--- Comment #3 from Oleg Endo  ---
In your attached libcanberra_la-read-vorbis.s I can spot the following
suspicious code:


.LBB70:
.loc 1 44 9 is_stmt 0
mova.L52,r0
.LVL48:
mov.b   @(r0,r2),r1
extu.b  r1,r1
.LVL49:
brafr1
nop

.

.L82:
.long   ca_vorbis_get_nchannels@PLT-(.LPCS10+2-.)
.L86:
.long   free@PLT-(.LPCS9+2-.)
.L87:
.long   ov_clear@PLT-(.LPCS11+2-.)
.align 2
.L52:
.byte   .L54-.L53
.byte   .L54-.L53
.byte   .L51-.L53
.align 1  (1)
.L54:
.LBE70:
.LBE72:   (2)
.loc 1 61 24
bra .L50
mov #-7,r9


In (1) a lookup table of 3 bytes is emitted.  Because of the following ".align
1" directive, the following code at (2) will be misaligned.

Can you please try to compile with -fverbose-asm  maybe it will give a
first hint as to where the problematic code comes from.

Even though unsigned might be the cheaper check, you might need to swap the
order back to where it was so you check integral first.

Otherwise this is nice cleanup. (Note I can't approve it though).

Thanks,

[PATCH v1] Match: Extract integer_types_ternary_match helper to avoid code dup [NFC]

[pan2 . li]

From: Pan Li 

There are sorts of match pattern for SAT related cases,  there will be
some duplicated code to check the dest, op_0, op_1 are same tree types.
Aka ternary tree type matches.  Thus, extract one helper function to
do this and avoid match code duplication.

The below test suites are passed for this patch:
* The rv64gcv fully regression test.
* The x86 bootstrap test.
* The x86 regression test.

gcc/ChangeLog:

* generic-match-head.cc (integer_types_ternary_match): New helper
function to check tenary tree type matches or not.
* gimple-match-head.cc (integer_types_ternary_match): Ditto but
for match.
* match.pd: Leverage above helper function to avoid code dup.

[to-be-committed][RISC-V][PR target/115142] Do not create invalidate shift-add insn

[Jeff Law]

Repost, this time with the RISC-V tag so it's picked up by the CI system.

This fixes a minor bug that showed up in the CI system, presumably with 
fuzz testing.


Under the right circumstances, we could end trying to emit a shift-add 
style sequence where the to-be-shifted operand was not a register.  This 
naturally leads to an unrecognized insn.


The circumstances which triggered this weren't something that should 
appear in the wild (-ftree-ter, without optimization enabled).  So I 
wasn't planning to backport.  Obviously if it shows up in another 
context we can revisit that decision.


PR target/115142
gcc/

* config/riscv/riscv.cc (mem_shadd_or_shadd_rtx_p): Make sure
shifted argument is a register.

gcc/testsuite

* gcc.target/riscv/pr115142.c: New test.

I've run this through my rv32gcv and rv64gc tester.  Waiting on the CI 
system before committing.

--- Comment #3 from Andrew Pinski  ---
I wonder if my r13-7434-g682bbd364708fe exposed the issue.
And then r14-3432-gddd64a6ec3b38e "fixed" it (on accident).

It was caused by something that was backported to GCC 13 for GCC 13.2.0 too.
It works in GCC 14.1.0 and the trunk for me.

This is fixed in GCC 14. I think it was one of my match.pd patches and it might
be backported already to the GCC 13 branch. Let me look.

--- Comment #1 from Hans-Peter Nilsson  ---
I also ran a round compiled with -fno-ivopts -fno-delayed-branch: the latter
because it's somewhat non-linear in finding delay-slot-filling opportunities
(lack of "luck" causing improvements to negate) and the former because it was
mentioned in the commit as similarly messing things up.

That "fixed" all of the performance drop for random_bitstring, but still left
an almost-as-large performance drop in main in
gcc.c-torture/execute/arith-rand-ll.c. IOW, the net performance drop is 1.25%:

r15-0517:
Basic clock cycles, total @: 13662157

r15-0518:
Basic clock cycles, total @: 13832953

The focus of this bug was the on subset of arith-rand-ll.c that is in
gcc.target/cris/pr93372-47.c (i.e. no main function), so if I keep that, the
gist of this PR should instead shift to something like 50% "r15-518 doesn't
play nice with ivopts" but I guess that's already known.

