[testsuite] Fix PR92464 by adjust test case loop bound
The recent vectorization cost adjustment on load leads
the profitable min iteration count to change from 19 to 12.
The case happens to hit the threshold. This patch is to

Support C2x [[]] attributes for C.
This patch adds support for the C2x [[]] attribute syntax to the C
front end. Support is only added for C at this point, not for
Objective-C; I intend to add the unbounded lookahead required to
support it for Objective-C in a followup patch, but maybe not in
development stage 1.
The syntax is supported in all relevant places where the standard says
it is supported, but support is not added for the individual
attributes specified in C2x (all of which are optional to support). I
expect to add support for some of them in followup patches; all except
nodiscard can be mapped directly to the semantics of an existing GNU
attribute (subject to extra checks for invalid usages such as the same
attribute being used more than once inside a single [[]]), and the
fallthrough attribute already works after this patch because of
existing special-case code handling it (but without some of the checks
for invalid usage being present).
Note that the four functions c_token_starts_declspecs,
c_token_starts_declaration, c_parser_next_token_starts_declspecs and
c_parser_next_tokens_start_declaration do *not* accept "[[". This is
analogous with the handling of __extension__: both cases have the
property that they can start either a declaration or some other
statements and so need an unbounded number of tokens to be parsed in
the caller before it can find out what kind of syntactic construct
follows. Note also that, while I updated all places calling those
functions for standard C syntax to handle attributes if applicable, I
did not do anything regarding calls to such functions for OpenMP or
OpenACC constructs. Thus, if there are such constructs using such
functions where "[[" *should* be accepted as a possible start to a
declaration, the code for parsing those constructs should be updated
accordingly.
Although all cases of the syntax are handled, and attributes applied
to the constructs the standard says they should be (with less laxity
than there is for GNU attributes to allow an attribute applied to one
construct to be moved automatically to another one), there is a major
limitation in the existing language-independent code in attribs.c
preventing most cases of type attributes from working. The following
code has been present with minor changes since the first support for
[[]] attributes for C++ was added:
if (TYPE_P (*node)
&& cxx11_attr_p
&& !(flags & ATTR_FLAG_TYPE_IN_PLACE))
{
/* This is a c++11 attribute that appertains to a
type-specifier, outside of the definition of, a class
type. Ignore it. */
auto_diagnostic_group d;
if (warning (OPT_Wattributes, "attribute ignored"))
inform (input_location,
"an attribute that appertains to a type-specifier "
"is ignored");
continue;
}
I see no justification for this in general for either C or C++ and so
propose to remove or restrict it in a followup bug-fix patch. Both C
and C++ are clear about attributes in certain places (at the end of
declaration specifiers, or after function or array declarators)
appertaining to a specific type (and explicitly say, in the case of
attributes at the end of declaration specifiers, that they only apply
for that particular use of that type, not for subsequent uses of the
same type without the attributes). Thus it seems clear to me that,
for example,
int [[gnu::mode(DI)]] x;
ought to be accepted as an analogue in [[]] syntax for
int __attribute__((mode(DI))) x;
(or strictly as an analogue for a version of that with extra
parentheses to make the GNU attribute bind properly to the type rather
than being automatically moved from the declaration to the type).
There are certain cases where an attribute *does* only make sense for
the definition of a type (e.g. "packed" on structure types), but those
should already be handled in the individual attribute handlers (such
as handle_packed_attribute, which already has code to deal with that
issue). So my inclination is that the above-quoted check in attribs.c
should simply be removed, but failing that it should be restricted to
structure and union types (and such a change would be a bug-fix).
That would then allow various cases of [[]] attributes on types to
work properly.

Sanitize the constant argument for rotr<mode>3
This was dormant for quite some time, but it started happening for me
on gcc.c-torture/compile/pr65153.c sometime after r276645 for -mabi=32 linux runs.
The pattern accepts any SMALL_OPERAND constant value while it asserts during the final
that the value is in the mode size range. I this case it happens that combine_and_move_insns
during ira makes a pattern with negative "shift count" which fails at final stage.
This simple fix just truncates the constant operand to mode size the same as shift patterns.

Add C2x *_NORM_MAX constants to <float.h>.
C2x adds <float.h> constants FLT_NORM_MAX, DBL_NORM_MAX and

floating-point number, where the given definition of normalized is
that all possible values with MANT_DIG significand digits (leading one
not zero) can be represented with that exponent. The effect of that
definition is that these macros are the same as the corresponding MAX

Avoid accounting for non-existent vector loop versioning
vect_analyze_loop_costing uses two profitability thresholds: a runtime
one and a static compile-time one. The runtime one is simply the point
at which the vector loop is cheaper than the scalar loop, while the
static one also takes into account the cost of choosing between the
scalar and vector loops at runtime. We compare this static cost against
the expected execution frequency to decide whether it's worth generating
any vector code at all.
However, we never reclaimed the cost of applying the runtime threshold
if it turned out that the vector code can always be used. And we only
know whether that's true once we've calculated what the runtime
threshold would be.

is to use "modifier" to distinguish between promotion, demotion,

multiple copies the same cost as a single copy.

[C++] Fix interaction between aka changes and DR1558 (PR92206)
One of the changes in r277281 was to make the typedef variant
handling in strip_typedefs pass the raw DECL_ORIGINAL_TYPE to the
recursive call, instead of applying TYPE_MAIN_VARIANT first.
This PR shows that that interacts badly with the implementation
of DR1558, because we then refuse to strip aliases with dependent
template parameters and trip:
gcc_assert (!typedef_variant_p (result)
|| ((flags & STF_USER_VISIBLE)
&& !user_facing_original_type_p (result)));
Keeping the current behaviour but suppressing the ICE leads to a
duplicate error (the dg-bogus in the first test), so that didn't
seem like a good fix.
I assume keeping the alias should never actually be necessary for
DECL_ORIGINAL_TYPEs, because it will already have been checked
somewhere, even for implicit TYPE_DECLs. This patch therefore
passes a flag to say that we can safely strip aliases with
dependent template parameters.

Free dominance info at the beginning of pass_jump_after_combine
try_forward_edges does not update dominance info, and merge_blocks
relies on it being up-to-date. In PR92430 stale dominance info makes
merge_blocks produce a loop in the dominator tree, which in turn makes
delete_basic_block loop forever.
Fix by freeing dominance info at the beginning of cleanup_cfg.

Add OpenACC 2.6 `serial' construct support
The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard)
is equivalent to a `parallel' construct with clauses `num_gangs(1)
num_workers(1) vector_length(1)' implied.
These clauses are therefore not supported with the `serial'
construct. All the remaining clauses accepted with `parallel' are also
accepted with `serial'.
The `serial' construct is implemented like `parallel', except for
hardcoding dimensions rather than taking them from the relevant
clauses, in `expand_omp_target'.
Separate codes are used to denote the `serial' construct throughout the
middle end, even though the mapping of `serial' to an equivalent
`parallel' construct could have been done in the individual language
frontends. In particular, this allows to distinguish between compute
constructs in warnings, error messages, dumps etc.

Fix SLP downward group access classification (PR92420)
This PR was caused by the SLP handling in get_group_load_store_type
returning VMAT_CONTIGUOUS rather than VMAT_CONTIGUOUS_REVERSE for
downward groups.
A more elaborate fix would be to try to combine the reverse permutation
into SLP_TREE_LOAD_PERMUTATION for loads, but that's really a follow-on
optimisation and not backport material. It might also not necessarily
be a win, if the target supports (say) reversing and odd/even swaps
