This avoids repeatedly calling Unqualify on the same node, removes a dead
call to Generate_Finalization_Actions, a redundant setting of Assignment_OK
and reuses a local variable more consistently. No functional changes.

* exp_aggr.adb (Build_Record_Aggr_Code): Add new variable Ancestor_Q

Init_Typ in lieu of Etype (Ancestor) more consistently.

This happens when the ancestor part is itself an aggregate: in this case,

The expansion is incorrect in the case where the initialization expression
of a component is a conditional expression that has a function call as one
of its dependent expressions, leading to a wrong order of initialization,
adjustment and finalization.

* exp_aggr.adb (Initialize_Component): Perform immediate expansion
of the initialization expression if it is a conditional expression
and the component type is controlled.
|

The final processing at the component level of array aggregates and record
aggregates is very similar, so this factors out the common processing into
three new library-level subprograms.
There should be no functional changes, but the expanded code may be changed
in the case of controlled components of array aggregates not covered by a
multiple choice: the previous expansion used to place new declarations prior
to the aggregate in this case and that is no longer the case, i.e. they are
always placed right before the initialization of the component (as was done
for all controlled components of record aggregates and controlled components
of array aggregates covered by a multiple choice).

New aspect Ghost_Predicate allows the use of ghost entities in the
predicate expression, even if the type is not ghost itself. As a result,
subtypes with a ghost predicate cannot be used in membership tests.
Subtypes with ghost predicates are subject to the same additional
restrictions as subtypes with aspect Dynamic_Predicate.
They are governed for compilation by assertion policy Ghost.
Checking of the predicate itself is governed by the usual assertion
policy (Static_Predicate/Dynamic_Predicate/Predicate) independently
of the ghost predicate.

We create wrapper functions associated with inherited functions with
controlling results which are not overridden during freezing. We partly
decorated them explicitly, even though they would be fully decorated
later anyway.
This early decoration didn't work as expected, because flag
In_Private_Part that is read by Override_Dispatching_Operation it not
set reliably while freezing (as explained in the comment of
Is_Private_Declaration). In effect, we were getting a circularity
between Alias and Overridden_Operation, which was causing GNATprove to
loop infinitely.
Apparently the cleanest fix is to not decorate the wrapper with an early
call to Override_Dispatching_Operation.
gcc/ada/
* exp_ch3.adb (Make_Controlling_Function_Wrappers): Remove early
decoration.

This PR optimizes an SVE intrinsics sequence where
svlasta (svptrue_pat_b8 (SV_VL1), x)
a scalar is selected based on a constant predicate and a variable vector.
This sequence is optimized to return the correspoding element of a NEON
vector. For eg.
svlasta (svptrue_pat_b8 (SV_VL1), x)
returns
umov w0, v0.b[1]
Likewise,
svlastb (svptrue_pat_b8 (SV_VL1), x)
returns
umov w0, v0.b[0]
This optimization only works provided the constant predicate maps to a range
that is within the bounds of a 128-bit NEON register.

This patch fixes the requirement of V_WHOLE and V_FRACT.
E.g. VNx8QI in V_WHOLE has no requirement which is incorrect.
Actually, VNx8QI should be whole(full) mode when TARGET_MIN_VLEN < 128
since when TARGET_MIN_VLEN == 128, VNx8QI is e8mf2 which is fractional
vector.