So if anyone's interested in improving r15-518 (but not in ivopts interaction),
I'd suggest that'd be in what happens in the main function for
gcc.c-torture/execute/arith-rand-ll.c.

Having said that, I did compile gcc.target/cris/pr93372-47.c adding -fno-ivopts
-fdump-tree-optimized and it shows that the tot_bits computation ("tot_bits_13
= tot_bits_8 + n_bits_12;") is moved later, right before it's used in a
conditional, which makes me think the delay-branch-scheduling has less
"material" to fill the first delays-slots.

I also compiled gcc.c-torture/execute/arith-rand-ll.c with -fno-ivopts
-fdump-tree-optimized (plus the usual -O2 -march=v10) and will attach the
tree-dump files.  They show what the pr93372-47.c change *and* that several
division operations are moved forward.  This separates them from the modulus
opterations on the same values, so I guess targets where computing these values
together is a win (not CRIS), we'll see a performance loss.

I'm confused about the tests added here:

> enum H { x = 1 };
> enum H { x = 2UL + UINT_MAX };
Shouldn't this be a constraint violation if unsigned long is wide than
unsigned?

> If two declarations of the same type have a member-declaration or

Section 6.7.3.4 "Tags" Paragraph 1 N3220

I don't see anything that would require a conversion to int here, nor would I
expect this to be the intent. It should just have the same value and the type
will end up the same as in the previous declaration.

> enum E { a = 1L, b = 2 };
> enum E { a = 1L, b = _Generic(a, enum E: 2) }; /* { dg-warning "outside the 
> range" } */
This just seems to be testing if int is compatible with enum E. Which from
testing on godbolt is false on GCC since it would pick for enum E to be
compatible with unsigned. This test also doesn't seem related to the problem
which was having the types of the integral constant expressions for a be
different types.

Subject: [PATCH] Add widening expansion of MULT_HIGHPART_EXPR for integral modes

Hi,

for integral modes, the expansion of MULT_HIGHPART_EXPR requires the presence 
of an {s,u}mul_highpart optab whereas, for vector modes, widening expansion is
supported.  This adds a widening expansion for integral modes too, which is in 
fact already implemented in expmed_mult_highpart_optab.  We'll use that in a 
subsequent change to the Ada front-end to generate fast modulo reduction for 
modular types with nonbinary modulus (a little controversial Ada 95 feature).

Tested on x86-64/Linux, OK for the mainline?

2024-04-29  Eric Botcazou  

* expmed.h (expmed_mult_highpart_optab): Declare.
* expmed.cc (expmed_mult_highpart_optab): Remove static keyword.
Do not assume that OP1 is a constant integer.  Fix pasto.
(expmed_mult_highpart): Pass OP1 narrowed to MODE in all the calls
to expmed_mult_highpart_optab.
* optabs-query.cc (can_mult_highpart_p): Use 2 for integer widening
and shift subsequent values accordingly.
* optabs.cc (expand_mult_highpart): Call expmed_mult_highpart_optab
when can_mult_highpart_p returns 2 and adjust to above change.

--- Comment #6 from Andrew Pinski  ---
I suspect r14-4365-g0731889c026bfe is the cause.

```
 (define_insn "arm_atomic_loaddi2_ldrd"
   [(set (match_operand:DI 0 "register_operand" "=r")
(unspec_volatile:DI
- [(match_operand:DI 1 "arm_sync_memory_operand" "Q")]
+ [(match_operand:DI 1 "memory_operand" "m")]
VUNSPEC_LDRD_ATOMIC))]
   "ARM_DOUBLEWORD_ALIGN && TARGET_HAVE_LPAE"
-  "ldrd%?\t%0, %H0, %C1"
-  [(set_attr "predicable" "yes")])
+  "ldrd\t%0, %H0, %1"
+)
```

Most likely that should have been `ldrd_strd_offset_operand/Do` . There might
be other places in that patch which made the same mistake too.

