GNU_PROPERTY_RISCV_FEATURE_1_CFI_LP_UNLABELED
This patch adds two new GNU properties for RISC-V:
GNU_PROPERTY_RISCV_FEATURE_1_CFI_SS and GNU_PROPERTY_RISCV_FEATURE_1_CFI_LP_UNLABELED.
We only add readelf and define the properties in this patch.

Like ELF for all symbols, COFF can record size for at least function
ones. Use that - if available - in preference to the distance-to-next-
symbol heuristic.
To be able to use the new test there, make TI C54x follow TI C4x in
providing .sdef to cover for .def already having different meaning.
|
|
There's no reason to limit this to just ELF. TI C30 and Z8k don't encode
section alignment in the section entries though (which can't be quite
right, or there would need to be another means by which to express
alignment needs), so --set-section-alignment simply has no effect there.
|
|
PR binutils/32732
The --set-section-alignment option is what ought to be used on object
files; --section-alignment should be affecting PE binaries only, and
only the value stored in the header. Sections don't individually have
alignment recorded there; see 6f8f6017a0c4 ("PR27567, Linking PE files
adds alignment section flags to executables").
Undo the core part of 121a3f4b4f4a ("Update objcopy's
--section-alignment option so that it sets the alignment flag on..."),
which includes removing the testcase again, while leaving all secondary
changes in place. (Note that the testcase did fail anyway for
i?86-interix, with objdump saying "option -P/--private not supported by
this file".)

Compilers may split functions, e.g. into a "hot" and "cold" part, or

ar is supposed to make archives containing any sort of file, and it
generally does that. It also tries to make archives suited to target
object files stored. Some targets have peculiar archives.
In one particular case we get into trouble trying to suit archives to
object files: where the target object file is recognised but that
target doesn't happen to support archives, and the default target has
a special archive format. For example, we'll get failures on
rs6000-aix if trying to add tekhex objects to a new archive. What
happens in that the tekhex object is recognised and its target vector
used to create an empty archive, ie. with _bfd_generic_mkarchive and
_bfd_write_archive_contents. An attempt is then made to open the
newly created archive. The tekhex target vector does not have a
check_format function to recognise generic archives, nor as it happens
do any of the xcoff or other targets built for rs6000-aix.
It seems to me the simplest fix is to not use any target vector to
create archives where that vector can't also recognise them. That's
what this patch does, and to reinforce that I've removed target vector
support for creating empty archives from such targets.

The noxfail option is useful in situations like pr23658-1e which
fails on all microblaze ELF targets except microblaze-linux. This was
possible to handle by writing a small proc and use that as an xfail

this is simpler. The patch also fixes some other FAILs and XPASSes of
the pr23658 tests.

While for executables properly aligning sections within the file can be
quite relevant, the same is of pretty little importance for relocatable
object files. Avoid passing "true" into
_bfd_elf_assign_file_position_for_section() when dealing with object
files, but compensate minimally by applying log_file_align in such
cases as a cap to the alignment put in place.

This patch started life as a relatively simple change to fix some
unimportant objcopy memory leaks, but expanded into a larger patch
when I was annoyed by the awkwardness of passing data when using
bfd_map_over_sections. A simple loop over sections is much more
convenient, and we really don't need the abstraction layer. Sections
in a list isn't going to disappear any time soon.
The patch also removes use of the global "status" variable by all but
the top-level functions called from main.

symcount as a pointer, updated on return.

param with updated smaller section size.

"status" on failure.

(copy_object): Don't use bfd_map_over_sections, instead use a
loop allowing easy detection of failure status. Free memory on
error paths.
(copy_archive): Return bool success rather than setting "status"
on failure.
(copy_file): Set "status" here.
* testsuite/binutils-all/strip-13.d: Adjust to suit.

The logic is same as a71d87680110 ("aarch64: Add DT_RELR support").
As LoongArch does not have -z dynamic-undefined-weak, we don't need to
consider UNDEFWEAK_NO_DYNAMIC_RELOC.
The linker relaxation adds another layer of complexity. When we delete
bytes in a section during relaxation, we need to fix up the offset in
the to-be-packed relative relocations against this section.

Implement a helper to construct a relative path between two locations in
the filesystem, for example to make a path from the source to the object
directory for the case where a tool has been set up to look at a given
path and there is a need to point it elsewhere, but an absolute path
will not work. The helper works on normalized paths internally, so the
result is correct even in the presence of symlinks as intermediate path
components.
So given "/path/to/src/gas/testsuite/gas/all" as the FROM argument and
then "/path/to/obj/gas/testsuite/tmpdir/none.s" as the TO argument the
helper will return "../../../../../obj/gas/testsuite/tmpdir/none.s" in
the absence of symlinks.

Given that the disassembler should never abort when decoding
(potentially random) data, assertion statements in the
`get_*reg_qualifier_from_value' function family prove problematic.
Consider the random 32-bit word W, encoded in a data segment and
encountered on execution of `objdump -D <obj_name>'.
If:
(W & ~opcode_mask) == valid instruction
Then before `print_insn_aarch64_word' has a chance to report the
instruction as potentially undefined, an attempt will be made to have
the qualifiers for the instruction's register operands (if any)
decoded. If the relevant bits do not map onto a valid qualifier for
the matched instruction-like word, an abort will be triggered and the
execution of objdump aborted.
As this scenario is perfectly feasible and, in light of the fact that
objdump must successfully decode all sections of a given object file,
it is not appropriate to assert in this family of functions.
Therefore, we add a new pseudo-qualifier `AARCH64_OPND_QLF_ERR' for
handling invalid qualifier-associated values and re-purpose the
assertion conditions in qualifier-retrieving functions to be the
predicate guarding the returning of the calculated qualifier type.
If the predicate fails, we return this new qualifier and allow the
caller to handle the error as appropriate.
As these functions are called either from within
`aarch64_extract_operand' or `do_special_decoding', both of which are
expected to return non-zero values, it suffices that callers return
zero upon encountering `AARCH64_OPND_QLF_ERR'.
Ar present the error presented in the hypothetical scenario has been
encountered in `get_sreg_qualifier_from_value', but the change is made
to the whole family to keep the interface consistent.

Since ar can be built defaulting to deterministic mode, tests which
expect non-deterministic behaviour need to explicitly set the U flag.
The non-deterministic member test expects SOURCE_DATE_EPOCH to not be

be called on variables which are already set).
