So far z16 was identified as arch14. After the machine has been
announced we can now add the real name.
gas/ChangeLog:

name.
* doc/as.texi: Add z16 and arch14 to CPU string list.

table.
Macro arguments may be separated by commas or just whitespace. Macro
arguments may also be quoted (where one level of quotes is removed in
the course of determining the values for the respective formal
parameters). Furthermore this quote removal knows _two_ somewhat odd
escaping mechanisms: One, apparently in existence forever, is that a
pair of quotes counts as the escaping of a quote, with the pair being
transformed to a single quote in the course of quote removal. The other
(introduced by c06ae4f232) looks more usual on the surface in that it
deals with \" sequences, but it _retains_ the escaping \. Hence only the
former mechanism is suitable when the value to be used by the macro body
is to contain a quote. Yet this results in ambiguity of what "a""b" is
intended to mean; elsewhere (e.g. for .ascii) it represents two
successive string literals. However, in any event is the above different
from "a" "b": I don't think this can be viewed the same as "a""b" when
processing macro arguments.
Change the scrubber to retain such whitespace, by making the processing
of strings more similar to that of symbols. And indeed this appears to
make sense when taking into account that for quite a while gas has been
supporting quoted symbol names.
Taking a more general view, however, the change doesn't go quite far
enough. There are further cases where significant whitespace is removed
by the scrubber. The new testcase enumerates a few in its ".if 0"
section. I'm afraid the only way that I see to deal with this would be
to significantly simplify the scrubber, such that it wouldn't do much
more than collapse sequences of unquoted whitespace into a single blank.
To be honest problems in this area aren't really surprising when seeing
that there's hardly any checking of .macro use throughout the testsuite
(and in particular in the [relatively] generic tests under all/).
This was needed when gas was using the automake cygnus option, but
this was removed years ago by Simon in d0ac1c4488
("Bump to autoconf 2.69 and automake 1.15.1"). So delete it here.

the files whose mode is changed by the script, plus a build with

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit

This patch adds AArch32 support for -march=armv8.[78]-a.
The behaviour of the new options can be expressed using a

The cpu_arch_ver entries are technically redundant but
it seemed less surprising to include them anyway.

This patch adds support for FEAT_MOPS, an Armv8.8-A extension
that provides memcpy and memset acceleration instructions.
I took the perhaps controversial decision to generate the individual
instruction forms using macros rather than list them out individually.
This becomes useful with a follow-on patch to check that code follows
the correct P/M/E sequence.

Format:
.option arch, +<extension><version>, ...
.option arch, -<extension>
.option arch, =<ISA string>
The new direcitve is used to enable/disable extensions for the specific
code region. For example,
.attribute arch, "rv64ic" # arch = rv64i2p0_c2p0
.option push
.option arch, +d2p0, -c # arch = rv64i2p0_f2p0_d2p0, f is added implied
.option arch, =rv32gc # arch = rv32i2p0_m2p0_a2p0_f2p0_d2p0_c2p0
.option pop # arch = rv64i2p0_c2p0
Note that,
1. ".option rvc/norvc" have the same behavior as ".option arch +c/-c".
2. ".option arch -i" is illegal, since we cannot remove base i extension.
3. If arch=rv64i2p0, then ".option arch, +i3p0" will update the i's version
from 2.0 to 3.0.
4. If arch=rv64i3p0, then ".option arch, +i" will update the i's version
from 2.0 to the default one according to the chosen isa spec.

Gas uses the directory part, if present, of the .file 0 directive to set
entry 0 of the directory table in DWARF 5, which represents the "current
directory".
Now Gas also uses the file part of the same directive to set entry 0 of the
file table, which represents the "current compilation file". But the latter
need not be located in the former so GCC will use a full path in the file
part when it is passed a full path:
gcc -c /full/path/test.c -save-temps
yields:
.file 0 "/current/directory" "/full/path/test.c"
in the assembly file and:
The Directory Table (offset 0x22, lines 2, columns 1):
Entry Name
0 (indirect line string, offset: 0x25): /current/directory

