Do not specify NAN sign in frange::set_nonnegative.

After further reading of the IEEE 754 standard, it has become clear
that there are no guarantees with regards to the sign of a NAN when it
comes to any operation other than copy, copysign, abs, and negate.

Currently, set_nonnegative() is only used in one place in ranger
applicable to floating point values, when expanding unknown calls.
Since we already specially handle copy, copysign, abs, and negate, all
the calls to set_nonnegative() must be NAN-sign agnostic.

The cleanest solution is to leave the sign unspecificied in
frange::set_nonnegative().  Any special case, must be handled by the
caller.

gcc/ChangeLog:

* value-range.cc (frange::set_nonnegative): Remove NAN sign handling.
(range_tests_signed_zeros): Adjust test.

RISC-V: Fix selection of pipeline model for sifive-7-series

A few of the gcc.target/riscv/mcpu-*.c tests have been failing for a

unswitching of outer loops

This allows loop unswitching to unswitch outer loops conditions are
invariant in.  We restrict ourselves to unswitch conditions in innermost
loops and will only unswitch loop nests that do not contain any sibling loops.

i386: Fix up ix86_expand_int_sse_cmp [PR107585]

The following patch fixes ICE on the testcase.  I've used GEN_INT
incorrectly thinking the code punts on the problematic boundaries.
It does, but only for LE and GE, i.e. signed comparisons, for unsigned
the boundaries are 0 and unsigned maximum, so when say unsigned char
adds one to 127 or subtracts one from 128 we need to canonicalize it.

When reading back from the global store, we must clear the NAN bit if

Change the name of array_at_struct_end_p to array_ref_flexible_size_p

The name of the utility routine "array_at_struct_end_p" is misleading
and should be changed to a new name that more accurately reflects its
real meaning.

The routine "array_at_struct_end_p" is used to check whether an array
reference is to an array whose actual size might be larger than its
upper bound implies, which includes 3 different cases:

   A. a ref to a flexible array member at the end of a structure;
   B. a ref to an array with a different type against the original decl;
   C. a ref to an array that was passed as a parameter;

The old name only reflects the above case A, therefore very confusing
when reading the corresponding gcc source code.

In this patch, A new name "array_ref_flexible_size_p" is used to replace
the old name.

All the references to the routine "array_at_struct_end_p" was replaced

them clean and consistent.

Fix up foperator_abs::op1_range [PR107569]

foperator_abs::op1_range works except for the NaN handling,
from:
[frange] double [-Inf, 1.79769313486231570814527423731704356798070567525844996599e+308 (0x0.fffffffffffff8p+1024)]
lhs it computes r
[frange] double [-1.79769313486231570814527423731704356798070567525844996599e+308 (-0x0.fffffffffffff8p+1024), 1.79769313486231570814527423731704356798070567525844996599e+308
+(0x0.fffffffffffff8p+1024)] +-NAN
which is correct except for the +-NAN part.
For r before the final step it makes sure to add -NAN if there is +NAN
in the lhs range, but the final r.union_ makes it unconditional +-NAN,
because the frange ctor sets +-NAN.
So, I think we need to clear it (or have some set variant which
says not to set NAN).

This patch fixes that, but isn't enough to fix the PR, something in
the assumptions handling is still broken (and the PR has other parts).

c++: Minimal handling of carries_dependency attribute

A comment in D2552R1:
"The only questionable (but still conforming) case we found was
[[carries_dependency(some_argument)]] on GCC, where the emitted diagnostic said that the
carries_dependency attribute is not supported, but did not specifically call out the syntax error
in the argument clause."
made me try the following patch, where we'll error at least
for arguments to the attribute and for some uses of the attribute
appertaining to something not mentioned in the standard warn
with different diagnostics (or should that be an error?; clang++
does that, but I think we never do for any attribute, standard or not).
The diagnostics on toplevel attribute declaration is still an
attribute ignored warning and on empty statement different wording.

The paper additionally mentions
struct X { [[nodiscard]]; }; // no diagnostic on GCC
and 2 cases of missing diagnostics on [[fallthrough]] (guess I should
file a PR about those; one problem is that do { ... } while (0); there
is replaced during genericization just by ... and another that
[[fallthrough]] there is followed by a label, but not user/case/default
label, but an artificial one created from while loop genericization.

I've tweaked it to use long long so it passes even on the 32-bit
targets, and added an early out for weirdo targets because I think
the test assumes the usual 1/2/4/8 bytes sizes for char/short/int/long long.

PR tree-optimization/107541
* gcc.dg/tree-ssa/pr107541.c (c): Use long long type rather than long.
(main): Punt if sizeof short isn't 2, or int 4, or long long 8.

