Add -mmove-max=bits and -mstore-max=bits to enable 256-bit/512-bit move
and store, independent of -mprefer-vector-width=bits:
1. Add X86_TUNE_AVX512_MOVE_BY_PIECES and X86_TUNE_AVX512_STORE_BY_PIECES
which are enabled for Intel Sapphire Rapids processor.
2. Add -mmove-max=bits to set the maximum number of bits can be moved from
memory to memory efficiently. The default value is derived from
X86_TUNE_AVX512_MOVE_BY_PIECES, X86_TUNE_AVX256_MOVE_BY_PIECES, and the
preferred vector width.
3. Add -mstore-max=bits to set the maximum number of bits can be stored to
memory efficiently. The default value is derived from
X86_TUNE_AVX512_STORE_BY_PIECES, X86_TUNE_AVX256_STORE_BY_PIECES and the

While looking at a proposed vendor backport, I've noticed some
formatting issues in x86-tune.def. Also, in all spots m_GENERIC
comes last, except one recently changed, I think it is useful to have
m_GENERIC always last for consistency.

2. With MOVE_RATIO and CLEAR_RATIO == 17, GCC will use integer/vector
load and store for up to 16 * 16 (256) bytes when the data size is
fixed and known.
3. Inline only if data size is known to be <= 256.
a. Use "rep movsb/stosb" with simple code sequence if the data size
is a constant.
b. Use loop if data size is not a constant.

For TSVC it get used by 5 benchmarks with following runtime improvements:
s4114: 1.424 -> 1.209 (84.9017%)
s4115: 2.021 -> 1.065 (52.6967%)
s4116: 1.549 -> 0.854 (55.1323%)
s4117: 1.386 -> 1.193 (86.075%)
vag: 2.741 -> 1.940 (70.7771%)
there is regression in
s4112: 1.115 -> 1.184 (106.188%)
The internal loop is:
for (int i = 0; i < LEN_1D; i++) {
a[i] += b[ip[i]] * s;
}
(so a standard accmulate and add with indirect addressing)

Looking at instructions latencies
- fmadd is 4 cycles
- vgatherdps is 39
So vgather iself is 4.8 cycle per iteration and probably CPU is able to execute
rest out of order getting clos to 4 cycles per iteration (it can do 2 loads in
parallel, one store and rest fits easily to execution resources). That would
explain 20% slowdown.
gimple internal loop is:
_2 = a[i_38];
_3 = (long unsigned int) i_38;
_4 = _3 * 4;
_5 = ip_18 + _4;
_6 = *_5;
_7 = b[_6];
_8 = _7 * s_19;
_9 = _2 + _8;
a[i_38] = _9;
i_28 = i_38 + 1;
ivtmp_52 = ivtmp_53 - 1;
if (ivtmp_52 != 0)
goto <bb 8>; [98.99%]
else
goto <bb 4>; [1.01%]
0x25bac30 a[i_38] 1 times scalar_load costs 12 in body
0x25bac30 *_5 1 times scalar_load costs 12 in body
0x25bac30 b[_6] 1 times scalar_load costs 12 in body
0x25bac30 _7 * s_19 1 times scalar_stmt costs 12 in body
0x25bac30 _2 + _8 1 times scalar_stmt costs 12 in body
0x25bac30 _9 1 times scalar_store costs 16 in body
so 19 cycles estimate of scalar load
0x2668630 a[i_38] 1 times vector_load costs 12 in body
0x2668630 *_5 1 times unaligned_load (misalign -1) costs 12 in body
0x2668630 b[_6] 8 times scalar_load costs 96 in body
0x2668630 _7 * s_19 1 times scalar_to_vec costs 4 in prologue
0x2668630 _7 * s_19 1 times vector_stmt costs 12 in body
0x2668630 _2 + _8 1 times vector_stmt costs 12 in body
0x2668630 _9 1 times vector_store costs 16 in body
so 40 cycles per 8x vectorized body
tsvc.c:3450:27: note: operating only on full vectors.
tsvc.c:3450:27: note: Cost model analysis:

I think this generally suffers from GIGO principle.
One problem seems to be that we do not know about fmadd yet and compute it as
two instructions (6 cycles instead of 4). More importnat problem is that we do
not account the parallelism at all. I do not see how to disable the
vecotrization here without bumping gather costs noticeably off reality and thus
we probably can try to experiment with this if more similar problems are found.
Icc is also using gather in s1115 and s128.
For s1115 the vectorization does not seem to help and s128 gets slower.
Clang and aocc does not use gathers.

