This adds the capability to value-numbering of treating complex
address expressions where the offset becomes invariant as equal
to a POINTER_PLUS_EXPR. This restores CSE that is now prevented
by early lowering of &MEM[ptr + CST] to a POINTER_PLUS_EXPR.
Unfortunately this regresses gcc.dg/asan/pr99673.c again, so
the testcase is adjusted accordingly.

Although the automated regression testing scripts for powerpc64 appear
to be somewhat garbled at the moment, they've correctly identified that
my new test case for pr102950.c is failing on powerpc64, as char by
default is unsigned on this target. This patch tweaks the new testcase
by explicitly using "signed char" so that it's testing the intended EVRP
behaviour portably. Committed as obvious.

The following removes the indirection to real_value from REAL_CST
which doesn't seem to serve any useful purpose. Any sharing can
be achieved by sharing the actual REAL_CST (which is what usually
happens when copying trees) and sharing of real_value amongst
different REAL_CST doesn't happen as far as I can see and would
only lead to further issues like mismatching type and real_value.

In my previous PR104470 patch I added yet another place that needs to handle
dependent member rewriting for deduction guides; this patches centralizes
rewriting into maybe_dependent_member_ref. tsubst_baselink still has its

Here we're crashing from maybe_aggr_guide ultimately because
processing_template_decl isn't set when partially instantiating the

When g++ emits
warning: overflow in conversion from 'int' to 'char' changes value from '300' to '',''
for code like "char c = 300;" it might raise a few eyebrows. With this

the numerical value, so convert constants of type char to int. It looks

Consider
struct F {
F(int) {}
F operator()(int) const { return *this; }
};
and
F(i)(0)(0);
where we're supposed to first call the constructor and then invoke
the operator() twice. However, we parse this as an init-declarator:
"(i)" looks like a perfectly valid declarator, then we see an '(' and
think it must be an initializer, so we commit and we're toast. My
fix is to look a little bit farther before deciding we've seen an
initializer.
This is only a half of c++/64679, the other part of the PR is unrelated:
there the problem is that we are calling pushdecl while parsing
tentatively (in cp_parser_parameter_declaration_list), which is bad.

This patch fixes an oversight whereby we treated >= as the end of
a template argument. This causes problems in C++14, because in
cp_parser_template_argument we go different ways for C++14 and C++17:
/* It must be a non-type argument. In C++17 any constant-expression is
allowed. */
if (cxx_dialect > cxx14)
goto general_expr;
so in this testcase in C++14 we get "N" as the template argument but in
C++17 it is the whole "N >= 5" expression. So in C++14 the remaining
">= 5" triggered the newly-added diagnostic.

When pattern recognition fails to sanitize all defs of a mask
producing operation and the respective def is external or constant
we end up trying to produce a VECTOR_BOOLEAN_TYPE_P constructor
which in turn ends up exposing stmts like
<signed-boolean:1> _135 = _49 ? -1 : 0;
which isn't handled well in followup SLP and generates awful code.
We do rely heavily on pattern recognition to sanitize mask vs.
data uses of bools but that fails here which means we also should
fail vectorization. That avoids ICEing because of such stmts
and it also avoids generating weird code which makes the
vectorization not profitable.
The following patch simply disallows external VECTOR_BOOLEAN_TYPE_P
defs and arranges the promote to external code to instead promote
mask uses to extern (that's just a short-cut here).
I've also looked at aarch64 and with SVE and a fixed vector length
for the gcc.target/i386/pr101636.c testcase. I see similar vectorization
(using <signed-boolean:4>) there but it's hard to decide whether the
old, the new or no vectorization is better for this. The code
generated with traditional integer masks isn't as awkward but we
still get the != 0 promotion done for each scalar element which
doesn't look like intended - this operation should be visible upfront.
That also means some cases will now become a missed optimization
that needs to be fixed by bool pattern recognition. But that can
possibly be delayed to GCC 13.

