70abf8984b gas: Default to -mrelax-relocations=no on Solaris/x86 [PR19520]
I recently noticed a complex case statement in gas/configure.ac controlling
the setting of ac_default_x86_relax_relocations on Solaris/x86.  Since it
included all versions of Solaris, it could be massively simplified.

Looking closer however, I found that it was introduced in

commit 0cb4071ef9
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Wed Feb 3 08:25:15 2016 -0800

    Add -mrelax-relocations= to x86 assembler

based on PR gas/19520.  This PR reported that the new R_386_GOT32X
etc. relocations weren't supported on older versions of Solaris,
breaking gcc bootstrap.  In response, they were disabled on all Solaris
versions except Solaris 12, where they had been implemented in the
native toolchain based on my findings.

However, Solaris 12 has been rechristened to 11.4 before release,
effectively disabling DEFAULT_GENERATE_X86_RELAX_RELOCATIONS on all
versions of Solaris/x86.

Since Solaris 11.4 cannot be distinguished from earlier versions in
cross configurations, this patch fixes this by removing
--enable-x86-relax-relocations completely, instead disabling
DEFAULT_GENERATE_X86_RELAX_RELOCATIONS in tc-i386.c on Solaris.  It also
adds testcases to verify the -mrelax-relocations default.

Tested on {i386,amd64}-pc-solaris2.11 and {i686,x86_64}-pc-linux-gnu.

97ea2d2514 Remove Solaris/PowerPC support
Solaris/PowerPC was a shortlived Solaris port with limited hardware
support.  It was released with Solaris 2.5.1 back in 1996, with support
removed again only a year later in Solaris 2.6.  Since this is long
obsolete, this patch removes the remains of the support.

Tested by a cross to ppc-unknown-linux-gnu to ascertain the build didn't
get broken.

b0653e3db9 gas: add --enable-default-sframe configure option
SFrames make the most sense when userland as a whole is built with them,
so add a --enable-default-sframe configure flag to facilitate distributors
and vendors doing that.

The primary motivation for a configure-time flag is that we don't support
SFrame for 32-bit x86 but some packaging uses the same flags (with some
added on top) for multilib builds (to support old binaries like games),
and simply adding `-Wa,--gsframe` to the standard build flags isn't an
option (*).

That aside, I believe it'll be helpful for testing and eventual adoption
in any case.

In summary, combined with the recent --gsframe=[yes|no] support (**):
* Configured with --enable-default-sframe and nothing is passed
  => SFrames (previously no SFrames)
* Configured with --enable-default-sframe and --gsframe=yes is passed
  => SFrames (no change from before)
* Configured with --enable-default-sframe and --gsframe=no is passed
  => No SFrames (no change from before)
* Configured with --enable-default-sframe and --gsframe is passed
  => SFrames (no change from before)

* Configured with --disable-default-sframe and nothing is passed
  => No SFrames (no change from before)
* Configured with --disable-default-sframe and --gsframe=yes is passed
  => SFrames (no change from before)
* Configured with --disable-default-sframe and --gsframe=no is passed
  => No SFrames (no change from before)
* Configured with --disable-default-sframe and --gsframe is passed
  => SFrames (no change from before)

I've introduced a sframe_as_bad macro on Indu's suggestion. A following
patch uses its sibling sframe_as_warn heavily and having symmetry plus
the macro as a form of documentation of intent seems useful.

(*) It gets added to multilib builds too and then we hit the
    `.sframe not supported for target` error in gas/dw2gencfi.c.

(**) I've verbosely listed --gsframe=yes but it's the same as --gsframe.

83eab1060d MIPS/GAS: Fix comment about "img" vendor configurations

9371764e93 MIPS/GAS: Set default CPU to MIPS64r6 for 64-bit "img" configurations
Fix broken commit 070961b377 ("MIPS: Set r6 as default arch if vendor
is img") that sets up GAS in an inconsistent way where "img" vendor has
been used with a 64-bit configuration, such as `mips64-img-linux-gnu'.
In that case GAS is set up to use a 64-bit ABI by default combined with
the MIPS32r6 CPU, which is 32-bit.

