Now that the generic parts of the binary operators have been
abstracted, implementing MINUS_EXPR is a cinch.

The op[12]_range entries will be submitted as a follow-up.

gcc/ChangeLog:

	* range-op-float.cc (class foperator_minus): New.
	(floating_op_table::floating_op_table): Add MINUS_EXPR entry.

The PLUS_EXPR was always meant to be a template for further
development, since most of the binary operators will share a similar
structure.  This patch abstracts out the common bits into the default
definition for range_operator_float::fold_range() and provides an
rv_fold() to be implemented by the individual entries wishing to use
the generic folder.  This is akin to what we do with fold_range() and
wi_fold() in the integer version of range-ops.

	* range-op.h (class range_operator_float): Add rv_fold.

Some combinations of operations can yield a NAN even if no operands
have the possiblity of a NAN.  For example, [-INF] + [+INF] = NAN and
vice versa.

For [-INF,+INF] + [-INF,+INF], frange_arithmetic will not return a
NAN, and since the operands have no possibility of a NAN, we will
mistakenly assume the result cannot have a NAN.  This fixes the
oversight.

   removing the std::move may not be correct for a different

In r12-3094-ge82e0f149b0aba I added the assumption that
POINTER_PLUS_EXPR of non-NULL is non-NULL (for PR analyzer/101962).

Whilst working on another bug, I noticed that this only works
when the LHS is known to be non-NULL via
region_model::eval_condition_without_cm, but not when it's known through
a constraint.

This distinction predates the original commit of the analyzer in GCC 10,
but I believe it became irrelevant in the GCC 11 rewrite of the region
model code (r11-2694-g808f4dfeb3a95f).

Hence this patch eliminates region_model::eval_condition_without_cm in
favor of all users simply calling region_model::eval_condition.  Doing
so enables the "POINTER_PLUS_EXPR of non-NULL is non-NULL" assumption to
also be made when the LHS is known through a constraint (e.g. a
conditional).

`basic_filebuf::xsputn` would bypass the buffer when passed a chunk of
size 1024 and above, seemingly as an optimisation.

This can have a significant performance impact if the overhead of a
`write` syscall is non-negligible, e.g. on a slow disk, on network
filesystems, or simply during IO contention because instead of flushing
every `BUFSIZ` (by default), we can flush every 1024 char.
The impact is even greater with custom larger buffers, e.g. for network
filesystems, because the code could issue `write` for example 1000X more
often than necessary with respect to the buffer size.
It also introduces a significant discontinuity in performance when
writing chunks of size 1024 and above.

Instead, it makes sense to only bypass the buffer if the amount of data
to be written is larger than the buffer capacity.

Until now operator+(char*, string) and operator+(string, char*) had
different performance characteristics. The former required a single
memory allocation and the latter required two. This patch makes the
performance equal.

After consultation with Jonathan, it seemed like a good idea to create a
single function that performed one-allocation string concatenation that
could be used by various different version of operator+. This patch adds
such a function and calls it from the relevant implementations.

This is the range-op entry for floating point PLUS_EXPR.  It's the
most intricate range entry we have so far, because we need to keep
track of rounding and target FP formats.  This will be the last FP
entry I commit, mostly to avoid disturbing the tree any further, and
also because what we have so far is enough for a solid VRP.

So far we track NANs and signs correctly.  We also handle relationals
(symbolics and numeric), both ordered and unordered, ABS_EXPR and
NEGATE_EXPR which are used to fold __builtin_isinf, and __builtin_sign
(__builtin_copysign is coming up).  All in all, I think this provide
more than enough for basic VRP on floats, as well as provide a basis
to flesh out the rest if there's interest.

My goal with this entry is to provide a template for additional binary
operators, as they tend to follow a similar pattern: handle NANs, do
the arithmetic while keeping track of rounding, and adjust for NAN.  I
may abstract the general parts as we do for irange's fold_range and
wi_fold.

After Jakub and Richi's suggestion of using the same representation
for tracking known bits as we do in CCP, I took a peek at the code and
realized there's a plethora of bit-tracking code there that we could
be sharing with range-ops.  For example, the multiplication
optimizations are way better than what I had cobbled together.  For
that matter, our maybe nonzero tracking as a whole has a lot of room
for improvement.  Being the lazy ass that I am, I think we should just
use one code base (CCP's).

This patch provides a thin wrapper for converting the irange maybe
nonzero bits to what CCP requires, and uses that to call into
bit_value_binop().  I have so far converted the MULT_EXPR range-op
entry to use it, as the DIV_EXPR entry we have gets a case CCP doesn't
get so I'd like to contribute the enhancement to CCP before converting
over.

I'd like to use this approach with the dozen or so tree_code's that
are handled in CCP, thus saving us from having to implement any of
them :).

Early next season I'd like to change irange's internal representation
to a pair of value / mask, and start tracking all known bits.  This
ties in nicely with our plan for tracking known set bits.

Perhaps if the stars align, we could merge the bit twiddling in CCP
into range-ops and have a central repository for it.  That is, once we
make the switch to wide-ints, and assuming there are no performance
issues.  Note that range-ops is our lowest level abstraction.
i.e. it's just the math, there's no GORI or ranger, or even the
concept of a symbolic or SSA.