We have also see the same failure building kodi (vpeter4 did the investigation) 
The difference between gcc13 and 14 is

gcc-13, ok
add r0, r0, #384
ldrdr2, r3, [r0]

gcc-14, not ok
dmb ish
ldrdr2, r3, [r0, #384]

[PATCH] PHIOPT: Don't transform minmax if middle bb contains a phi [PR115143]

[Andrew Pinski]

The problem here is even if last_and_only_stmt returns a statement,
the bb might still contain a phi node which defines a ssa name
which is used in that statement so we need to add a check to make sure
that the phi nodes are empty for the middle bbs in both the
`CMP?MINMAX:MINMAX` case and the `CMP?MINMAX:B` cases.

OK for trunk and backport to all open branches since r14-3827-g30e6ee074588ba 
was backported?
Bootstrapped and tested on x86_64_linux-gnu with no regressions.

phi nodes for middle bbs for the case where middle bb is not empty.

[to-be-committed][PR target/115142] Do not create invalidate shift-add insn

[Jeff Law]

This fixes a minor bug that showed up in the CI system, presumably with 
fuzz testing.


Under the right circumstances, we could end trying to emit a shift-add 
style sequence where the to-be-shifted operand was not a register.  This 
naturally leads to an unrecognized insn.


The circumstances which triggered this weren't something that should 
appear in the wild (-ftree-ter, without optimization enabled).  So I 
wasn't planning to backport.  Obviously if it shows up in another 
context we can revisit that decision.


PR target/115142
gcc/

* config/riscv/riscv.cc (mem_shadd_or_shadd_rtx_p): Make sure
shifted argument is a register.

gcc/testsuite

* gcc.target/riscv/pr115142.c: New test.

I've run this through my rv32gcv and rv64gc tester.  Waiting on the CI 
system before committing.

That is it looks like a bad interaction between `Vector(1) char` stores and
reads from char. BUT I don't understand how it gets that badly wrong.

Note using "/tmp/rsp.txt" is not acceptable at all since there might be a few
linking happening on the machine. You should use make_at_file (which will make
either a tmp file which will be deleted at the end compiling or an .args.N file
which can be looked at if used with -save-temps) instead from gcc.cc and then
pass the filename to collect2 as "@filename" and then inside collect2 expand as
needed.

[gcc r15-647] RISC-V: Implement -m{,no}fence-tso

[Jeff Law via Gcc-cvs]

https://gcc.gnu.org/g:a6114c2a691112f9cf5b072c21685d2e43c76d81

commit r15-647-ga6114c2a691112f9cf5b072c21685d2e43c76d81
Author: Palmer Dabbelt

RISC-V: Implement -m{,no}fence-tso

Some processors from T-Head don't implement the `fence.tso` instruction
natively and instead trap to firmware.  This breaks some users who
haven't yet updated the firmware and one could imagine it breaking users
who are trying to build firmware if they're using the C memory model.

So just add an option to disable emitting it, in a similar fashion to
how we allow users to forbid other instructions.

Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1070959
---
I've just smoke tested this one, but

void func(void) { __atomic_thread_fence(__ATOMIC_ACQ_REL); }

generates `fence.tso` without the argument and `fence rw,rw` with
`-mno-fence-tso`, so it seems to be at least mostly there.  I figured
I'd just send it up for comments before putting together the DG bits:
it's kind of a pain to carry around these workarounds for unimplemented
instructions, but it's in HW so there's not much we can do about that.

gcc/ChangeLog:

* config/riscv/riscv.opt: Add -mno-fence-tso.
* config/riscv/sync-rvwmo.md (mem_thread_fence_rvwmo): Respect
-mno-fence-tso.
* doc/invoke.texi (RISC-V): Document -mno-fence-tso.

[committed] Fix RISC-V missing stack tie

As some of you know, Raphael has been working on stack-clash support for the
RISC-V port.  A little while ago Florian reached out to us with an issue 
where
glibc was failing its smoke test due to referencing an unallocated stack 
slot.

Without diving into the code in detail I (incorrectly) concluded it was a
problem with the fallback of using Ada's stack-check paths due to not having
stack-clash support.

Once enough stack-clash bits were ready I had Raphael review the code 
generated
for Florian's test and we concluded the the original case from Florian was 
just
wrong irrespective of stack clash/stack check.  While Raphael's stack-clash
work will indirectly fix Florian's case, it really should also work without
stack-clash.