Consequently GAS always fails to assemble even trivial input, producing
a message such as:

Assembler messages:
Error: -march=mips32r6 is not compatible with the selected ABI
.../gas/testsuite/gas/all/nop.s:2: Error: `gp=32' used with a 64-bit ABI

unless the defaults have been suitably overridden either for the ABI or
the CPU.

Set the default CPU to MIPS64r6 for 64-bit "img" vendor configurations
then and adjust the GAS testsuite accordingly, removing 1048 FAIL and 3
ERROR regression test results for the `mips64-img-linux-gnu' and
`mips64el-img-linux-gnu' targets each.

46f44aa700 x86: drop largely defunct gas emulations
Both ELF and COFF have various sub-flavors, each of which would then
require its own emulation: Right now when configuring a COFF/PE
secondary target (with perhaps an ELF primary one), one gets plain COFF
emulation rather than COFF/PE one.

As such a multitude of emulations would be unwieldy (and likely fragile)
drop gas emulations altogether instead.

d774bf9b36 x86: Add tls check in gas
Assembler shouldn't accept invalid TLS instructions, TLS relocations
can only be used with specific instructions as specified in TLS psABI
and linker issues an error when TLS relocations are used with wrong
instructions or format. Since it is inconvenient for gcc to rely on
linker to report errors, adding TLS check in the assembler stage so
that gcc can know TLS errors earlier.

f3d38d7d0b arc: Update ARC's Gnu Assembler backend with ARCv3 ISA.
The new Synopsys ARCv3 ISA has a similar instruction format like
the old ARCv1 and ARCv2 ISA.  Thus, the ARCv3 addition is using
whatever we have for old ARC processors plus some ARCv3 spcific mods.

To distinguish between various ARC variants, we introduced two new
configure defines named TARGET_ARCv3_32 and TARGET_ARCv3_64 which are
set when we choose either an ARC32 (ARCv3/32) ISA toolchain or an
ARC64 (ARCv3/64) ISA toolchain.

29c108c961 MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets
Make the n64 ABI the default for 64-bit Linux targets specified with
`-gnuabi64' suffix included in the target triplet, for configurations
such as the Debian mips64el and mips64r6el ports.  Adjust testsuite
configuration accordingly.

There are the following regressions with the new target triplet:

mips64-linux-gnuabi64  +FAIL: readelf -S bintest
mips64-linux-gnuabi64  +FAIL: MIPS reloc estimation 1
mips64el-linux-gnuabi64  +FAIL: readelf -S bintest
mips64el-linux-gnuabi64  +FAIL: MIPS reloc estimation 1

The `readelf' issue comes from a difference in section headers produced
that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template
does not match.  While there has been a precedent it does not appear to
me that there is a clear advantage from adding more and more variations
to the template rather than forking the existing template into multiple
ones for a more exact match.  So this is best deferred to a separate
discussion.

The MIPS reloc estimation issue is an actual bug in `objdump', which
discards a number of trailing entries from output here for n64 composed
relocations:

DYNAMIC RELOCATION RECORDS
OFFSET           TYPE              VALUE
0000000000000000 R_MIPS_NONE       *ABS*
0000000000000000 R_MIPS_NONE       *ABS*

and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not
match even though ELF output produced is correct according to `readelf':

Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries:
  Offset          Info           Type           Sym. Value    Sym. Name
000000000000  000000000000 R_MIPS_NONE
                    Type2: R_MIPS_NONE
                    Type3: R_MIPS_NONE
000000010000  000300001203 R_MIPS_REL32      0000000000010010 foo@@V2
                    Type2: R_MIPS_64
                    Type3: R_MIPS_NONE

As a genuine bug this has to be handled separately.

d218e7fedc DesCGENization of the BPF binutils port
CGEN is cool, but the BPF architecture is simply too bizarre for it.

The weird way of BPF to handle endianness in instruction encoding, the
weird C-like alternative assembly syntax, the weird abuse of
multi-byte (or infra-byte) instruction fields as opcodes, the unusual
presence of opcodes beyond the first 32-bits of some instructions, are
all examples of what makes it a PITA to continue using CGEN for this
port.  The bpf.cpu file is becoming so complex and so nested with
p-macros that it is very difficult to read, and quite challenging to
update.  Also, every time we are forced to change something in CGEN to
accommodate BPF requirements (which is often) we have to do extensive
testing to make sure we do not break any other target using CGEN.