	PR testsuite/107171
	* gcc.target/powerpc/pr105586.c: Guard against unsupported

I've missed that this function needs to handle all the builtins that
are handled in can_test_argument_range.
The following patch does that.  For many of the builtins (like acos, or
log) it is the same range regardless of the floating point type, but for
some (cosh, sinh, exp{,m1,2}) it is different for each format,
so I had to compute those ranges.

Note, seems the existing ranges were in some cases (e.g. for exp2)
the smallest in absolute value which results infinite result, in others
the largest which still results in finite result (but consistently so
for the IEEE single vs. double).  I've followed that for IEEE half and
quad cases too, just am not sure why it was like that.  I think
get_domain with true, false is open interval rather than closed
and the comments indicate that too, conservatively that is certainly
correct.

OT, with frange, perhaps we could DCE the calls unconditionally if
frange can prove we are in the domain range.

For integer vector comparisons without XOP before AVX512{F,VL} we are
constrained by only GT and EQ being supported in HW.
For GTU we play tricks to implement it using GT or unsigned saturating
subtraction, for LT/LTU we swap the operands and thus turn it into
GT/GTU.  For LE/LEU we handle it by using GT/GTU and negating the
result and for GE/GEU by using GT/GTU on swapped operands and negating
the result.
If the second operand is a CONST_VECTOR, we can usually do better though,
we can avoid the negation.  For LE/LEU cst by doing LT/LTU cst+1 (and
then cst+1 GT/GTU x) and for GE/GEU cst by doing GT/GTU cst-1, provided
there is no wrap-around on those cst+1 or cst-1.
GIMPLE canonicalizes x < cst to x <= cst-1 etc. (the rule is smaller
absolute value on constant), but only for scalars or uniform vectors,
so in some cases this undoes that canonicalization in order to avoid
the extra negation, but it handles also non-uniform constants.

	PR target/107546
	* config/i386/predicates.md (vector_or_const_vector_operand): New
	predicate.
	* config/i386/sse.md (vec_cmp<mode><sseintvecmodelower>,
	vec_cmpv2div2di, vec_cmpu<mode><sseintvecmodelower>,
	vec_cmpuv2div2di): Use nonimmediate_or_const_vector_operand
	predicate instead of nonimmediate_operand and
	vector_or_const_vector_operand instead of vector_operand.
	* config/i386/i386-expand.cc (ix86_expand_int_sse_cmp): For
	LE/LEU or GE/GEU with CONST_VECTOR cop1 try to transform those
	into LE/LEU or GT/GTU with larger or smaller by one cop1 if
	there is no wrap-around.  Force CONST_VECTOR cop0 or cop1 into
	REG.  Formatting fix.

	* gcc.target/i386/pr107546.c: New test.

As r13-3609-g6d9dbdf51f9afe8 has been committed, we can now enable
even the denorm_min test.

2022-11-08  Jakub Jelinek  <jakub@redhat.com>

	* testsuite/20_util/to_chars/float128_c++23.cc (test): Uncomment
	denorm_min test.

gcc/
	PR rtl-optimization/107482
	* ira-color.cc (assign_hard_reg): Only call
	update_costs_from_copies when retry_p is false.

When the allocator is of an unconstrained array type and has an initializing
expression, the copy of the initializing expression must be done separately
from that of the bounds.

gcc/ada/

	* gcc-interface/utils2.cc (build_allocator): For unconstrained
	array types with a storage model and an initializing expression,
	copy the initialization expression separately from the bounds. In
	all cases with a storage model, pass the locally computed size for
	the store.

In the case of Some_Enumeration_Type'Image (<some static value>),
the compiler will replace this expression in its internal program
representation with a corresponding string literal. This is incorrect
if the Put_Image aspect has been specified (directly or via inheritance)
for the enumeration type.

gcc/ada/

	* sem_attr.adb
	(Eval_Attribute): Don't simplify 'Image call if Put_Image has been
	specified.

Code cleanup; semantics is unaffected.

gcc/ada/

	* exp_ch6.adb, exp_put_image.adb, sem_aggr.adb, sem_attr.adb,
	sem_ch5.adb, sem_type.adb, sem_util.adb: Replace
	"Present (Find_Aspect (...))" with "Has_Aspect".

Before this patch, a classwide contract expression was preanalyzed
only when its primitive operation's type was frozen. It caused name
resolution to be off in the cases where the freezing took place
after the end of the declaration list the primitive operation was
declared in.

This patch makes it so that if the compiler gets to the end of
the declaration list before the type is frozen, it preanalyzes the
classwide contract expression, so that the names are resolved in the
right context.

gcc/ada/

	* contracts.adb
	(Preanalyze_Class_Conditions): New procedure.
	(Preanalyze_Condition): Moved out from Merge_Class_Conditions in
	order to be spec-visible.
	* contracts.ads
	(Preanalyze_Class_Conditions): New procedure.
	* sem_prag.adb
	(Analyze_Pre_Post_Condition_In_Decl_Part): Call
	Preanalyze_Class_Conditions when necessary.