RISC-V: costs: handle BSWAP

The BSWAP operation is not handled in rtx_costs. Add it.

With Zbb, BSWAP for XLEN is a single instruction; for smaller modes,
it will expand into two.

gcc/ChangeLog:

* config/riscv/riscv.cc (riscv_rtx_costs): Add BSWAP.

LoongArch: fix signed overflow in loongarch_emit_int_compare

Signed overflow is an undefined behavior, so we need to prevent it from
happening, instead of "checking" the result.

gcc/ChangeLog:

* config/loongarch/loongarch.cc (loongarch_emit_int_compare):
Avoid signed overflow.

[range-op-float] Implement MINUS_EXPR.

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.

[range-op-float] Abstract out binary operator code out of PLUS_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.

gcc/ChangeLog:

* range-op-float.cc (range_operator_float::fold_range): Abstract
out from foperator_plus.
(range_operator_float::rv_fold): New.
(foperator_plus::fold_range): Remove.
(foperator_plus::rv_fold): New.
(propagate_nans): Remove.
* range-op.h (class range_operator_float): Add rv_fold.

[range-op-float] Set NAN possibility for INF + (-INF) and vice versa.

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.

gcc/ChangeLog:

* range-op-float.cc (foperator_plus::fold_range): Set NAN for
addition of different signed infinities.
(range_op_float_tests): New test.

c++: Tweaks for -Wredundant-move [PR107363]

Two things here:

1) when we're pointing out that std::move on a constant object is
   redundant, don't say "in return statement" when we aren't in a
   return statement;
2) suppress the warning when the std::move call was dependent, because
   removing the std::move may not be correct for a different
   instantiation of the original template.

PR c++/107363

gcc/cp/ChangeLog:

* semantics.cc (finish_call_expr): Suppress OPT_Wpessimizing_move.
* typeck.cc (maybe_warn_pessimizing_move): Check warn_redundant_move
and warning_suppressed_p.  Adjust a message depending on return_p.
(check_return_expr): Don't suppress OPT_Wpessimizing_move here.

analyzer: eliminate region_model::eval_condition_without_cm [PR101962]

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).

libstdc++: basic_filebuf: don't flush more often than necessary [PR63746]

`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.

Co-authored-by: Jonathan Wakely <jwakely@redhat.com>
libstdc++-v3/ChangeLog:

* include/bits/basic_string.h (__str_cat): Add common function
that performs single-allocation string concatenation.
(operator+): Use __str_cat.
* include/bits/basic_string.tcc (operator+): Move to .h and
define inline using __str_cat.

bpf: Use enum for resolved overloaded builtins

built-in functions to consistently use the enum bpf_builtins type,

[PR24021] Implement PLUS_EXPR range-op entry for floats.

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.

Use bit-CCP in range-ops.

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.

cdce: Fix up get_no_error_domain for new f{16,32,64,128} builtins [PR107547]

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.

i386: Improve vector [GL]E{,U} comparison against vector constants [PR107546]

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.

(Needs_BIP_Task_Actuals): Remove assertion to allow calling this
function in more contexts; in addition it returns False for functions
returning objects with foreign convention.
(Needs_BIP_Finalization_Master): Likewise.
(Needs_BIP_Alloc_Form): Likewise.
(Validate_Subprogram_Calls): Check that the number of actuals (including
extra actuals) of calls in the subtree N match their corresponding
formals.
* exp_ch6.ads
(Has_BIP_Extra_Formal): Subprogram declaration moved to the public
part of the package. In addition, a parameter has been added to
disable an assertion that requires its use with frozen entities.
(Is_Build_In_Place_Function_Call): Complete documentation.
(Validate_Subprogram_Calls): Check that the number of actuals (including
extra actuals) of calls in the subtree N match their corresponding
formals.
* freeze.adb
(Check_Itype): Add extra formals to anonymous access subprogram itypes.
(Freeze_Expression): Improve code that disables the addition of extra
formals to functions with foreign convention.

(Freeze_Subprogram): Add extra formals to non-dispatching subprograms.
* frontend.adb
(Frontend): Validate all the subprogram calls; it can be disabled using
switch -gnatd_X
* sem_ch3.adb
(Access_Subprogram_Declaration): Defer the addition of extra formals to
the freezing point so that we know the convention.
(Check_Anonymous_Access_Component): Likewise.
(Derive_Subprogram): Fix documentation.
* sem_ch6.adb

* sem_eval.adb
(Compile_Time_Known_Value): Improve predicate to avoid assertion
failure; found working on this ticket; this change does not
affect the behavior of the compiler because this subprogram
has an exception handler that returns False when the assertion
fails.
* sem_util.adb
(Needs_Result_Accessibility_Level): Do not return False for dispatching
operations compiled with Ada_Version < 2012 since they they may be
overridden by primitives compiled with Ada_Version >= Ada_2012.

