As explained in PR82524, LRA is not able to reload strict_low_part inout
operand with matched input operand. The patch introduces a workaround,
where we allow LRA to generate an instruction with non-matched input operand
which is split post reload to an instruction that inserts non-matched input
operand to an inout operand and the instruction that uses matched operand.
The generated code improves from:
movsbl %dil, %edx
movl %edi, %eax
sall $3, %edx
movb %dl, %al
to:
movl %edi, %eax
movb %dil, %al
salb $3, %al
which is still not optimal, but the code is one instruction shorter and
does not use a temporary register.

The following example
void f10(double * restrict z, double * restrict w, double * restrict x,
double * restrict y, int n)
{
for (int i = 0; i < n; i++) {
z[i] = (w[i] > 0) ? x[i] + w[i] : y[i] - w[i];
}
}
generates currently:
ld1d z1.d, p1/z, [x1, x5, lsl 3]
fcmgt p2.d, p1/z, z1.d, #0.0
fcmgt p0.d, p3/z, z1.d, #0.0
ld1d z2.d, p2/z, [x2, x5, lsl 3]
bic p0.b, p3/z, p1.b, p0.b
ld1d z0.d, p0/z, [x3, x5, lsl 3]
where a BIC is generated between p1 and p0 where a NOT would be better here
since we won't require the use of p3 and opens the pattern up to being CSEd.
After this patch using a 2 -> 2 split we generate:
ld1d z1.d, p0/z, [x1, x5, lsl 3]
fcmgt p2.d, p0/z, z1.d, #0.0
not p1.b, p0/z, p2.b
The additional scratch is needed such that we can CSE the two operations. If
both statements wrote to the same register then CSE won't be able to CSE the
values if there are other statements in between that use the register.
A second pattern is needed to capture the nor case as combine will match the
longest sequence first. So without this pattern we end up de-optimizing nor
and instead emit two nots. I did not find a better way to do this.

there can't be any padding
We can use the clear_padding_type_may_have_padding_p function, which
is conservative for e.g. RECORD_TYPE/UNION_TYPE, but for the floating and
complex floating types is accurate. clear_type_padding_in_mask is
more expensive because we need to allocate memory, fill it, call the function
which itself is more expensive and then analyze the memory, so for the
common case of float/double atomics or even long double on most targets
we can avoid that.

> * testsuite/libgomp.c++/scan-10.C: Add option -fvect-cost-model=cheap.
I don't think this is the right thing to do.
This just means that at some point between 2013 when -fsimd-cost-model has
been introduced and now -fsimd-cost-model= option at least partially stopped
working properly.
As documented, -fsimd-cost-model= overrides the -fvect-cost-model= setting
for OpenMP simd loops (loop->force_vectorize is true) if specified differently
from default.
In tree-vectorizer.h we have:
static inline bool
unlimited_cost_model (loop_p loop)
{
if (loop != NULL && loop->force_vectorize
&& flag_simd_cost_model != VECT_COST_MODEL_DEFAULT)
return flag_simd_cost_model == VECT_COST_MODEL_UNLIMITED;
return (flag_vect_cost_model == VECT_COST_MODEL_UNLIMITED);
}
and use it in various places, but we also just use flag_vect_cost_model
in lots of places (and in one spot use flag_simd_cost_model, not sure if
we are sure it is a force_vectorize loop or what).
So, IMHO we should change the above inline function to
loop_cost_model and let it return the cost model and then just
reimplement unlimited_cost_model as
return loop_cost_model (loop) == VECT_COST_MODEL_UNLIMITED;
and then adjust the direct uses of the flag and revert these changes.

Commonize the three paths to produce constraints for function call
and makes it more flexible, so we can implement new features more easily. Main
idea is to not special case pure and const since we can now describe all of
pure/const via their EAF flags (implicit_const_eaf_flags and
implicit_pure_eaf_flags) and info on existence of global memory loads/stores in
function which is readily available in the modref tree.
While rewriting the function, I dropped some of optimizations in the way we
generate constraints. Some of them we may want to add back, but I think the
constraint solver should be fast to get rid of them quickly, so it looks like
bit of premature optimization.
We now always produce one additional PTA variable (callescape) for things that
escape into function call and thus can be stored to parameters or global memory
(if modified). This is no longer the same as global escape in case function is
not reading global memory. It is also not same as call use, since we now
understand the fact that interposable functions may use parameter in a way that
is not releavnt for PTA (so we can not optimize out stores initializing the
memory, but we can be safe about fact that pointers stored does not escape).
Compared to previous code we now handle correctly EAF_NOT_RETURNED in all cases
(previously we did so only when all parameters had the flag) and also handle
NOCLOBBER in more cases (since we make difference between global escape and
call escape). Because I commonized code handling args and static chains, we
could now easily extend modref to also track flags for static chain and return
slot which I plan to do next.
Otherwise I put some effort into producing constraints that produce similar
solutions as before (so it is harder to debug differences). For example if
global memory is written one can simply move callescape to escape rather then
making everything escape by its own constraints, but it affects ipa-pta
testcases.

The following fixes the issue of ignoring side-effects on memory
from overloaded global new/delete operators by not marking them
as effectively 'const' apart from other explicitely specified
side-effects.
This will cause
FAIL: g++.dg/warn/Warray-bounds-16.C -std=gnu++1? (test for excess errors)
because we now no longer statically see the initialization loop
never executes because the call to operator new can now clobber 'a.m'.
This seems to be an issue with the warning code and/or ranger so
I'm leaving this FAIL to be addressed as followup.

* sem_attr.adb (Analyze_Attribute_Old_Result): Permit an
attribute reference inside a compiler-generated _Postconditions
procedure. In this case, Subp_Decl is assigned the declaration
of the enclosing subprogram.
* exp_util.adb (Insert_Actions): When climbing up the tree
looking for an insertion point, do not climb past an
N_Iterated_Component/Element_Association, since this could
result in inserting a reference to a loop parameter at a
location outside of the scope of that loop parameter. On the
other hand, be careful to preserve existing behavior in the case
of an N_Component_Association node.

* exp_ch6.adb (Can_Fold_Predicate_Call): Do not attempt folding
if there is more than one predicate involved. Recall that
predicate aspect specification are additive, not overriding, and
that there are three different predicate
aspects (Dynamic_Predicate, Static_Predicate, and the
GNAT-defined Predicate aspect). These various ways of
introducing multiple predicates are all checked for. A new
nested function, Augments_Other_Dynamic_Predicate, is
introduced.
* sem_ch4.adb
(Analyze_Indexed_Component_Form.Process_Function_Call): When
determining whether a name like "X (Some_Discrete_Type)" might
be interpreted as a slice, the answer should be "no" if the
type/subtype name denotes the current instance of type/subtype.
