9ca4899144 preprocessor: Don't register pragmas in directives-only mode [PR108244] 
libcpp's directives-only mode does not expect deferred pragmas to be
registered, but to date the c-family registration process has not checked for
this case. That issue became more visible since r13-1544, which added the
commonly used GCC diagnostic pragmas to the set of those registered in
preprocessing modes. Fix it by checking for directives-only mode in
c-family/c-pragma.cc.

gcc/c-family/ChangeLog:

	PR preprocessor/108244
	* c-pragma.cc (c_register_pragma_1): Don't attempt to register any
	deferred pragmas if -fdirectives-only.
	(init_pragma): Likewise.

688fc162b7 analyzer: fix leak false positives on "*UNKNOWN = PTR;" [PR108252] 
PR analyzer/108252 reports a false positive from -Wanalyzer-malloc-leak on
code like this:

  *ptr_ptr = strdup(EXPR);

where ptr_ptr is an UNKNOWN_VALUE.

When we handle:
  *UNKNOWN = PTR;
store::set_value normally marks *PTR as having escaped, and this means
we don't report PTR as leaking when the last usage of PTR is lost.

However this only works for cases where PTR is a region_svalue.
In the example in the bug, it's a conjured_svalue, rather than a
region_svalue.  A similar problem can arise for FDs, which aren't
pointers.

This patch fixes the bug by updating store::set_value to mark any
values stored via *UNKNOWN = VAL as not leaking.

Additionally, sm-malloc.cc's known_allocator_p hardcodes strdup and
strndup as allocators (and thus transitioning their result to
"unchecked"), but we don't implement known_functions for these, leading
to the LHS being a CONJURED_SVALUE, rather than a region_svalue to a
heap-allocated region.  A similar issue happens with functions marked
with __attribute__((malloc)).  As part of a "belt and braces" fix, the
patch also updates the handling of these functions, so that they use
heap-allocated regions.

gcc/analyzer/ChangeLog:
	PR analyzer/108252
	* kf.cc (class kf_strdup): New.
	(class kf_strndup): New.
	(register_known_functions): Register them.
	* region-model.cc (region_model::on_call_pre): Use
	&HEAP_ALLOCATED_REGION for the default result of an external
	function with the "malloc" attribute, rather than CONJURED_SVALUE.
	(region_model::get_or_create_region_for_heap_alloc): Allow
	"size_in_bytes" to be NULL.
	* store.cc (store::set_value): When handling *UNKNOWN = VAL,
	mark VAL as "maybe bound".

23b4ce1837 c: Don't emit DEBUG_BEGIN_STMTs for K&R function argument declarations [PR105972] 
K&R function parameter declarations are handled by calling
recursively c_parser_declaration_or_fndef in a loop, where each such
call will add_debug_begin_stmt at the start.
Now, if the K&R function definition is not a nested function,
building_stmt_list_p () is false and so we don't emit the DEBUG_BEGIN_STMTs
anywhere, but if it is a nested function, we emit it in the containing
function at the point of the nested function definition.
As the following testcase shows, it can cause ICEs if the containing
function has var-tracking disabled but nested function has them enabled,
as the DEBUG_BEGIN_STMTs are added to the containing function which
shouldn't have them but MAY_HAVE_DEBUG_MARKER_STMTS is checked already
for the nested function, or just wrong experience in the debugger.

The following patch ensures we don't emit any such DEBUG_BEGIN_STMTs for the
K&R function parameter declarations even in nested functions.

	PR c/105972
	* c-parser.cc (c_parser_declaration_or_fndef): Disable debug non-bind
	markers for K&R function parameter declarations of nested functions.

98837d6e79 PR tree-optimization/71343: Value number X<<2 as X*4. 
This patch is the second part of a fix for PR tree-optimization/71343,
that implements Richard Biener's suggestion of using tree-ssa's value
numbering instead of match.pd.  The change is that when assigning a
value number for the expression X<<C, we actually look-up or insert
the value number for the multiplication X*(1<<C).  This elegantly
handles the fact that we (intentionally) don't canonicalize these as
equivalent in GIMPLE, and the optimization/equivalence in PR 71343 now
happens by (tree-ssa SCCVN) magic.

When testing one patch which adds a fortran test case into

immediately if the testing target isn't a PowerPC target.

6224db0e4d rs6000: Make P10_FUSION honour tuning setting 
We noticed this issue when Segher reviewed the patch for
PR104024.  When there is no explicit setting for option
-mpower10-fusion, we enable OPTION_MASK_P10_FUSION for
TARGET_POWER10.  But it's not right, it should honour
tuning setting instead.

This patch is to fix it accordingly, it's bootstrapped
, and regtested on powerpc64-linux-gnu P8 and
powerpc64le-linux-gnu P9.

But on powerpc64le-linux-gnu P10 it had one regression
failure against the test case gcc.target/powerpc/pr105586.c.
I looked into it and confirmed that a latent bug was
exposed and filed one separated bug PR108273 instead.

gcc/ChangeLog:

	* config/rs6000/rs6000.cc (rs6000_option_override_internal): Make
	OPTION_MASK_P10_FUSION implicit setting honour Power10 tuning setting.

7c9f20fcfd 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
now because enlarging it doesn't add any information).

0986c351aa 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
void __builtin_sincos{,f,l} (ftype *, ftype *);

The following patch fixes that, plus some formatting issues around
the spots I've changed.

b399afd22c xtensa: Make instruction cost estimation for size more accurate

4e0b504f26 tree-optimization/106293 - missed DSE with virtual LC PHI 
Degenerate virtual PHIs can break DSEs fragile heuristic as to what
defs it can handle for further processing.  The following enhances
it to look through degenerate PHIs by means of a worklist, processing
the degenerate PHI defs uses to the defs array.  The rewrite of
virtuals into loop-closed SSA caused this to issue appear more often.
The patch itself is mostly re-indenting the new loop body.

	process degenerate PHI defs.

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.

01ea66a6c5 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.

d4eaf83d6e 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.

-FAIL: gcc.dg/torture/c2x-stdarg-split-1a.c   -Os  execution test
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,
we instead treat those calls as unprototyped even when they are prototyped
- /* If we know nothing, treat all args as named.  */ n_named_args = num_actuals;
in 2 spots.  We need to treat the TYPE_NO_NAMED_ARGS_STDARG_P cases as
prototyped with no named arguments.

a5a8242153 middle-end/69482 - not preserving volatile accesses 
The following addresses a long standing issue with not preserving
accesses to non-volatile objects through volatile qualified
pointers in the case that object gets expanded to a register.  The
fix is to treat accesses to an object with a volatile qualified
access as forcing that object to memory.  This issue got more
exposed recently so it regressed more since GCC 11.

	PR middle-end/69482
	* cfgexpand.cc (discover_nonconstant_array_refs_r): Volatile
	qualified accesses also force objects to memory.

	* gcc.target/i386/pr69482-1.c: New testcase.
