The Nios II architecture has been EOL'ed by the vendor. This patch
removes all binutils, bfd, gas, binutils, and opcodes support for this
target with the exception of the readelf utility. (The ELF EM_*
number remains valid and the relocation definitions from the Nios II
ABI will never change in future, so retaining the readelf support
seems consistent with its purpose as a utility that tries to parse the
headers in any ELF file provided as an argument regardless of target.)

This reverts commit e874cbd3879843a83e4bcc4b54cd7107387b1df6.
The patch was wrong. LIBINTL_DEP is needed with an in-tree gettext.
|
|
The intl directory in the source no longer exists. LIBINTL_DEP is
thus always empty. Remove references to it.

The new Synopsys's ARCv3 ISA is capable to run either 64-bit or
32-bit ISA. The new 32-bit ISA is not compatible with the old
Synopsys ARCv1/ARCv2 ISA, however, it retains a lot of common
concepts. Thus, this patch is reusing the old ARC BFD backend and
adds the necessary bits for the new architecture in a similar way as
it is done for RISCV backend.

* use power-of-two hash table
* use better hash function (hashing 32bits at once and with better
mixing characteristics)
* use input-offset-to-entry maps instead of retaining full input
contents for lookup time
* don't reread SEC_MERGE section multiple times
* care for cache behaviour for the hot lookup routine
The overall effect is less usage in libz and much faster string merging
itself. On a debug-info-enabled cc1 the effect at the time of this
writing on the machine I used was going from 14400 perf samples to 9300
perf samples or from 3.7 seconds to 2.4 seconds, i.e. about 33% .

The linker merges all the input .sframe sections. When merging, the
linker verifies that all the input .sframe sections have the same
abi/arch.
The linker uses libsframe library to perform key actions on the
.sframe sections - decode, read, and create output data. This
implies buildsystem changes to make and install libsframe before
libbfd.
The linker places the output .sframe section in a new segment of its
own: PT_GNU_SFRAME. A new segment is not added, however, if the
generated .sframe section is empty.
When a section is discarded from the final link, the corresponding
entries in the .sframe section for those functions are also deleted.
The linker sorts the SFrame FDEs on start address by default and sets
the SFRAME_F_FDE_SORTED flag in the .sframe section.
This patch also adds support for generation of SFrame unwind
information for the .plt* sections on x86_64. SFrame unwind info is
generated for IBT enabled PLT, lazy/non-lazy PLT.
The existing linker option --no-ld-generated-unwind-info has been
adapted to include the control of whether .sframe unwind information
will be generated for the linker generated sections like PLT.
Changes to the linker script have been made as necessary.

gas uses ZSTD_compressStream2 which is only available with libzstd >=
1.4.0, leading to build errors when an older version is installed.
This patch updates the check libzstd presence to check its version is
>= 1.4.0. However, since gas seems to be the only component requiring
such a recent version this may imply that we disable ZSTD support for
all components although some would still benefit from an older
version.
I ran 'autoreconf -f' in all directories containing a configure.ac
file, using vanilla autoconf-2.69 and automake-1.15.1. I noticed
several errors from autoheader in readline, as well as warnings in
intl, but they are unrelated to this patch.
This should fix some of the buildbots.
OK for trunk?
Thanks,
Christophe

aarch64-pe support for LD, GAS and BFD
It appears that bfd/Makefile.in and bfd/configure were not regenerated
correctly. The differences in the configure file are only whitespace,
but in Makefile.in a critical reference to pe-aarch64.lo was missing.

Allows aarch64-pe to be targeted natively, not having to use objcopy to convert it from ELF to PE.