In particular this code was called out by valgrind:

In particular note the store at 0x3cbd8.  That's hitting (s1 + 960). If you
chase the values around, you'll find it's a bit more than 1k into 
unallocated
stack space.  It's also worth noting the final stack adjustment at 0x3cbf2.

While I haven't reproduced Florian's code exactly, I was able to get 
reasonably
close and verify my suspicion that everything was fine before sched2 and
incorrect after sched2.  It was also obvious at that point what had gone 
wrong
-- we were missing a stack tie after the final stack pointer adjustment.

This patch adds the missing stack tie.

While not technically a regression, I shudder at the thought of chasing one 
of
these issues down again in the wild.  Been there, done that.

Regression tested on rv64gc.  Verified the scheduler no longer mucked up
realpath by hand.  Pushing to the trunk.

[to-be-committed,RISC-V] Improve some shift-add sequences

So this is a minor fix/improvement for shift-add sequences.  This was
supposed to help xz in a minor way IIRC.

Combine may present us with (x + C2') << C1 which was canonicalized from
(x << C1) + C2.

Depending on the precise values of C2 and C2' one form may be better
than the other.  We can (somewhat awkwardly) use riscv_const_insns to
test for which sequence would be preferred.

Tested on Ventana's CI system as well as my own.  Waiting on CI results
from Rivos's tester before moving forward.

Jeff

* config/riscv/riscv.md: Add new patterns to allow selection
between (x << C1) + C2 vs (x + C2') << C1 depending on the
cost C2 vs C2'.

[Bug c++/115121] ++const_dependent_ptr is accepted in uninstantiated template

Summary|++this is accepted in   |++const_dependent_ptr is
   |uninstantiated template |accepted in uninstantiated
   ||template

--- Comment #1 from Andrew Pinski  ---
Slightly different testcase (without using this) which shows the issue:
```
template
int f() {
T t = 0;
T *const t1 = 
int t2 = 0;
int *const t3 = 
++t1;
//++t3;
return 0;
}

//const int t = f();
```
This should be rejected as pointer can't have an overload for operator++ even
if the pointer type has a dependent type.
GCC does reject `++t3;` but not `++t1;` at definition time.

--- Comment #1 from Andrew Pinski  ---
When I do cross back builds, I normally don't rebuild the target libraries and
just use the already built target libraries from the cross builds. Since you
are now building the target libraries twice and you really don't need to
though.

[Bug sanitizer/115127] [12/13/14/15 Regression] passing zero to __builtin_ctz() check missing

[pinskia at gcc dot gnu.org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115127

--- Comment #2 from Andrew Pinski  ---
Also I tested even the simplified testcase:
```
volatile int t = 1;

int main (int argc, char* argv[])
{
volatile int print_hash_value = 0;
if (t == 2) print_hash_value = 1;
__builtin_ctz(print_hash_value);
return 0;
}
```
And the trunk reports:
/app/example.cpp:261:5: runtime error: passing zero to ctz(), which is not a
valid argument

Just fine.

[C PATCH] Fix for redeclared enumerator initialized with different type [PR115109]

[Martin Uecker]

Bootstrapped and regression tested on x86_64



c23: Fix for redeclared enumerator initialized with different type 
[PR115109]

c23 specifies that the type of a redeclared enumerator is the one of the
previous declaration.  Convert initializers with different type accordingly
and add -Woverflow warning.

  enumerator convert value to previous type.

Confirmed. GCC does have some code that handles some of this in phiopt but not
in a generic way.

Jump threading can handle:
```
int src1(unsigned a, unsigned b, int c) {
unsigned phi;
if(c) {
dummy();
phi = a < 5 ? a : 5;
} else {
phi = b;
}
if (phi < 6)
  dummy();
}
```

But not:
```
int src(unsigned a, unsigned b, int c) {
unsigned phi;
if(c) {
dummy();
phi = a < 5 ? a : 5;
} else {
phi = b;
}
return (phi < 6);
 dummy();
}
```

[Jeff Law via Gcc-cvs]

commit a5445260bd42d74aabe6c11d6207d113aafe2c8c
Author: Xiao Zeng 
Date:   Wed May 15 16:23:16 2024 +0800

RISC-V: Fix "Nan-box the result of movbf on soft-bf16"

1 According to unpriv-isa spec:


  1.1 "FMV.H.X moves the half-precision value encoded in IEEE 754-2008
  standard encoding from the lower 16 bits of integer register rs1
  to the floating-point register rd, NaN-boxing the result."
  1.2 "FMV.W.X moves the single-precision value encoded in IEEE 754-2008
  standard encoding from the lower 32 bits of integer register rs1
  to the floating-point register rd. The bits are not modified in the
  transfer, and in particular, the payloads of non-canonical NaNs are 
preserved."

