump_test' cases, by extending the syntax for the `target',
`not-target', `skip' and `not-skip' options (with the binutils and GAS
test suites) and the `target', `alltargets' and `notarget' options (with
the LD test suite) to also accept a name of a TCL procedure instead of a
target triplet glob matching expression. The result, 1 or 0, of the
procedure determines whether the test is to be run or not. This mimics
and expands `dg-require-effective-target' from the GCC test suite.
Names of TCL procedures are supplied in square brackets `[]' as with TCL
procedure calls, observing that target triplet glob matching expressions
do not normally start and end with matching square brackets both at a
time. Arguments for procedures are allowed if required.
Having a way to specify a complex condition for a `run_dump_test' case
to run has the advantage of keeping it local within the test case itself
where tool options related to the check might be also present, removing
the need to wrap `run_dump_test' calls into an `if' block whose only
reason is to do a feature check, and ultimately lets one have the test
reported as UNSUPPORTED automagically if required (not currently
supported by the `run_dump_test' options used for LD).

Fix a typo: `.dc.w' -> `.dc.l' in `strip-13mips64.s', correcting a bug
from commit 2f8ceb3899 ("binutils/testsuite: Support REL and MIPS64
reloc formats with `strip-13'"). For relocation format correctness only
as there is no observable change in test results due to the lack of
connection between the second relocation entry affected and the examined
error message produced.
binutils/
* testsuite/binutils-all/strip-13mips64.s: Use `.dc.l' rather
than `.dc.w' in second relocation.
Avoid false positives and actually verify both that an `unsupported
relocation type 0x8f' message is produced and that no other message is,
except for the final `bad value', in the `strip-13' test. This ensures
that it is a relocation processing error and not a different issue that
has caused `strip' to terminate unsuccessfully, and that the number
representing the unsupported relocation has not been clobbered.
binutils/
* testsuite/binutils-all/strip-13.d: Also expect `unsupported
relocation type 0x8f' error message.
Add source variants for the `strip-13' test that produce relocations in
the REL and MIPS64 formats, fixing a failure for the `mips64el-openbsd'
target. This also corrects output for `i*86-*', `i960-*', `m6812-*' and
`m68hc12-*', o32 `mips*-*', and `score*-*' targets, which however does
not show up as a test result change due to lax error message matching
causing `bad value' previously produced by `strip' as a result of input
file rejection to be accepted as a test pass.
For `m6811-*' aka `m68hc11-*' targets this causes a phantom regression,
because they use 16-bit addressing and therefore `.dc.a' emits 16-bit
quantities causing relocation data constructed in assembly not to be as
expected. Previously input was rejected by `strip' with a `bad value'
message and now it is accepted, however due to the relocation data error
the relocation number is not one of the unsupported ones and the tool
completes successfully, which scores as a test failure.
Disable the test case for `m6811-*' and `m68hc11-*' targets then, as it
is a test case bug rather than a problem with the relevant backend. A
separate change to the test case is required to correct this problem, at
which point the test case can be enabled for the affected targets.

A recent Fedora bug (1520805) exposed a problem with objcopy's reloc
copying code, when a binary also contains mergeable notes. The note
merging code would delete some relocs, but then the reloc copying code
would try to put them back again, which did not work.
So I am checking in the patch below to fix the problem. The patch

When dumping notes, get note alignment from either note section or note

https://sourceware.org/bugzilla/show_bug.cgi?id=22492

CORE PT_NOTE segments may have p_align values of 0 or 1. gABI specifies
that PT_NOTE alignment should be aligned to 4 bytes for 32-bit objects
and to 8 bytes for 64-bit objects. If segment alignment is less than 4,
we use 4 byte alignment.
This reverts commit 650444eb54.
With this patch, running the GDB test case gdb.base/auxv.exp is stuck in
an infinite loop, consuming memory to the point that it renders the
machine unusable. I am reverting it so we can take our time to
investigate while not killing all the developers' machines.
According to gABI, in a note entry, the note name field, not note name
size, is padded for the note descriptor. And the note descriptor field,
not note descriptor size, is padded for the next note entry. Also notes
are aligned to 4 bytes in 32-bit objects and 8 bytes in 64-bit objects.
Since on Linux, .note.ABI-tag and .note.gnu.build-id notes are always
aligned to 4 bytes, we need to use alignment of note section or note
segment, instead of assuming alignment based on ELF file class.

This patch causes problems for glibc linknamespace tests because of how it
changes the output format of readelf on .a files.
Previously, "readelf -W -s libc.a" would produce output starting e.g.:
File: /scratch/jmyers/glibc/many8/build/glibcs/x86_64-linux-gnu/glibc/libc.a(init-first.o)
Symbol table '.symtab' contains 30 entries:
and continuing with symbol information for each object in that .a file.
After this commit, instead it starts:
File: /scratch/jmyers/glibc/many8/build/glibcs/x86_64-linux-gnu/glibc/libc.a
Symbol table '.symtab' contains 30 entries:
and every object's symbol information starts with the same File: line,
missing any information about which object's symbols (within libc.a) are
being listed.
I think the previous File: lines that said libc.a(init-first.o) etc.,
identifying the particular object within libc.a, were clearly preferable,
and the glibc linknamespace tests rely on having that information about
the individual object within libc.a.

Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

Jim has recently started working at SiFive, where he'll be contributing
to our binutils port. Andrew and I would like him to be a maintainer.
My understanding is that this is right place to ask.
I've also changed my address to my SiFive one, where I also work -- it
seems cleaner to have everyone use our proper email address. While I
was in there, I noticed a trailing space after Andrew's name so I went
ahead and removed it as well.

2017-11-07 Palmer Dabbelt <palmer@sifive.com>
* MAINTAINERS (RISC-V): Add Jim Wilson as a maintainer.
Clean up Andrew's entry (remove trailing space, add tabs).
Change Palmer's email address, and clean up entry (add tabs).
binutils has lacked proper pluralization of output messages for a long
time, for example, readelf will display information about a section
that "contains 1 entries" or "There are 1 section headers". Fixing
this properly requires us to use ngettext, because other languages
have different rules to English.
This patch defines macros for ngettext and friends to handle builds
with --disable-nls, and tidies the existing nls support. I've
redefined gettext rather than just defining "_" as dgettext in bfd and
opcodes in case someone wants to use gettext there (which might
conceivably happen with generated code).