PR29397 PR29563: Add new configure option --with-zstd which defaults to
auto. If pkgconfig/libzstd.pc is found, define HAVE_ZSTD and support
zstd compressed debug sections for most tools.
* bfd: for addr2line, objdump --dwarf, gdb, etc
* gas: support --compress-debug-sections=zstd
* ld: support ELFCOMPRESS_ZSTD input and --compress-debug-sections=zstd
* objcopy: support ELFCOMPRESS_ZSTD input for
--decompress-debug-sections and --compress-debug-sections=zstd
* gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd
symbols, so gdb has to link against -lzstd in this patch.
If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We
can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this
is too heavyweight, so don't do it for now.
```

Some components of GNU Binutils will pass "-Wstack-usage=262144" when
"GCC >= 5.0" is detected. However, Clang does not support "-Wstack-usage",
despite that related configuration part in bfd/warning.m4 handles the latest
Clang (15.0.0 as of this writing) as "GCC >= 5.0".
The option "-Wstack-usage" was ignored when the first version of Clang is
released but even this "ignoring" behavior is removed before Clang 4.0.0.
So, if we give Clang "-Wstack-usage=262144", it generates a warning, making
the build failure.
This commit checks "__clang__" macro to prevent adding the option if the
compiler is identified as Clang.

This means that this target does not support relocation processing and is mostly
a container format. This format has been added to elf based loongarch64 targets
such that efi images can be made natively on Linux.
However this target is not valid for use with gas but only with objcopy.
We should't limit addresses to 32-bits for 64-bit vma, otherwise there will be
"RVA truncated" error when using objcopy on loongarch64.
With these changes the resulting file is recognized as an efi image.
Any magic number is based on the Microsoft PE specification [1].
The test results are as follows:
$ make check-binutils RUNTESTFLAGS='loongarch64.exp'
PASS: Check if efi app format is recognized
$ objdump -h -f tmpdir/loongarch64copy.o

There is a problem with my commit 0e3c1eebb2, which replaced
bfd_uint64_t with uint64_t: Some hosts typedef int64_t to long long
even when long is the same size as long long. That confuses the code
choosing one of "l", "ll", or "I64" for BFD_VMA_FMT, and results in
warnings.
Write a direct configure test for the printf int64_t style instead.
This removes the last use of BFD_HOST_64BIT_LONG, so delete that.
Note that the changes to configure.com are pure guesswork.

Commit 04f096fb9e25 ("Move the xc16x target to the obsolete list") moved
the architecture from the "obsolete but still available" to the
"obsolete / support removed" list in config.bfd, making the architecture
impossible to enable (except maybe via "enable everything" options").
Note that I didn't touch */po/*.po{,t} on the assumption that these
would be updated by some (half)automatic means.

bfd_hostptr_t is defined as a type large enough to hold either a long
or a pointer. It mostly appears in the coff backend code in casts.
include/coff/internal.h struct internal_syment and union
internal_auxent have the only uses in data structures, where
comparison with include/coff/external.h and other code reveals that
the type only needs to be large enough for a 32-bit integer or a
pointer. That should mean replacing with uintptr_t is OK.

This patch removes the definition of bfd_uint64_t and bfd_int64_t as
well as most BFD_HOST_* which are now unused.

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".
Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).
Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.
NM=my-nm now does a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM=/usr/bin/my-nm now avoids a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM="my-nm -p../wombat" now does a path search and runs e.g.
/usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)
Regenerate all affected configure scripts.
* libtool.m4 (LT_PATH_NM): Handle user-specified NM with
options, including options containing paths.

Add support for the AMDGCN architecture to BFD.
This is the bare minimum to get
$ ./configure --target=amdgcn-hsa-amdhsa --disable-gas
$ make all-binutils
working later in this series.
The specific AMDGCN models added here are a bit arbitrary, based on
what we intend to initially support in GDB. This list will need to be
updated in the future anyway. The complete up-to-date list of existing
AMDGPU models can be found here:
https://llvm.org/docs/AMDGPUUsage.html#processors
The ELF format for this architecture is documented here:
https://llvm.org/docs/AMDGPUUsage.html#elf-code-object
The flags for the "HSA" OS ABI are properly versioned and documented on
that page. But the NONE, PAL and MESA3D OS ABIs are not well documented
nor versioned. Taking a peek at the LLVM source code, we see that they
encode their flags the same way as HSA v3. For example, for PAL:
https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601
So at least, we know that all AMDGPU objects (of which AMDGCN objects
are a subset of) at the time of writing encode the specific GPU model in
the EF_AMDGPU_MACH field of e_flags.

regenerate files.

Move the 64-bit bfd logic out of bfd/configure.ac and into bfd64.m4
under config so it can be shared between all the other subdirs.
This replaces want64 with enable_64_bit_bfd which was already being
declared, but not used directly.
