switch expansion: limit JT growth param values

Currently, one can request a huge jump table creation which

tree-optimization/108352 - FSM threads creating irreducible loops

The following relaxes a heuristic that prevents creating irreducible
loops from FSM threads not covering multi-way branches.  Instead of
allowing threads that adhere to

      && (n_insns * (unsigned) param_fsm_scale_path_stmts
          > (m_path.length () *
             (unsigned) param_fsm_scale_path_blocks))

with reasoning "We also consider it worth creating an irreducible inner loop if
the number of copied statement is low relative to the length of the path --
in that case there's little the traditional loop optimizer would have done
anyway, so an irreducible loop is not so bad." that I cannot make much
sense of the following patch changes that to only allow those after
loop optimization and when they are (scaled) short:

      && (!(cfun->curr_properties & PROP_loop_opts_done)
          || (m_n_insns * param_fsm_scale_path_stmts
              >= param_max_jump_thread_duplication_stmts)))

This allows us to get rid of --param fsm-scale-path-blocks which
previous to the bisected revision allowed an enlarged path covering
the original allowance (but we do not consider that enlarged path

fortran: Fix up function types for realloc and sincos{,f,l} builtins [PR108349]

As reported in the PR, the FUNCTION_TYPE for __builtin_realloc in the
Fortran FE is wrong since r0-100026-gb64fca63690ad which changed
-  tmp = tree_cons (NULL_TREE, pvoid_type_node, void_list_node);
-  tmp = tree_cons (NULL_TREE, size_type_node, tmp);
-  ftype = build_function_type (pvoid_type_node, tmp);
+  ftype = build_function_type_list (pvoid_type_node,
+                                    size_type_node, pvoid_type_node,
+                                    NULL_TREE);
   gfc_define_builtin ("__builtin_realloc", ftype, BUILT_IN_REALLOC,
                      "realloc", false);
The return type is correct, void *, but the first argument should be
void * too and only second one size_t, while the above change changed
realloc to be void *__builtin_realloc (size_t, void *);
I went through all other changes from that commit and found that
__builtin_sincos{,f,l} got broken as well, instead of the former
void __builtin_sincos{,f,l} (ftype, ftype *, ftype *);
where ftype is {double,float,long double} it is now incorrectly

ipa: Sort ipa_param_body_adjustments::m_replacements (PR 108110)

The problem in PR 108110 is that elements describing the same base
parameter in ipa_param_body_adjustments::m_replacements are not
adjacent to each other, which is something that
ipa_param_body_adjustments::modify_call_stmt when it gathers all
replacements for a parameter.

One option would be to simply always keep looking until the end of the
vector (see bugzilla comment 15 for a one-line fix) but the correct
thing to do is to keep the elements of the vector sorted and thus make
such elements adjacent again.  This patch does that and then also
modifies the look-ups to take advantage of it.

Since the one user of ipa_param_body_adjustments that is not
tree-inline.cc, which is OpenMP declare SIMD cloning code, also
registers its own replacements and in theory pointers to elements of
the m_replacements vector can leak through public method
get_expr_replacement, I decided that in those cases it is the
responsibility of the user of the class to call the sorting method
between the replacement registrations and the first lookup.  That is
why the patch also adds a line to omp-simd-clone.cc.

arithmetic on size_t values promotes to int. Rewrite the constraint
exactly as written in the standard, which works correctly.

libstdc++-v3/ChangeLog:

PR libstdc++/108221
* include/std/span (span::span()): Un-simplify constraint to
work for size_t of lesser rank than int.

IBM zSystems: Make -fcall-saved-... work.

gcc/ChangeLog:

* config/s390/s390.cc (s390_register_info): Check call_used_regs
instead of hard-coding the register numbers for call saved
registers.
(s390_optimize_register_info): Likewise.

gcc/testsuite/ChangeLog:

* gcc.target/s390/fcall-saved.c: New test.

Daily bump.

Modula-2: fix documentation layout

The Modula-2 documentation is rejected by older versions of Makeinfo because
the web of @node markers is fairly broken, apparently some subsections were
moved around, most notably between the Overview and Using sections, and the
@node markers were not (properly) adjusted.

gcc/
* doc/gm2.texi (Overview): Fix @node markers.
(Using): Likewise.  Remove subsections that were moved to Overview
from the menu and move others around.

c++: Only do maybe_init_list_as_range optimization if !processing_template_decl [PR108047]

The last testcase in this patch ICEs, because
maybe_init_list_as_range -> maybe_init_list_as_array
calls maybe_constant_init in:
  /* Don't do this if the conversion would be constant.  */
  first = maybe_constant_init (first);
  if (TREE_CONSTANT (first))
    return NULL_TREE;
but maybe_constant_init shouldn't be called when processing_template_decl.
While we could replace that call with fold_non_dependent_init, my limited
understanding is that this is an optimization and even if we don't optimize
it when processing_template_decl, build_user_type_conversion_1 will be
called again during instantiation with !processing_template_decl if it is
every instantiated and we can do the optimization only then.

c: Check for modifiable static compound literals in inline definitions

The C rule against modifiable objects with static storage duration in
inline definitions should apply to compound literals (using the C2x
feature of storage-class specifiers for compound literals) just as to

ada: Simplify finalization of temporaries created for interface objects

The expansion of (class-wide) interface objects generates a temporary that
holds the actual data and the objects are rewritten as the renaming of the
dereference at the interface tag present in it. These temporaries may need
to be finalized and this is currently done through the renamings, by using
pattern matching to recognize the original source constructs.

