This patch adds support for the V4 BPF instruction jal/gotol, which is
like ja/goto but it supports a signed 32-bit PC-relative (in number of

operand of the other instruction. This greatly increases the jump

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.
Bring disassembly back in line with what the assembler accepts, thus
also making it self-consistent (with, in particular selector load/store
insns). While there further add D to all affected insns except ARPL
(where S is used, matching LAR/LSL), to also behave correctly in suffix-
always mode.
While there also hook up the Intel variant of the LKGS test.
This patch support Zcb extension, contains new compressed instructions,
some instructions depend on other existed extension, like 'zba', 'zbb'
and 'zmmul'. Zcb also imply Zca extension to enable the compressing
features.

Making target code depend on a host define like _AIX52 is never

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.

Now that we have OP_R(), use it here as well, while wiring memory-only
operands to OP_M() at the same time. To keep the number of consumed
opcode bytes similar to before, make BadOp() also account for VEX/XOP/
EVEX prefix bytes. To keep that change simple, convert need_vex to an
actual count of prefix bytes (keeping intact all prior boolean uses of
the field).
Note how this improves disassembly of such bad encodings, by at least
leaving a hint towards what a "nearby" instruction is. (For KSHIFT*
change the immediates test testcases use, such that disassembly remains
sufficiently in sync.)
While there also use Ux for VPMOV{B,W,D,Q}2M, where decoding through
mod_table[] was missing in the earlier scheme.
Several already use OP_M(), which rejects the register forms of insns,
and a few others can easily be converted to do so as well. (Note that
FXSAVE_Fixup() wires through to OP_M(). Note further that OP_IndirE(),
which wasn't placed very well anyway, is moved down to avoid the need to
forward-declare BadOp().)
Also adjust formatting of and drop PREFIX_OPCODE from a few adjacent
entries.
Masking is not permitted for certain further insns, not falling in any
of the earlier categories. Introduce the Y macro (not expanding to any
output) to flag such cases.
Note that in a few cases entries already covered otherwise are converted
as well, to continue to allow sharing of the string literals.
Masking is not permitted in this case. See the code comment for how this
is being dealt with.
To avoid excess special casing of modes, have OP_M() call OP_E_memory()
directly.
While only zeroing-masking is possible in this case, this still requires
EVEX.z to be clear. Introduce a "global" flag right here, to be re-used
by checks which need to live in specific operand handlers.
Rather than corrupting disassmbly altogether, flag EVEX.z set as bad
when masking isn't in effect in the first place at the time the
destination operand is actually processed.
The code in md_apply_fix which tries to deduce from the operand type
which reloc to apply currently does the wrong thing for absolute
relocs which have been re-written by fixup_segment as pc-relative to
implement a subtraction of a local and an external symbol.
In all these cases we wrongly emit an absolute reloc because we ignore
the fx_pcrel flag in md_apply_fix. However, only for the last one we
actually support a pc relative relocation of the proper size and can
implement it accordingly. For the other 3 we have to issue an error.

Formerly an include of libbfd.h was added in commit 56576f4a72
("LoongArch: gas: Add support for linker relaxation."), in order to
allow calling _bfd_read_unsigned_leb128 from gas, but doing so broke
shared builds. Commit d2fddb6d78 fixed this reference but did not
remove the now unnecessary inclusion of libbfd.h. The gas_assert macro
expands into a conditional call to abort(), but "abort" is re-defined to
_bfd_abort in libbfd.h, so the extra include breaks any gas_assert
usage, and should be removed.