ada: Move warnings switches -- initial work

This patch prepares to move warning switches from Opt into Warnsw.

gcc/ada/

* warnsw.ads, warnsw.adb, fe.h, err_vars.ads, errout.ads: Move
Warning_Doc_Switch from Err_Vars to Warnsw. Access
Warn_On_Questionable_Layout on the C side via a function rather
than a variable, because we plan to turn the variables into
renamings, and you can't Export renamings.
* erroutc.adb, switch-c.adb, errout.adb: Likewise.
* gcc-interface/decl.cc: Use Get_Warn_On_Questionable_Layout
instead of Warn_On_Questionable_Layout.
* gcc-interface/Makefile.in (GNATMAKE_OBJS): Add warnsw.o, because
it is indirectly imported via Errout.
* gcc-interface/Make-lang.in (GNATBIND_OBJS): Likewise and remove
restrict.o (not needed).

ada: Align -gnatwc's documentation with its behavior

Shortly after the -gnatwc flag was introduced, its behavior was
tweaked, but its documentation was not updated accordingly.

gcc/ada/

* doc/gnat_ugn/building_executable_programs_with_gnat.rst
(-gnatwc): Fix flag documentation.
* gnat_ugn.texi: Regenerate.

ada: Improve handling of declare expressions in deferred-freezing contexts

In some cases where a declare expression occurs in a deferred-freezing
context (e.g., within the default value for a discriminant or for a formal
parameter, or within the expression of an expression function), the compiler
generates a bugbox.

gcc/ada/

* sem_ch3.adb
(Analyze_Object_Declaration): Do not perform expansion actions if
In_Spec_Expression is true.

ada: Minor consistency tweaks in Sem_Ch4

This ensures that, during the analysis of the qualified expressions, type
conversions and unchecked type conversions, the determination of the type
of the node and the analysis of its expression are done in the same order.

No functional changes.

gcc/ada/

* sem_ch4.adb (Analyze_Qualified_Expression): Analyze the
expression only after setting the type.
(Analyze_Unchecked_Type_Conversion): Likewise.
(Analyze_Short_Circuit): Likewise for the operands.
(Analyze_Type_Conversion): Minor tweaks.
(Analyze_Unchecked_Expression): Likewise.

ada: Remove redundant line in Analyze_Qualified_Expression

The same statement is present a few lines above.

gcc/ada/

* sem_ch4.adb (Analyze_Qualified_Expression): Remove redundant
line.

ada: Preanalyze classwide contracts as spec expressions

Classwide contracts are "spec expressions" as defined in the
documentation in sem.ads. Before this patch, the instances of
classwide contracts that are destined to class conditions merging
were not preanalyzed as spec expressions. That caused preanalysis to
emit spurious errors in some cases.

gcc/ada/

* contracts.adb (Preanalyze_Condition): Use
Preanalyze_Spec_Expression.

ada: Fix expansion of 'Wide_Image and 'Wide_Wide_Image on composite types

Attributes Wide_Image and Wide_Wide_Image applied to composite types are
now expanded just like attribute Image.

gcc/ada/

* exp_imgv.adb
(Expand_Wide_Image_Attribute): Handle just like attribute Image.
(Expand_Wide_Wide_Image_Attribute): Likewise.
* exp_put_image.adb
(Build_Image_Call): Adapt to also work for Wide and Wide_Wide
attributes.
* exp_put_image.ads
(Build_Image_Call): Update comment.
* rtsfind.ads
(RE_Id): Support wide variants of Get.
(RE_Unit_Table): Likewise.

ada: Fix inconsistent whitespace in Ada.Numerics.Generic_Complex_Arrays

Cleanup only.

gcc/ada/

* libgnat/a-ngcoar.ads, libgnat/a-ngcoar.adb: Remove extra spaces.

ada: Remove unneeded code in handling formal type defaults

Unneeded code found while experimenting with improved detection of
unreferenced objects.

gcc/ada/

* sem_ch12.adb (Validate_Formal_Type_Default): Remove call to
Collect_Interfaces, which had no effect apart from populating a
list that was not used; fix style.

ada: Cleanup local variable that is only set as an out parameter

Minor improvements; found experimenting with improved detection of
unreferenced objects.

gcc/ada/

* exp_spark.adb (SPARK_Freeze_Type): Refine type of a local
object.
* sem_ch3.adb (Derive_Subprograms): Remove initial value for
New_Subp, which is in only written as an out parameter and never
read.

ada: Remove obsolete code in Resolve_If_Expression

gcc/ada/

* sem_res.adb (Resolve_If_Expression): Remove obsolete special
case.
