information files.
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

M68HC11_LAST_HARD_REG is 8, but m68hc11 register number is started from 0,

VEX.W may be legitimately set (and is then ignored by the CPU) for
non-64-bit code. Don't print 64-bit register names in such a case, by
utilizing that REX_W would never be set for non-64-bit code, and that
it is being set from VEX.W by generic decoding.
A test for this is going to be introduced in the next patch of this
series.
|
|
The low four bits of an immediate being set when the high bits specify a
fourth register operand is not a problem: CPUs ignore these bits rather
than raising #UD. Take care of incrementing codep in OP_EX_VexW()
instead.
|
|
Just like %cxl can't be used as shift count register. Otherwise for
consistency %cxl would need to gain "ShiftCount" and use of both ought
to properly cause REX prefixes to be emitted.

To allow translators to reorder values in translated strings. This
should mean that all binutils messages now have support for
reordering.
Note to translators: Not all % letters take arguments, so for example
the following only has two arguments, the two %s strings.
"%P%F: output format %s cannot represent section called %s: %E\n"
You could reorder this if you liked to:
"%P%F: %E: section %2$s cannot be represented in output format %1$s\n"
einfo lacks support for flags, field width, precision and length
modifier (apart from %ld and %lu) so don't try to use them in
translations. Both ld and bfd lack support to use a positional arg
twice. These features could be added if needed..

We have a customer who is using a Corelis gdb server to connect to gdb.
Occasionally, the gdb server will send a 0-byte block of memory for a
read. When this happens, gdb gives an assertion from target.c:
internal-error: target_xfer_partial: Assertion `*xfered_len > 0' failed.
This problem is almost identical to that fixed in
https://sourceware.org/ml/gdb-patches/2014-02/msg00636.html
In this case, remote.c needs to be modified to return TARGET_XFER_EOF
instead of TARGET_XFER_OK or TARGET_XFER_UNAVAILABLE when 0 bytes are
transferred.

The fix for the PR is to not use input_section->output_section->owner
to get to the output bfd, but use the output bfd directly since it is
available nowadays in struct bfd_link_info.
I thought it worth warning when non-empty dynamic sections are
discarded too, which meant a tweak to one of the ld tests to avoid the
warning.

There is code in bfd/elf-eh-frame.c and ld/emultempl/elf32.em that
checks for the presence of eh_frame info by testing for a section
named .eh_frame sized more than 8 bytes. The size test is to exclude
a zero terminator. A similar check in elf64-ppc.c wrongly just tested
for non-zero size before creating the linker generated .eh_frame
describing plt call and other linkage stubs. The intention was to not
generate that info unless there was some user .eh_frame. (No user
.eh_frame implies the user doesn't care about exception handling.)
Because the test in elf64-ppc.c was wrong, ld generated the stub
.eh_frame just on finding a zero .eh_frame terminator in crtend.o, but
didn't generate the corresponding .eh_frame_hdr.

Commit dd90581873 ("Place .shstrtab section after .symtab and .strtab,

forgot to adjust sh_link references from relocation and group section
table entries.
Additionally some other (perhaps subsequent) change appears to have
added .rel.* and .rela.* sections to their respective groups, which
requires some further adjustments to group-2.d. I assume this additional
breakage wasn't noticed because the test was already failing at that
time.
This makes the gas testsuite complete successfully again for me in a

Linking EFI executables from ELF object files can result in corrupted
COFF section flags if the section's alignment is too high. Issue a
diagnostic in that case, erroring out if this is not a final link, and
make sure only in-range values get written to the output image.
While doing this also make tic80 use the generic alignment macros
instead of custom #ifdef-ary.

... rather than silently dropping it altogether.
i386_finalize_displacement() expects baseindex to already be set, so
the respective statement needs to be moved up. This then also allows a
subsequent conditional to be simplified.
For this to not regress on 32-bit addressing, break out address size
guessing from i386_index_check(), invoking the new function earlier so
that i386_finalize_displacement() has i.prefix[ADDR_PREFIX] available.
i386_addressing_mode () in turn needs i.base_reg / i.index_reg set
earlier.

This patch was aimed at a FIXME in elf32-hppa.c, the ludicrous and
confusing fact that non_got_ref after adjust_dynamic_relocs in that
backend means precisely the inverse of what it means before
adjust_dynamic_relocs. Before, when non_got_ref is set it means there
are dynamic relocs, after, if non_got_ref is clear it means "keep
dynamic relocs" and later, "has dynamic relocs". There is a reason
why it was done that way.. Some symbols that may have dynamic
relocations pre-allocated in check_relocs turn out to not be dynamic,
and then are not seen by the backend adjust_dynamic_symbols. We want
those symbols to lose their dynamic relocs when non-pic, so it's handy
that non_got_ref means the opposite after adjust_dynamic_relocs. But
it's really confusing.
Most other targets, like ppc32, don't always set non_got_ref on
non-GOT references that have dynamic relocations. This is because the
primary purpose of non_got_ref before adjust_dynamic_relocs is to flag
symbols that might need to be copied to .dynbss, and there are
relocation types that may require dyn_relocs but clearly cannot have
symbols copied into .dynbss, for example, TLS relocations.
Why do we need a flag after adjust_dynamic_relocs to say "keep
dynamic relocations"? Well, you can discard most unwanted dyn_relocs
in the backend adjust_dynamic_relocs, and for those symbols that
aren't seen by the backend adjust_dynamic_relocs, in
allocate_dynrelocs based on a flag set by adjust_dynamic relocs,
dynamic_adjusted. That doesn't solve all our difficulties though.
relocate_section needs to know whether a symbol has dyn_relocs, and
many targets transfer dyn_relocs to a weakdef if the symbol has one.
The transfer means relocate_section can't test dyn_relocs itself and
the weakdef field has been overwritten by that time. So non_got_ref
is used to flag "this symbol has dynamic relocations" for
relocate_section.
Confused still? Well, let's hope the comments I've added help clarify
things.. The patch also fixes a case where we might wrongly emit
dynamic relocations in an executable for common and undefined symbols.
* elf32-hppa.c (elf32_hppa_adjust_dynamic_symbol): Set non_got_ref
to keep dyn_relocs, clear to discard. Comment.
(allocate_dynrelocs): Always clear non_got_ref when clearing
dyn_relocs in non-pic case. Invert non_got_ref test. Also test
dynamic_adjusted and ELF_COMMON_DEF_P. Move code deleting
dyn_relocs on undefined syms to handle for non-pic too.
(elf32_hppa_relocate_section): Simplify test for non-pic dyn relocs.
* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Set non_got_ref
to keep dyn_relocs, clear to discard. Comment.
(allocate_dynrelocs): Always clear non_got_ref when clearing
dyn_relocs in non-pic case. Invert non_got_ref test. Also test
dynamic_adjusted and ELF_COMMON_DEF_P. Move code deleting
dyn_relocs on undefined syms to handle for non-pic too.
(ppc_elf_relocate_section): Simplify test for non-pic dyn relocs.
* elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Discard
dyn_relocs here. Don't bother setting non_got_ref. Comment.
(allocate_dynrelocs): Delete special handling of non-pic ELFv2
ifuncs. Move code deleting dyn_relocs on undefined symbols to
handle for non-pic too. Don't test non_got_ref. Do test
dynamic_adjusted and ELF_COMMON_DEF_P.

pass.