Now these temporaries may also need to be adjusted and this is currently
done "naturally", i.e. by using the standard machinery for them, so there
is no fundamental reason why the finalization cannot be done this way too.

Therefore this changes removes the special machinery implemented for their
finalization and let them be handled by the standard one instead.

The problem is mismatch between the caller and callee side.
On the callee side, we do:
  /* NAMED_ARG is a misnomer.  We really mean 'non-variadic'. */
  if (!cfun->stdarg)
    data->arg.named = 1;  /* No variadic parms.  */
  else if (DECL_CHAIN (parm))
    data->arg.named = 1;  /* Not the last non-variadic parm. */
  else if (targetm.calls.strict_argument_naming (all->args_so_far))
    data->arg.named = 1;  /* Only variadic ones are unnamed.  */
  else
    data->arg.named = 0;  /* Treat as variadic.  */
which is later passed to the target hooks to determine if a particular
argument is named or not.  Now, cfun->stdarg is determined from the stdarg_p
call, which for the new C2X TYPE_NO_NAMED_ARGS_STDARG_P function types
(rettype fn (...)) returns true.  Such functions have no named arguments,
so data->arg.named will be 0 in function.cc.  But on the caller side,
as TYPE_NO_NAMED_ARGS_STDARG_P function types have TYPE_ARG_TYPES NULL,

xtensa: Optimize bitwise splicing operation

This patch optimizes the operation of cutting and splicing two register
values at a specified bit position, in other words, combining (bitwise
ORing) bits 0 through (C-1) of the register with bits C through 31

Abstract the atomic counter used to synchronize access to time_zone

instead of atomic<int_least32_t>, as that should be the most efficient

The new API allows the calling code to be simpler, without needing to
repeat the same error prone preprocessor conditions in multiple places.
It also allows using template metaprogramming to decide whether to use
the atomic or a mutex, which gives us more flexibility than only using
preprocessor conditions. That allows us to choose the mutex

c: C2x semantics for __builtin_tgmath

__builtin_tgmath implements <tgmath.h> semantics for integer generic
arguments that handle cases involving _FloatN / _FloatNx types as
specified in TS 18661-3 plus some defect fixes.

C2x has further changes to the semantics for <tgmath.h> macros with
such types, which should also be considered defect fixes (although
handled through the integration of TS 18661-3 in C2x rather than
through an issue tracking process).  Specifically, the rules were
changed because of problems raised with using the macros with the
evaluation format types such as float_t and _Float32_t: the older
version of the rules didn't allow passing _FloatN / _FloatNx types to
the narrowing macros returning float or double, or passing float /
double / long double to the narrowing macros returning _FloatN /
_FloatNx, which was a problem with the evaluation format types which
could be either kind of type depending on the value of
FLT_EVAL_METHOD.

Thus the new rules allow cases of mixing types which were not allowed
before - which is not itself a problem for __builtin_tgmath - and, as
part of the changes, the handling of integer arguments was also
changed: if there is any _FloatNx generic argument, integer generic
arguments are treated as _Float32x (not double), while the rule about
treating integer arguments to narrowing macros returning _FloatN or
_FloatNx as _Float64 not double was removed (no longer needed now
double is a valid argument to such macros).

Implement the changes for __builtin_tgmath.  (The changes also added a
rule that if any argument is _DecimalNx, integer arguments are treated
as _Decimal64x, but GCC doesn't support _DecimalNx types so nothing is
done about that.)

I have a corresponding glibc patch to update glibc test expectations
for C2x and also ensure that appropriate semantics are followed when
GCC 7 through 12 are used with <tgmath.h> (avoiding __builtin_tgmath
in cases where it doesn't match the C2x semantics).

libstdc++: Fix deadlock in debug iterator increment [PR108288]

With -fno-elide-constructors the debug iterator post-increment and
post-decrement operators are susceptible to deadlock. They take a mutex
lock and then return a temporary, which also attempts to take a lock to
attach itself to the sequence. If the return value and *this happen to
collide and use the same mutex from the pool, then you get a deadlock
trying to lock a mutex that is already held by the current thread.

The solution is to construct the return value before taking the lock.
The copy constructor and pre-inc/pre-dec operators already manage locks
correctly, without deadlock, so just implement post-inc/post-dec in the
conventional way, taking a copy then modifying *this, then returning the
copy.

c++: class-head parsing and CPP_TEMPLATE_ID access [PR108275]

When tentatively parsing what is really an elaborated-type-specifier
containing a template-id first as a class-specifier, we may form a
CPP_TEMPLATE_ID token that later gets reused by the fallback parse if
the tentative parse fails.  These special tokens also capture the access
checks that have been deferred while parsing the template-id.  But here
we form such a token when the access check state is dk_no_check, and so
the token captures no access checks.  This effectively bypasses access
checking for the template-id during the subsequent parse as an
elaborated-type-specifier.

modula-2: Remove uses of scalb*() and significand*() [PR107631]

The scalb*() functions are obsolete in Posix from 2004 and removed in
2008.

The significand*() functions are glibc-only and considered there to be
obsolescent (not supported for types such as _Float128).

We can remove them from Modula-2 since they are not required for ISO
support, but we need to provide an implementation of significand* for
the "fraction()" functions.

This patch reverts a special-case related to inlining of renamed bodies