The testcase shows that we can end up with a contiguous access across
loop iterations but by means of permutations the elements accessed
might only cover parts of a vector. In this case we end up with
GROUP_GAP == 0 but still need to avoid accessing excess elements
in the last loop iterations. Peeling for gaps is designed to cover
this but a single scalar iteration might not cover all of the excess
elements. The following ensures peeling for gaps is done in this
situation and when that isn't sufficient because we need to peel
more than one iteration (gcc.dg/vect/pr103116-2.c), fail the SLP
vectorization.

Somebody complained on IRC that when writing a new backend one can get
an error while compiling build/gencondmd.cc.
The problem is that when host compiler is g++ 3 or later (or when
bootstrapping), we compile it with g++ -std=c++11 -pedantic and
the generated insn_conditions array contains pairs
{ "cond", __builtin_constant_p (cond) ? (int) (cond) : -1 },
where cond is some non-trivial instruction condition. Now if a target
uses "" for all the conditions (admittedly unlikely for non-trivial
target), the initializer for insn_conditions[] is {} and that is
pedantically rejected because C++ doesn't support zero-sized arrays.
The following patch fixes that by adding an artificial termination
element and skips that during the walk.

On the following testcase, we emit deprecated warnings or unavailable errors

requires operator int, no?

This patch fixes PR tree-optimization/102950, which is a P2 regression,
by providing better range bounds for BIT_XOR_EXPR, BIT_AND_EXPR and
BIT_IOR_EXPR on signed integer types. In general terms, any binary
bitwise operation on sign-extended or zero-extended integer types will
produce results that are themselves sign-extended or zero-extended.
More precisely, we can derive signed bounds from the number of leading
redundant sign bit copies, from the equation:
clrsb(X op Y) >= min (clrsb (X), clrsb(Y))
and from the property that for any (signed or unsigned) range [lb, ub]
that clrsb([lb, ub]) >= min (clrsb(lb), clrsb(ub)).
These can be used to show that [-1, 0] op [-1, 0] is [-1, 0] or that
[-128, 127] op [-128, 127] is [-128, 127], even when tracking nonzero
bits would result in VARYING (as every bit can be 0 or 1). This is
equivalent to determining the minimum type precision in which the
operation can be performed then sign extending the result.
One additional refinement is to observe that X ^ Y can never be
zero if the ranges of X and Y don't overlap, i.e. X can't be equal
to Y.
Previously, the expression "(int)(char)a ^ 233" in the PR was considered
VARYING, but with the above changes now has the range [-256, -1][1, 255],
which is sufficient to optimize away the call to foo.

gcc.dg/vect/costmodel/ppc/costmodel-vect-31a.c covers ppc variants
that accept and reject misaligned accesses. The message that it
expects for rejection was removed in the gcc-11 development cycle by
commit r11-1969. The patch adjusted multiple tests to use the message
introduced in r11-1945, but missed this one.
for gcc/testsuite/ChangeLog
* gcc.dg/vect/costmodel/ppc/costmodel-vect-31a.c: Update
the expected message for the case in which unaligned accesses
are not allowed.

On PR102629 I noticed that we were giving the entire lambda as the location
for this template-id.
gcc/cp/ChangeLog:
* pt.cc (tsubst_copy_and_build) [TEMPLATE_ID_EXPR]: Copy location.
(do_auto_deduction): Use expr location.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/lambda-pack-init7.C: Check column number.

While looking at PR96645 I noticed that while we were diagnosing names
changing meaning in the full class context, we weren't doing this for
lookups in nested class bodies.
Note that this breaks current range-v3; I've submitted a pull request to fix
its violation of the rule.
gcc/cp/ChangeLog:
* class.cc (maybe_note_name_used_in_class): Note in all enclosing
classes. Remember location of use.
(note_name_declared_in_class): Adjust.
gcc/testsuite/ChangeLog:
* g++.dg/lookup/name-clash13.C: New test.
* g++.dg/lookup/name-clash14.C: New test.
* g++.dg/lookup/name-clash15.C: New test.
* g++.dg/lookup/name-clash16.C: New test.
