1dbade7441 [BFD, LD, AArch64, 3/3] Add --pac-plt to enable PLTs protected with PAC.
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.

1) This patch adds new definitions of PAC enabled PLTs
and both BTI and PAC enabled PLTs.
2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT
for the PAC enabled PLTs.
3) This patch adds a new ld command line option: --pac-plt.
In the presence of this option, the linker uses the PAC
enabled PLTs and marks with DT_AARCH64_PAC_PLT.
4) In case both BTI and PAC are enabled the linker should
pick PLTs enabled with both and also use dynamic tags for both.
All these are made according to the new AArch64 ELF ABI

37c18eedff [BFD, LD, AArch64, 2/3] Add --force-bti to enable BTI and to select BTI enabled PLTs
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.

1) This patch adds a new ld command line option: --force-bti.
In the presence of this option, the linker enables BTI with the
GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning
in case of missing gnu notes for BTI in inputs.
2) It also defines a new set of BTI enabled PLTs. These are used either
when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI
or when the new --force-bti option is used. This required adding new
fields in elf_aarch64_link_hash_table so that we could make the PLT
related information more generic.
3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses
this whenever it picks BTI enabled PLTs.
All these are made according to the new AArch64 ELF ABI

cd702818c6 [BFD, LD, AArch64, 1/3] Add support for GNU PROPERTIES in AArch64 for BTI and PAC
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.

This patch implements the following:
1) This extends in the gnu property support in the linker for
AArch64 by defining backend hooks for elf_backend_setup_gnu_properties,
elf_backend_merge_gnu_properties and elf_backend_parse_gnu_properties.
2) It defines AArch64 specific GNU property
GNU_PROPERTY_AARCH64_FEATURE_1_AND and 2 bit for BTI and PAC in it.
3) It also adds support in readelf.c to read and print these new
GNU properties in AArch64.

7a6e0d89bb Don't use bfd_get_file_size in objdump
Compressed debug sections can have uncompressed sizes that exceed the
original file size, so we can't use bfd_get_file_size.  objdump also
used bfd_get_file_size to limit reloc section size, but I believe the
underlying bug causing the PR22508 out of bounds buffer access was
that we had an integer overflow when calculating the reloc buffer
size.  I've fixed that instead in most of the backends, som and
vms-alpha being the exceptions.  SOM and vmd-alpha have rather more
serious bugs in their slurp_relocs routines that would need fixing
first if we want to fuss about making them safe against fuzzed object
files.

The patch also fixes a number of other potential overflows by using
the bfd_alloc2/malloc2/zalloc2 memory allocation functions.

52d6f3ee94 Testsuite: Allow multiple lines of "as" in testsuite.
Committed on behalf of Matthew Malcomson.

This allows checking the command line parsing more easily than before by
allowing many command line invokations from the same .d file.

Each line is used as a set of flags, and the tests are ran against the output
of the assembler with each set.
Each line of assembler is treated as another set of tests (as if the test file
were copied to another with a different #as: line).

This patch includes some example uses where multiple testcases can be merged
into one file using this new functionality.

46cbf38dc3 binutils: Add new GNU format mode to size utility
The size tool currently defaults to berkeley format output.  However,
this output format has a weird quirk, read-only data is counted
against the text sections, not the data sections.

The code offers no real explanation for why this is, but I'm reluctant
to change it for two reasons, first, I'm assuming it probably makes
sense in some case that I'm not thinking of (maybe a target where
sections are not marked executable, and so there's no distinction
between read-only data and code), and second, the code has been this
way for at least 20 years, I worry that changing things now might
cause more confusion than it solves.

This commit then introduces a new output format for the size tool,
this new format displays the results in a similar manor to the
berkeley format, but counts read-only data in the data column, and
only executable sections are counted in the text column.

Given that this is a brand new output format I've gone ahead and
simplified things a little, while the berkeley format displays the
total twice, once in decimal and once in hex, the new display format
just displays the total in decimal.  Of course, there's still the
'--radix' option which can be used to display all the results in
hexadecimal or octal.

I've called the new format 'gnu', so '--format=gnu' or '-G' are used
to access it.

171b8e1957 run_dump_test source in build directory
Some existing tests build .s and .d files for run_dump_test, using an
absolute #source: line in the .d file.  This patch changes that scheme
a little to instead use "#source: ./..." in .d files rather than
"#source: $objdir/...", which is more useful in cases where the .d
file is not generated.

This allows RX gas test files to be built in the build directory,
rather than in a source directory (which might be read-only).

0a59decbb8 elf: Add PT_GNU_PROPERTY segment type
Linkers group input note sections with the same name into one output
note section with the same name.  One output note section is placed in
one PT_NOTE segment.  New linkers merge all input .note.gnu.property
sections into one output .note.gnu.property section with a single
NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment.  Since older
linkers treat input .note.gnu.property section as a generic note section
and just concatenate all input .note.gnu.property sections into one
output .note.gnu.property section without merging them, we may
see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which
are invalid.

GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such
that linker sets the bit for non-relocatable outputs.  But it isn't
sufficient:

1. It doesn't cover generic properties.
2. When -mx86-used-note=yes is passed to x86 assembler, the
GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED
property in object file and older linkers generate invalid
NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit
set.

I am proposing the following changes:

1. Add PT_GNU_PROPERTY segment type:

 # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553)

which covers .note.gnu.property section.
2. Remove GNU_PROPERTY_X86_UINT32_VALID.