2 When (!TARGET_ZFHMIN == true && TARGET_HARD_FLOAT == true), instruction 
needs
to be added to complete the Nan-box, as done in
"RISC-V: Nan-box the result of movhf on soft-fp16":



3 Consider the "RISC-V: Nan-box the result of movbf on soft-bf16" in:


It ignores that both hf16 and bf16 are 16bits floating-point.

4 zfbfmin -> zfhmin in:



gcc/ChangeLog:

* config/riscv/riscv.cc (riscv_legitimize_move): Optimize movbf
with Nan-boxing value.
* config/riscv/riscv.md (*movhf_softfloat_boxing): Expand movbf
with Nan-boxing value.
(*mov_softfloat_boxing): Ditto.
with Nan-boxing value.
(*movbf_softfloat_boxing): Delete abandon pattern.

commit d6cb9a0d984a6c9ea0b548178a5cf79629be073b
Author: Robin Dapp 
Date:   Mon Feb 26 13:09:15 2024 +0100

RISC-V: Add initial cost handling for segment loads/stores.

This patch makes segment loads and stores more expensive.  It adds
segment_permute_2 as well as 3 to 8 cost fields to the common vector
costs and adds handling to adjust_stmt_cost.

gcc/ChangeLog:

* config/riscv/riscv-protos.h (struct common_vector_cost): Add
segment_permute cost.
* config/riscv/riscv-vector-costs.cc (costs::adjust_stmt_cost):
Handle segment loads/stores.
* config/riscv/riscv.cc: Initialize segment_permute_[2-8] to 1.

gcc/testsuite/ChangeLog:

* gcc.dg/vect/costmodel/riscv/rvv/pr113112-4.c: Adjust test.

RISC-V: Implement IFN SAT_ADD for both the scalar and vector

The patch implement the SAT_ADD in the riscv backend as the
sample for both the scalar and vector.  Given below vector
as example:

void vec_sat_add_u64 (uint64_t *out, uint64_t *x, uint64_t *y, unsigned n)
{
  unsigned i;

  for (i = 0; i < n; i++)
out[i] = (x[i] + y[i]) | (- (uint64_t)((uint64_t)(x[i] + y[i]) < x[i]));
}

Before this patch:
vec_sat_add_u64:
  ...
  vsetvli a5,a3,e64,m1,ta,ma
  vle64.v v0,0(a1)
  vle64.v v1,0(a2)
  sllia4,a5,3
  sub a3,a3,a5
  add a1,a1,a4
  add a2,a2,a4
  vadd.vv v1,v0,v1
  vmsgtu.vv   v0,v0,v1
  vmerge.vim  v1,v1,-1,v0
  vse64.v v1,0(a0)
  ...

After this patch:
vec_sat_add_u64:
  ...
  vsetvli a5,a3,e64,m1,ta,ma
  vle64.v v1,0(a1)
  vle64.v v2,0(a2)
  sllia4,a5,3
  sub a3,a3,a5
  add a1,a1,a4
  add a2,a2,a4
  vsaddu.vv   v1,v1,v2  <=  Vector Single-Width Saturating Add
  vse64.v v1,0(a0)
  ...

The below test suites are passed for this patch.
* The riscv fully regression tests.
* The aarch64 fully regression tests.
* The x86 bootstrap tests.
* The x86 fully regression tests.

RISC-V: Enable vectorizable early exit testsuite

After we supported vectorizable early exit in RISC-V,  we would like to
enable the gcc vect test for vectorizable early test.

The vect-early-break_124-pr114403.c failed to vectorize for now.
Because that the __builtin_memcpy with 8 bytes failed to folded into
int64 assignment during ccp1.  We will improve that first and mark
this as xfail for RISC-V.