According to RVV ISA:
https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc
We can enhance VLA SLP auto-vectorization with (16.5.1. Synthesizing vdecompress)
Decompress operation.
Case 1 (nunits = POLY_INT_CST [16, 16]):
_48 = VEC_PERM_EXPR <_37, _35, { 0, POLY_INT_CST [16, 16], 1, POLY_INT_CST [17, 16], 2, POLY_INT_CST [18, 16], ... }>;
We can optimize such VLA SLP permuation pattern into:
_48 = vdecompress (_37, _35, mask = { 0, 1, 0, 1, ... };
Case 2 (nunits = POLY_INT_CST [16, 16]):
_23 = VEC_PERM_EXPR <_46, _44, { POLY_INT_CST [1, 1], POLY_INT_CST [3, 3], POLY_INT_CST [2, 1], POLY_INT_CST [4, 3], POLY_INT_CST [3, 1], POLY_INT_CST [5, 3], ... }>;
We can optimize such VLA SLP permuation pattern into:
_48 = vdecompress (slidedown(_46, 1/2 nunits), slidedown(_44, 1/2 nunits), mask = { 0, 1, 0, 1, ... };
For example:
void __attribute__ ((noinline, noclone))
vec_slp (uint64_t *restrict a, uint64_t b, uint64_t c, int n)
{
for (int i = 0; i < n; ++i)
{
a[i * 2] += b;
a[i * 2 + 1] += c;
}
}
ASM:
...
vid.v v0
vand.vi v0,v0,1
vmseq.vi v0,v0,1 ===> mask = { 0, 1, 0, 1, ... }
vdecompress:
viota.m v3,v0

Loop:
vsetvli zero,a5,e64,m1,ta,ma

clobbers
So as Georg-Johann discusses in the BZ, reload_cse_move2add can generate
incorrect code when optimizing code with clobbers. Specifically in the
case where we try to optimize a sequence of 4 operations down to 3
operations we can reset INSN to the next instruction and continue the loop.
That skips the code to invalidate objects based on things like REG_INC
nodes, stack pushes and most importantly clobbers attached to the current
insn.
This patch factors all of the invalidation code used by reload_cse_move2add
into a new function and calls it at the appropriate time.
Georg-Johann has confirmed this patch fixes his avr bug and I've had it in
my tester over the weekend. It's bootstrapped and regression tested on
aarch64, m68k, sh4, alpha and hppa. It's also regression tested successfully
on a wide variety of other targets.

Reduce number of enum values passed to libgomp as
GOMP_MAP_PRESENT_{TO,TOFROM,FROM,ALLOC} have the same semantic as
GOMP_MAP_FORCE_PRESENT (i.e. abort if not present, otherwise ignore);
that's different to GOMP_MAP_ALWAYS_PRESENT_{TO,TOFROM,FROM} which also
abort if not present but copy data when present. This is is a follow-up to
the commit r14-1579-g4ede915d5dde93 done 6 days ago.

The test will fail on below command with multi-thread like below. However,
it comes from one missed "Oz" option when check vsetvl.
make -j $(nproc) report RUNTESTFLAGS="rvv.exp riscv.exp"
To some reason, this failure cannot be reproduced by RUNTESTFLAGS="rvv.exp"
or make without -j option. We would like to fix it and root cause the
reason later.

Alias analysis was treating .MASK_STORE as storing a full vector
which means we disambiguate against decls of smaller than vector size.
That's of course wrong and a similar issue was fixed for DSE already.
The following makes sure we set the size of the access to unknown
and only constrain max_size.
This fixes runtime execution FAILs of gfortran.dg/matmul_2.f90,
gfortran.dg/matmul_6.f90 and gfortran.dg/pr91577.f90 when using
AVX512 with full masked loop vectorization on Zen4.
* tree-ssa-alias.cc (call_may_clobber_ref_p_1): For
.MASK_STORE and friend set the size of the access to
unknown.

This patch implements RTL constant-folding for the SS_TRUNCATE and US_TRUNCATE codes.
The semantics are a clamping operation on the argument with the min and max of the narrow mode,
followed by a truncation. The signedness of the clamp and the min/max extrema is derived from
the signedness of the saturating operation.
We have a number of instructions in aarch64 that use SS_TRUNCATE and US_TRUNCATE to represent
their operations and we have pretty thorough runtime tests in gcc.target/aarch64/advsimd-intrinsics/vqmovn*.c.
With this patch the instructions are folded away at optimisation levels and the correctness checks still
pass.
Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf.
gcc/ChangeLog:
* simplify-rtx.cc (simplify_const_unary_operation):
Handle US_TRUNCATE, SS_TRUNCATE.