This is getting un-maintenable.

So I have decided to bite the bullet and revamp/rewrite the port so it
no longer uses CGEN.  Overall, this involved:

* To remove the cpu/bpf.{cpu,opc} descriptions.

* To remove the CGEN generated files.

* To replace the CGEN generated opcodes table with a new hand-written
  opcodes table for BPF.

* To replace the CGEN generated disassembler wih a new disassembler
  that uses the new opcodes.

* To replace the CGEN generated assembler with a new assembler that uses the
  new opcodes.

* To replace the CGEN generated simulator with a new simulator that uses the
  new opcodes. [This is pushed in GDB in another patch.]

* To adapt the build systems to the new situation.

Additionally, this patch introduces some extensions and improvements:

* A new BPF relocation BPF_RELOC_BPF_DISP16 plus corresponding ELF
  relocation R_BPF_GNU_64_16 are added to the BPF BFD port.  These
  relocations are used for section-relative 16-bit offsets used in
  load/store instructions.

* The disassembler now has support for the "pseudo-c" assembly syntax of
  BPF.  What dialect to use when disassembling is controlled by a command
  line option.

* The disassembler now has support for dumping instruction immediates in
  either octal, hexadecimal or decimal.  The used output base is controlled
  by a new command-line option.

* The GAS BPF test suite has been re-structured and expanded in order to
  test the disassembler pseudoc syntax support.  Minor bugs have been also
  fixed there.  The assembler generic tests that were disabled for bpf-*-*
  targets due to the previous implementation of pseudoc syntax are now
  re-enabled.  Additional tests have been added to test the new features of
  the assembler.  .dump files are no longer used.

* The linker BPF test suite has been adapted to the command line options
  used by the new disassembler.

The result is very satisfactory.  This patchs adds 3448 lines of code
and removes 10542 lines of code.

Tested in:

* Target bpf-unknown-none with 64-bit little-endian host and 32-bit
  little-endian host.

* Target x86-64-linux-gnu with --enable-targets=all

Note that I have not tested in a big-endian host yet.  I will do so
once this lands upstream so I can use the GCC compiler farm.

I have not included ChangeLog entries in this patch: these would be
massive and not very useful, considering this is pretty much a rewrite
of the port.  I beg the indulgence of the global maintainers.

478409b71d AIX_WEAK_SUPPORT
Making target code depend on a host define like _AIX52 is never
correct, so out it goes.  Also, sort some config.bfd entries a little
to make it more obvious there is a config difference between aix5.1
and aix5.2.  These two changes should make no difference to anything
in binutils.  The gas define of AIX_WEAK_SUPPORT on the other hand was
wrong, so fix that.  Finally, fix some testsuite fails on aix < 5.2 by
simply not running the tests.

include/
	* coff/internal.h (C_WEAKEXT): Don't depend on _AIX52.

be0d391f22 MIPS: default r6 if vendor is img
This behavior is used by downstream toolchain since 2014.
We also set the default ABI for mips*-img-elf to O32.
The previous value is NO_ABI, which is not good default ABI.

We don't support mips64*-img* due to GCC doesn't support it,
and We believe that the multilib should be used for this case.

32f1c80375 MIPS: support mips*64 as CPU and gnuabi64 as ABI
For MIPS64r6 ports, Debian as an example, `mipsisa64r6el` is
used as the cpu name in triple.
Let's recognize them by `mips*64*(el)`.

For 64bit Ports, like Debian's mips64el and mips64r6el ports,
`gnuabi64` is used as the abi section.
Let's use N64 abi by default for the triple with gnuabi64.

2cac01e3ff binutils, gdb: support zstd compressed debug sections
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.

```

aa0587b290 RISC-V: Enable elf attributes when default configure option isn't set.
Since gcc commit, 3c70b3ca1ef58f302bf8c16d9e7c7bb8626408bf, we now enable
elf attributes for all riscv targets by default in gcc.  Therefore, I
think binutils should have the same behavior, in case users are writing
assembly files.  If --enable-default-riscv-attribute isn't set, then we
enable the elf attributes for all riscv targets by default.