The below tests are passed for this patch:
1. The riscv fully regression tests.

gcc/testsuite/ChangeLog:

* gcc.dg/vect/slp-mask-store-1.c: Add pragma novector as it will
have 2 times LOOP VECTORIZED in RISC-V.
* gcc.dg/vect/vect-early-break_124-pr114403.c: Xfail for the
riscv backend.
* lib/target-supports.exp: Add RISC-V backend.

RISC-V: Implement vectorizable early exit with vcond_mask_len

After we support the loop lens for the vectorizable,  we would like to
implement the feature for the RISC-V target.  Given below example:

unsigned vect_a[1923];
unsigned vect_b[1923];

void test (unsigned limit, int n)
{
  for (int i = 0; i < n; i++)
{
  vect_b[i] = limit + i;

  if (vect_a[i] > limit)
{
  ret = vect_b[i];
  return ret;
}

  vect_a[i] = limit;
}
}

  ...

  swa3,0(a5)
  addiw a0,a0,1
  addi  a4,a4,4
  addi  a5,a5,4
  beq   a1,a0,.L2
.L4:
  swa0,0(a4)
  lwa2,0(a5)
  bleu  a2,a3,.L8
  ret

[Jeff Law via Gcc-cvs]

https://gcc.gnu.org/g:4ec3a6b6022c1853cfd5866dea0324a4002413b2

commit 4ec3a6b6022c1853cfd5866dea0324a4002413b2
Author: Pan Li 
Date:   Thu May 16 09:58:13 2024 +0800

Vect: Support loop len in vectorizable early exit

This patch adds early break auto-vectorization support for target which
use length on partial vectorization.  Consider this following example:

unsigned vect_a[802];
unsigned vect_b[802];

void test (unsigned x, int n)
{
  for (int i = 0; i < n; i++)
  {
vect_b[i] = x + i;

if (vect_a[i] > x)
  break;

vect_a[i] = x;
  }
}

We use VCOND_MASK_LEN to simulate the generate (mask && i < len + bias).
And then the IR of RVV looks like below:

  ...
  _87 = .SELECT_VL (ivtmp_85, POLY_INT_CST [32, 32]);
  _55 = (int) _87;
  ...
  mask_patt_6.13_69 = vect_cst__62 < vect__3.12_67;
  vec_len_mask_72 = .VCOND_MASK_LEN (mask_patt_6.13_69, { -1, ... }, \
{0, ... }, _87, 0);
  if (vec_len_mask_72 != { 0, ... })
goto ; [5.50%]
  else
goto ; [94.50%]

The below tests are passed for this patch:
1. The riscv fully regression tests.
2. The x86 bootstrap tests.
3. The x86 fully regression tests.

gcc/ChangeLog:

* tree-vect-loop.cc (vect_gen_loop_len_mask): New func to gen
the loop len mask.
* tree-vect-stmts.cc (vectorizable_early_exit): Invoke the
vect_gen_loop_len_mask for 1 or more stmt(s).
* tree-vectorizer.h (vect_gen_loop_len_mask): New func decl
for vect_gen_loop_len_mask.

Internal-fn: Support new IFN SAT_ADD for unsigned scalar int

This patch would like to add the middle-end presentation for the
saturation add.  Aka set the result of add to the max when overflow.
It will take the pattern similar as below.

SAT_ADD (x, y) => (x + y) | (-(TYPE)((TYPE)(x + y) < x))

Take uint8_t as example, we will have:

* SAT_ADD (1, 254)   => 255.
* SAT_ADD (1, 255)   => 255.
* SAT_ADD (2, 255)   => 255.
* SAT_ADD (255, 255) => 255.

