c++: Avoid incorrect shortening of divisions [PR108365]

The following testcase is miscompiled, because we shorten the division
in a case where it should not be shortened.
Divisions (and modulos) can be shortened if it is unsigned division/modulo,
or if it is signed division/modulo where we can prove the dividend will
not be the minimum signed value or divisor will not be -1, because e.g.
on sizeof(long long)==sizeof(int)*2 && __INT_MAX__ == 0x7fffffff targets
(-2147483647 - 1) / -1 is UB
but
(int) (-2147483648LL / -1LL) is not, it is -2147483648.
The primary aim of both the C and C++ FE division/modulo shortening I assume
was for the implicit integral promotions of {,signed,unsigned} {char,short}
and because at this point we have no VRP information etc., the shortening
is done if the integral promotion is from unsigned type for the divisor
or if the dividend is an integer constant other than -1.
This works fine for char/short -> int promotions when char/short have
smaller precision than int - unsigned char -> int or unsigned short -> int
will always be a positive int, so never the most negative.

Now, the C FE checks whether orig_op0 is TYPE_UNSIGNED where op0 is either
the same as orig_op0 or that promoted to int, I think that works fine,
if it isn't promoted, either the division/modulo common type will have the
same precision as op0 but then the division/modulo is unsigned and so
without UB, or it will be done in wider precision (e.g. because op1 has
wider precision), but then op0 can't be minimum signed value.  Or it has
been promoted to int, but in that case it was again from narrower type and
so never minimum signed int.

But the C++ FE was checking if op0 is a NOP_EXPR from TYPE_UNSIGNED.
First of all, not sure if the operand of NOP_EXPR couldn't be non-integral
type where TYPE_UNSIGNED wouldn't be meaningful, but more importantly,
even if it is a cast from unsigned integral type, we only know it can't be
minimum signed value if it is a widening cast, if it is same precision or
narrowing cast, we know nothing.

So, the following patch for the NOP_EXPR cases checks just in case that
it is from integral type and more importantly checks it is a widening
conversion, and then next to it also allows op0 to be just unsigned,
promoted or not, as that is what the C FE will do for those cases too
and I believe it must work - either the division/modulo common type
will be that unsigned type, then we can shorten and don't need to worry
about UB, or it will be some wider signed type but then it can't be most
negative value of the wider type.
And changes both the C and C++ FEs to do the same thing, using a helper
function in c-family.

hash table: enforce testing is_empty before is_deleted

Existing hash_table traits that use the same representation for empty
and deleted slots reject marking slots as deleted, and to not pass
is_deleted for slots that pass is_empty.

Nevertheless, nearly everywhere, we only test for is_deleted after
checking that !is_empty first.  The one exception was the copy
constructor, that would fail if traits recognized is_empty slots as
is_deleted, but then refused to mark_deleted.

This asymmetry is neither necessary nor desirable, and there is a
theoretical risk that traits might not only fail to refuse to
mark_deleted, but also return is_deleted for is_empty slots.

This patch introduces checks that detect these potentially problematic
situations, and reorders the tests in the copy constructor so as to
use the conventional testing order and thus avoid them.

sched-deps: do not schedule pseudos across calls [PR108117]

Scheduling across calls in the pre-RA scheduler is problematic: we do
not take liveness info into account, and are thus prone to extending
lifetime of a pseudo over the loop, requiring a callee-saved hardreg
or causing a spill.

If current function called a setjmp, lifting an assignment over a call
may be incorrect if a longjmp would happen before the assignment.

convert_like_internal is there called with type of double and

convert_and_check with the EXCESS_PRECISION_EXPR expression rather

libstdc++: Fix unintended layout change to std::basic_filebuf [PR108331]

GCC 13 has a new implementation of gthr-win32.h which supports C++11
mutexes, threads etc. but this causes an unintended ABI break. The
__gthread_mutex_t type is always used in std::basic_filebuf even in
C++98, so independent of whether C++11 sync primitives work or not.
Because that type changed for the win32 thread model, we have a layout
change in std::basic_filebuf. The member is completely unused, it just
gets passed to the std::__basic_file constructor and ignored. So we
don't need that mutex to actually work, we just need its layout to not
change.

Introduce a new __gthr_win32_legacy_mutex_t struct in gthr-win32.h with
the old layout, and conditionally use that in std::basic_filebuf.

aarch64: Fix DWARF frame register sizes for predicates

Jakub pointed out that __builtin_init_dwarf_reg_size_table
set the size of predicate registers to their current runtime
size when compiled with +sve, but to 8 bytes otherwise.
As explained in the comment, both behaviours are wrong.
Predicates change size with VL and should never need to be
restored during unwinding.

