CORE PT_NOTE segments may have p_align values of 0 or 1. gABI specifies

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.
Tested on i686 and x86-64.

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

readelf.c:decode_arm_unwind has a variable res that is used as a
return value, with FALSE meaning unsuccessful and TRUE meaning

function is successful, if it reaches returning res is still returns
FALSE, resulting eventually in exit status 1 from readelf without any
error message to indicate an error.
This patch fixes the initialization to use TRUE, so avoiding those
spurious errors. I don't have a self-contained test for this issue;
it was observed as many prelink tests failing without the patch and
passing with it.

4. Support for interAptiv MR2 architecture selection for assembly, in
the form of the `-march=interaptiv-mr2' command-line option and its
corresponding `arch=interaptiv-mr2' setting for the `.set' and
`.module' pseudo-ops.
5. Support for interAptiv MR2 architecture selection for disassembly,
in the form of the `mips:interaptiv-mr2' target architecture, for
use e.g. with the `-m' command-line option for `objdump'.

=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.
=== Patch description ===
Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.
Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.

To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:
1. A new ELF ASE flag to mark MIPS16e2 binaries.
2. MIPS16e2 instruction assembly support, including a relaxation update
to use LUI rather than an LI/SLL instruction pair for loading the
high part of 32-bit addresses.
3. MIPS16e2 instruction disassembly support, including updated rules for
extended forms of instructions that are now subdecoded and therefore
do not alias to the original MIPS16 ISA revision instructions even
for encodings that are not valid in the MIPS16e2 instruction set.
Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops. Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.
Parts of this change by Matthew Fortune and Andrew Bennett.

A static, non-relocated global offset table will be embedded in static
binaries produced from objects containing any kind of GOT relocations,
generally PIC code. All symbols will have been resolved in static link
in such binaries making all GOT entries local and their values final as
there is no run-time load processing further performed.
Dump such GOT with `readelf -A' like already done with regular GOT, to
make it easier to examine static code that uses accesses via the GOT
pointer. There will be no dynamic segment or section in a static binary
to get the GOT pointer (DT_PLTGOT) from, so use section headers to find
a `.got' section instead.

The fix for PR binutils/17512 added a check for the dynamic segment being
inside the actual ELF file. If not an error message would be produced:
readelf: Error: the dynamic segment offset + size exceeds the size of the file
Unfortunately for separate debuginfo files it is common for the dynamic
segment not being inside the file because the .dynamic section is NOBITS.
Since the check is done unconditionally in process_program_headers and
process_program_headers is always called (to setup dynamic_addr in case
it is needed). The error is produced on any operations done on any .debug
file (even if no program headers or the dynamic segment is used).
If there are section headers then a cross check is done to see if the
.dynamic section is NOBITS in which case dynamic_addr is set to zero
without a warning or error (which is then checked first before any
operation on the dynamic segement is done).
Move the check for the dynamic segment being inside the actual ELF file
after the cross check with the section headers to suppress the error for
.debug files.

Version definition past end of section
$
The cause is the `if (idx + ent.vd_next <= idx)' condition introduced to
ensure forward progress, which however always triggers for good version
definition section data as the last entry will have its `vd_next' value
set to 0.
Adjust the condition then, to say `if (idx + ent.vd_next < idx)' instead
and to ensure forward progress limit the number of entries processed to
the size of the version definition section, removing the problematic
message from output quoted above, while ensuring the original PR 17531
test case is still handled gracefully.
Add a suitable test case so that we have `readelf --version-info'
coverage; due to the lack of infrastructure needed to run the linker in
the `binutils' test suite and limited justification to implement it add
a new `readelf.exp' script to the `ld' test suite instead, intended to
gather any `readelf' test cases that require the linker to be run. If
ever we decide to have linker infrastructure added to the `binutils'
test suite, then the script can be moved between the test suites.

We've decided to standardize on two flags for RISC-V: "-march" sets the
target architecture (which determines which instructions can be
generated), and "-mabi" sets the target ABI. We needed to rework this
because the old flag set didn't support soft-float or single-float ABIs,
and didn't support an x32-style ABI on RISC-V.
Additionally, we've changed the behavior of the -march flag: it's now a
lot stricter and only parses things we can actually understand.
Additionally, it's now lowercase-only: the rationale is that while the
RISC-V ISA manual specifies that ISA strings are case-insensitive, in
Linux-land things are usually case-sensitive. Since this flag can be
used to determine library paths, we didn't want to bake some
case-insensitivity in there that would case trouble later.
This patch implements these two new flags and removes the old flags that
could conflict with these. There wasn't a RISC-V release before, so we
want to just support a clean flag set.

This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker. I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings. This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

This commit introduces the nps400 machine type as a variant of arc.
There's a new flag in the assembler to select this machine type. All
other changes are just adding handling of the new machine type into the
relevant places.
The nps400 is an arc700 variant with some vendor specific instructions
added into the instruction set. This commit does not add any of the new
instructions, this is just laying the groundwork for future commits.
However, in preparation for these new instructions a new opcode define for
nps400 has been added to include/opcode/arc.h, this new opcode define is
used in the assembler and disassembler along with the existing define
for arc700 such that when assembling and disassembling for nps400 the
user will have access to all arc700 instructions and all the nps400
vendor extension instructions.

The constant EF_ARC_CPU_GENERIC is defined in the include/elf/arc.h
file, and is used in a few places in binutils, however, this constant
should never make it into the elf header flags; we always set a valid
cpu type in the assembler, which should then be copied over during
linking.
There are some non-gnu arc compilers that don't write an architecture
type into the e_flags field, instead leaving the field as 0, which is
the EF_ARC_CPU_GENERIC value. This non-gnu compiler uses the machine
type to distinguish between the old and newer arc architectures, setting
the machine type to EM_ARC_COMPACT for old arc600, arc601, and arc700
architectures, while using EM_ARC_COMPACT2 for newer arcem and archs
architectures.
Previously when displaying the machine flags for an older EM_ARC_COMPACT
machine, if the e_flags had not been filled in, then we relied on the
default case statement to display the message "Generic ARCompact", while
in the EM_ARC_COMPACT2 case we specifically handled EF_ARC_CPU_GENERIC
to print "ARC Generic", leaving the default case to print a message
about unrecognised cpu flag.
After this commit EF_ARC_CPU_GENERIC has been removed, for both machine
types EM_ARC_COMPACT and EM_ARC_COMPACT2 we now rely on the default case
statement to handle the situation where the e_flags has not been filled
in. The message displayed is now "Unknown ARCompact" (for older arc
architectures) and "Unknown ARC" (for the newer architectures). The
switch from "Generic" to "Unknown" in the message string is for clarity,
calling the file "Generic" can give the impression that the file is
compiled for a common sub-set of the architectures, and would therefore
run on any type of machine (or at least any type of new or old machine
depending on if the machine type is ARC or ARCv2). However, this was
not what "Generic" meant, it really meant "Unknown", so that's what we
now say.
As part of the merging of the readelf flag reading code, I have unified
the strings used in displaying the ELF ABI. This means that for older
arc machines (arc600, arc601, and arc700) the string used for the
original ABI, and ABIv2 have changed, the current ABIv3 remains the
same. For the newer architectures (arcem and archs) the abi strings
remain unchanged in all cases.

The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15
include the existing 64-bit wide floating point registers. The Linux
kernel presents the vector registers as two additional register sets,
one for the right halves of v0-v15 and another one for the full
registers v16-v31. Thus a new core file may contain two new register
note sections, and this patch adds support to binutils for them.