Given below example for the unsigned scalar integer uint64_t:

uint64_t sat_add_u64 (uint64_t x, uint64_t y)
{
  return (x + y) | (- (uint64_t)((uint64_t)(x + y) < x));
}

Before this patch:
uint64_t sat_add_uint64_t (uint64_t x, uint64_t y)
{
  long unsigned int _1;
  _Bool _2;
  long unsigned int _3;
  long unsigned int _4;
  uint64_t _7;
  long unsigned int _10;
  __complex__ long unsigned int _11;

;;   basic block 2, loop depth 0
;;pred:   ENTRY
  _11 = .ADD_OVERFLOW (x_5(D), y_6(D));
  _1 = REALPART_EXPR <_11>;
  _10 = IMAGPART_EXPR <_11>;
  _2 = _10 != 0;
  _3 = (long unsigned int) _2;
  _4 = -_3;
  _7 = _1 | _4;
  return _7;
;;succ:   EXIT

}

After this patch:
uint64_t sat_add_uint64_t (uint64_t x, uint64_t y)
{
  uint64_t _7;

;;   basic block 2, loop depth 0
;;pred:   ENTRY
  _7 = .SAT_ADD (x_5(D), y_6(D)); [tail call]
  return _7;
;;succ:   EXIT
}

The below tests are passed for this patch:
1. The riscv fully regression tests.
3. The x86 bootstrap tests.
4. The x86 fully regression tests.

Vect: Support new IFN SAT_ADD for unsigned vector int

For vectorize, we leverage the existing vect pattern recog to find
the pattern similar to scalar and let the vectorizer to perform
the rest part for standard name usadd3 in vector mode.
The riscv vector backend have insn "Vector Single-Width Saturating
Add and Subtract" which can be leveraged when expand the usadd3
in vector mode.  For example:

void vec_sat_add_u64 (uint64_t *out, uint64_t *x, uint64_t *y, unsigned n)
{
  unsigned i;

  for (i = 0; i < n; i++)
out[i] = (x[i] + y[i]) | (- (uint64_t)((uint64_t)(x[i] + y[i]) < x[i]));
}

Before this patch:
void vec_sat_add_u64 (uint64_t *out, uint64_t *x, uint64_t *y, unsigned n)
{
  ...
  _80 = .SELECT_VL (ivtmp_78, POLY_INT_CST [2, 2]);
  ivtmp_58 = _80 * 8;
  vect__4.7_61 = .MASK_LEN_LOAD (vectp_x.5_59, 64B, { -1, ... }, _80, 0);
  vect__6.10_65 = .MASK_LEN_LOAD (vectp_y.8_63, 64B, { -1, ... }, _80, 0);
  vect__7.11_66 = vect__4.7_61 + vect__6.10_65;
  mask__8.12_67 = vect__4.7_61 > vect__7.11_66;
  vect__12.15_72 = .VCOND_MASK (mask__8.12_67, { 18446744073709551615,
... }, vect__7.11_66);
  .MASK_LEN_STORE (vectp_out.16_74, 64B, { -1, ... }, _80, 0, 
vect__12.15_72);
  vectp_x.5_60 = vectp_x.5_59 + ivtmp_58;
  vectp_y.8_64 = vectp_y.8_63 + ivtmp_58;
  vectp_out.16_75 = vectp_out.16_74 + ivtmp_58;
  ivtmp_79 = ivtmp_78 - _80;
  ...
}

After this patch:
void vec_sat_add_u64 (uint64_t *out, uint64_t *x, uint64_t *y, unsigned n)
{
  ...
  _62 = .SELECT_VL (ivtmp_60, POLY_INT_CST [2, 2]);
  ivtmp_46 = _62 * 8;
  vect__4.7_49 = .MASK_LEN_LOAD (vectp_x.5_47, 64B, { -1, ... }, _62, 0);
  vect__6.10_53 = .MASK_LEN_LOAD (vectp_y.8_51, 64B, { -1, ... }, _62, 0);
  vect__12.11_54 = .SAT_ADD (vect__4.7_49, vect__6.10_53);
  .MASK_LEN_STORE (vectp_out.12_56, 64B, { -1, ... }, _62, 0, 
vect__12.11_54);
  ...
}

RISC-V: testsuite: Drop march-string in cmpmemsi/cpymemsi tests

The tests cmpmemsi-1.c and cpymemsi-1.c are execution ("dg-do run")
tests, which does not have any restrictions for the enabled extensions.
Further, no other listed options are required.
Let's drop the options, so that the test can also be executed on
non-f and non-d targets.  However, we need to set options to the
defaults without '-ansi', because the included test file uses the
'asm' keyword, which is not part of ANSI C.

gcc/testsuite/ChangeLog:

* gcc.target/riscv/cmpmemsi-1.c: Drop options.
* gcc.target/riscv/cpymemsi-1.c: Likewise.