In contrast, the call-saved FP&SIMD frame registers are 8 bytes
(even though the hardware registers are at least 16 bytes) and
the call-clobbered registers have zero size.  A zero size seems

PR tree-optimization/92342: Optimize b & -(a==c) in match.pd

This patch is an update/tweak of Andrew Pinski's two patches for
PR tree-optimization/92342, that were originally posted by in November:
https://gcc.gnu.org/pipermail/gcc-patches/2021-November/585111.html
https://gcc.gnu.org/pipermail/gcc-patches/2021-November/585112.html

Technically, the first of those was approved by Richard Biener, though
never committed, and my first thought was to simply push it for Andrew,
but the review of the second piece expressed concerns over comparisons
in non-integral modes, where the result may not be zero-one valued.
Indeed both transformations misbehave in the presence of vector mode
comparisons (these transformations are already implemented for
vec_cond elsewhere in match.pd), so my minor contribution is to limit
these new transformations to scalars, by testing that both the operands
and results are INTEGRAL_TYPE_P.

aarch64: Fix bit-field alignment in param passing [PR105549]

While working on enabling DFP for AArch64, I noticed new failures in
gcc.dg/compat/struct-layout-1.exp (t028) which were not actually
caused by DFP types handling. These tests are generated during 'make
check' and enabling DFP made generation different (not sure if new
non-DFP tests are generated, or if existing ones are generated
differently, the tests in question are huge and difficult to compare).

Anyway, I reduced the problem to what I attach at the end of the new
gcc.target/aarch64/aapcs64/va_arg-17.c test and rewrote it in the same
scheme as other va_arg* AArch64 tests.  Richard Sandiford further
reduced this to a non-vararg function, added as a second testcase.

This is a tough case mixing bit-fields and alignment, where
aarch64_function_arg_alignment did not follow what its descriptive
comment says: we want to use the natural alignment of the bit-field
type only if the user didn't reduce the alignment for the bit-field
itself.

The patch also adds a comment and assert that would help someone who
has to look at this area again.

The fix would be very small, except that this introduces a new ABI
break, and we have to warn about that.  Since this actually fixes a
problem introduced in GCC 9.1, we keep the old computation to detect
when we now behave differently.

This patch adds two new tests (va_arg-17.c and
pr105549.c). va_arg-17.c contains the reduced offending testcase from
struct-layout-1.exp for reference.  We update some tests introduced by
the previous patch, where parameters with bit-fields and packed
attribute now emit a different warning.

aarch64: fix warning emission for ABI break since GCC 9.1

While looking at PR 105549, which is about fixing the ABI break
introduced in GCC 9.1 in parameter alignment with bit-fields, we
noticed that the GCC 9.1 warning is not emitted in all the cases where
it should be.  This patch fixes that and the next patch in the series
fixes the GCC 9.1 break.

We split this into two patches since patch #2 introduces a new ABI
break starting with GCC 13.1.  This way, patch #1 can be back-ported
to release branches if needed to fix the GCC 9.1 warning issue.

The main idea is to add a new global boolean that indicates whether
we're expanding the start of a function, so that aarch64_layout_arg
can emit warnings for callees as well as callers.  This removes the
need for aarch64_function_arg_boundary to warn (with its incomplete
information).  However, in the first patch there are still cases where
we emit warnings were we should not; this is fixed in patch #2 where
we can distinguish between GCC 9.1 and GCC.13.1 ABI breaks properly.

The fix in aarch64_function_arg_boundary (replacing & with &&) looks
like an oversight of a previous commit in this area which changed
'abi_break' from a boolean to an integer.

We also take the opportunity to fix the comment above
aarch64_function_arg_alignment since the value of the abi_break
parameter was changed in a previous commit, no longer matching the
description.

into a shape likened by the vectorizer.  Nowadays the rank compute
produces correct association for reduction chains and the vectorizer
has robust support to fall back to a regular reductions (via
reduction path) when it turns out to be not a proper reduction chain.

So this patch removes the special code in reassoc which makes
the TSVC s352 vectorized with -Ofast (it is already without
-ffast-math).

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.

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

tree-optimization/106293 - missed DSE with virtual LC PHI

Degenerate virtual PHIs can break DSEs fragile heuristic as to what

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.

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:

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

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,
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.