As written in the PR, TARGET_QIMODE_MATH was meant to be set for all
tunings and it was the case for GCC <= 7, but as the number of
PROCESSOR_* enumerators grew, some AMD tunings (which are at the end
of the list) over time got enumerators with values >= 32 and
TARGET_QIMODE_MATH became disabled for them, in GCC 8 for 2
tunings, in GCC 9 for 7 tunings, in GCC 10 for 8 tunings, and
on the trunk for 11 tunings.
The following patch fixes it by using uhwis rather than uints
and gives them also symbolic names.

Currently, __atomic_thread_fence(seq_cst) on x86 and x86-64 generates
mfence instruction. A dummy atomic instruction (a lock-prefixed instruction
or xchg with a memory operand) would provide the same sequential consistency
guarantees while being more efficient on most current CPUs. The mfence
instruction additionally orders non-temporal stores, which is not relevant
for atomic operations and are not ordered by seq_cst atomic operations anyway.

In the r10-7197-gbae7b38cf8a21e068ad5c0bab089dedb78af3346 commit I've
noticed duplicated word in a message, which lead me to grep for those and
we have a tons of them.
I've used
grep -v 'long long\|optab optab\|template template\|double double' *.[chS] */*.[chS] *.def config/*/* 2>/dev/null | grep ' \([a-zA-Z]\+\) \1 '
Note, the command will not detect the doubled words at the start or end of
line or when one of the words is at the end of line and the next one at the
start of another one.
Some of it is fairly obvious, e.g. all the "the the" cases which is
something I've posted and committed patch for already e.g. in 2016,
other cases are often valid, e.g. "that that" seems to look mostly ok to me.
Some cases are quite hard to figure out, I've left out some of them from the
patch (e.g. "and and" in some cases isn't talking about bitwise/logical and
and so looks incorrect, but in other cases it is talking about those
operations).
In most cases the right solution seems to be to remove one of the duplicated
words, but not always.
I think most important are the ones with user visible messages (in the patch
3 of the first 4 hunks), the rest is just comments (and internal
documentation; for that see the doc/tm.texi changes).

The reason for TARGET_SSE_PACKED_SINGLE_INSN_OPTIMAL on AMD target is
only insn size, as advised in e.g. Software Optimization Guide for the
AMD Family 15h Processors [1], section 7.1.2, where it is said:
--quote--
7.1.2 Reduce Instruction SizeOptimization
Reduce the size of instructions when possible.
Rationale
Using smaller instruction sizes improves instruction fetch throughput.
Specific examples include the following:
*In SIMD code, use the single-precision (PS) form of instructions
instead of the double-precision (PD) form. For example, for register
to register moves, MOVAPS achieves the same result as MOVAPD, but uses
one less byte to encode the instruction and has no prefix byte. Other
examples in which single-precision forms can be substituted for
double-precision forms include MOVUPS, MOVNTPS, XORPS, ORPS, ANDPS,
and SHUFPS.
...
--/quote--
Please note that this optimization applies only to non-AVX forms, as
demonstrated by:
0: 0f 28 c8 movaps %xmm0,%xmm1
3: 66 0f 28 c8 movapd %xmm0,%xmm1
7: c5 f8 28 d1 vmovaps %xmm1,%xmm2
b: c5 f9 28 d1 vmovapd %xmm1,%xmm2
Also note that MOVDQA is missing in the above optimization. It is
harmful to substitute MOVDQA with MOVAPS, as it can (and does)
introduce +1 cycle forwarding penalty between FLT (FPA/FPM) and INT
(VALU) FP clusters.

r259399, which added PROCESSOR_SKYLAKE, disabled many x86 optimizations
which are enabled by PROCESSOR_HASWELL. As the result, -mtune=skylake
generates slower codes on Skylake than before. The same also applies
to Cannonlake and Icelak tuning.
This patch changes -mtune={skylake|cannonlake|icelake} to tune like
-mtune=haswell for until their tuning is properly adjusted. It also
enables -mprefer-vector-width=256 for -mtune=haswell, which has no
impact on codegen when AVX512 isn't enabled.

r254152 disabled partial_reg_dependency and movx for Haswell and newer
Intel processors. r258972 restored them for skylake-avx512. For Haswell,
movx improves performance. But partial_reg_stall may be better than
partial_reg_dependency in theory. We will investigate performance impact
of partial_reg_stall vs partial_reg_dependency on Haswell for GCC 9. In
the meantime, this patch restores both partial_reg_dependency and mox for
Haswell in GCC 8.
On Haswell, improvements for EEMBC benchmarks with
-mtune-ctrl=movx,partial_reg_dependency -Ofast -march=haswell
vs
-Ofast -mtune=haswell
are