The .insn directive can let users use their own instructions, or
some new instruction, which haven't supported in the old binutils.
For example, if users want to use sifive cache instruction, they
cannot just write "cflush.d1.l1" in the assembly code, they should
use ".insn i SYSTEM, 0, x0, x10, -0x40". But the .insn directive
may not easy to use for some cases, and not so friendly to users.
Therefore, I believe most of the users will use ".word 0xfc050073",
to encode the instructions directly, rather than use .insn. But
once we have supported the mapping symbols, the .word directives
are marked as data, so disassembler won't dump them as instructions
as usual. I have discussed this with Kito many times, we all think
extend the .insn direcitve to support the hardcode encoding, is the
easiest way to resolve the problem. Therefore, there are two more
.insn formats are proposed as follows,
(original) .insn <type>, <operand1>, <operand2>, ...
.insn <insn-length>, <value>
.insn <value>
The <type> is string, and the <insn-length> and <value> are constants.

This is to be able to generate data acted upon by AVX512-BF16 and
AMX-BF16 insns. While not part of the IEEE standard, the format is
sufficiently standardized to warrant handling in config/atof-ieee.c.
Arm, where custom handling was implemented, may want to leverage this as
well. To be able to also use the hex forms supported for other floating
point formats, a small addition to the generic hex_float() is needed.
Extend existing x86 testcases.
This is to be able to generate data passed to {,V}CVTPH2PS and acted
upon by AVX512-FP16 insns. To be able to also use the hex forms
supported for other floating point formats, a small addition to the
generic hex_float() is needed.
Extend existing x86 testcases.
The ELF psABI-s are quite clear here: On 32-bit the underlying data type
is 12 bytes long (with 2 bytes of trailing padding), while on 64-bit it
is 16 bytes long (with 6 bytes of padding). Make s_space() capable of
handling 'x' (and 'p') type floating point being other than 12 bytes
wide (also adjusting documentation). This requires duplicating the
definition of X_PRECISION in the target speciifc header; the compiler
would complain if this was out of sync with config/atof-ieee.c.
Note that for now padding space doesn't get separated from actual
storage, which means that things will work correctly only for little-
endian cases, and which also means that by specifying large enough
numbers padding space can be set to non-zero. Since the logic is needed
for a single little-endian architecture only for now, I'm hoping that
this might be acceptable for the time being; otherwise the change will
become more intrusive.
Note also that this brings the emitted data size of .ds.x vs .tfloat in
line for non-ELF targets as well; the issue will be even more obvious
when further taking into account a subsequent patch fixing .dc.x/.dcb.x
(where output sizes currently differ depending on input format).
Extend existing x86 testcases.
Intel AVX512 FP16 instructions use maps 3, 5 and 6. Maps 5 and 6 use 3 bits
in the EVEX.mmm field (0b101, 0b110). Map 5 is for instructions that were FP32
in map 1 (0Fxx). Map 6 is for instructions that were FP32 in map 2 (0F38xx).
There are some exceptions to this rule. Some things in map 1 (0Fxx) with imm8
operands predated our current conventions; those instructions moved to map 3.
FP32 things in map 3 (0F3Axx) found new opcodes in map3 for FP16 because map3
is very sparsely populated. Most of the FP16 instructions share opcodes and
prefix (EVEX.pp) bits with the related FP32 operations.
Intel AVX512 FP16 instructions has new displacements scaling rules, please refer
to the public software developer manual for detail information.

I've been repeatedly confused by, in particular, the .dc.a potable[]
entry being conditional. Grepping in gas/config/ reveals only very few
targets actually #define-ing it. But as of 7be1c4891a the symbol is
always defined, so #ifdef-s are pointless (and, as said, potentially
confusing).
Also adjust documentation to reflect this.
Use the pattern from other projects where we generate the html pages
in a dir named the same as the project. So now we have:
gas/doc/gas.html - single html page
gas/doc/gas/ - multiple html pages
This works for projects that have a doc/ subdir already, but gprof &
ld require a little tweaking since they generate their docs in their
respective toplevels.
This better matches other GNU projects like autoconf/automake where
the html manual is the single page form. We'll support the multi-page
form in a follow up change.
Its (documented) behavior is unhelpful in particular in 64-bit build
environments: While printing large 32-bit numbers in decimal already
isn't very meaningful to most people, this even more so goes for yet
larger 64-bit numbers. bfd_sprintf_vma() still tries to limit the number
of digits printed (without depending on a build system property), but
uniformly produces hex output.
