arm: correctly handle inequality comparisons against max constants [PR100563]
Normally we expect the gimple optimizers to fold away comparisons that
are always true, but at some lower optimization levels this is not
always the case, so the back-end has to be able to generate correct
code in these cases.
In this example, we have a comparison of the form
(unsigned long long) op <= ~0ULL
which, of course is always true.
Normally, in the arm back-end we handle these expansions where the
immediate cannot be handled directly by adding 1 to the constant and
then adjusting the comparison operator:
(unsigned long long) op < CONST + 1
but we cannot do that when the constant is already the largest value.
Fortunately, we observe that the comparisons we need to handle this
way are either always true or always false, so instead of forming a
comparison against the maximum value, we can replace it with a
comparison against the minimum value (which just happens to also be a
constant we can handle. So
op1 <= ~0ULL -> op1 >= 0U
op1 > ~0ULL -> op1 < 0U
op1 <= LONG_LONG_INT_MAX -> op1 >= (-LONG_LONG_INT_MAX - 1)
op1 > LONG_LONG_INT_MAX -> op1 < (-LONG_LONG_INT_MAX - 1)

ix86: Support V{2, 4}DImode arithmetic right shifts for SSE2+ [PR98856]
As mentioned in the PR, we don't support arithmetic right V2DImode or
V4DImode on x86 without -mavx512vl or -mxop. The ISAs indeed don't have
{,v}psraq instructions until AVX512VL, but we actually can emulate it quite
easily.
One case is arithmetic >> 63, we can just emit {,v}pxor; {,v}pcmpgt for
that for SSE4.2+, or for SSE2 psrad $31; pshufd $0xf5.
Then arithmetic >> by constant > 32, that can be done with {,v}psrad $31
and {,v}psrad $(cst-32) and two operand permutation,
arithmetic >> 32 can be done as {,v}psrad $31 and permutation of that
and the original operand. Arithmetic >> by constant < 32 can be done
as {,v}psrad $cst and {,v}psrlq $cst and two operand permutation.
And arithmetic >> by variable scalar amount can be done as
arithmetic >> 63, logical >> by the amount, << by (64 - amount of the
>> 63 result; note that the vector << 64 result in 0) and oring together.
I had to improve the permutation generation so that it actually handles
the needed permutations (or handles them better).

retry zero-call-used-regs from zeroed regs
default_zero_call_used_regs currently requires all potentially zeroed
registers to offer a move opcode that accepts zero as an operand.
This is not the case e.g. for ARM's r12/ip in Thumb mode, and it was
not the case of FP registers on AArch64 as of GCC 10.
This patch introduces a fallback strategy to zero out registers,
copying from registers that have already been zeroed. Adjacent
sources to make up wider modes are also supported.
This does not guarantee that there will be some zeroed-out register to
use as the source, but it expands the cases in which the default
implementation works out of the box.

The inliner doesn't remap DEBUG_EXPR_DECLs, so the same decls can appear
in multiple functions.
Furthermore, expansion reuses corresponding DEBUG_EXPRs too, so they again
can be reused in multiple functions.
Neither of that is a major problem, DEBUG_EXPRs are just magic value holders
and what value they stand for is independent in each function and driven by
what debug stmts or DEBUG_INSNs they are bound to.
Except for DEBUG_EXPR*s with vector types, TYPE_MODE can be either BLKmode
or some vector mode depending on whether current function's enabled ISAs
support that vector mode or not. On the following testcase, we expand it
first in foo function without AVX2 enabled and so the DEBUG_EXPR is
BLKmode, but later the same DEBUG_EXPR_DECL is used in a simd clone with
AVX2 enabled and expansion ICEs because of a mode mismatch.
The following patch fixes that by forcing recreation of a DEBUG_EXPR if
there is a mode mismatch for vector typed DEBUG_EXPR_DECL, DEBUG_EXPRs
will be still reused in between functions otherwise and within the same
function the mode should be always the same.

preprocessor: Fix cpp_avoid_paste for digit separators
The libcpp function cpp_avoid_paste is used to insert whitespace in
preprocessed output where needed to avoid two consecutive
preprocessing tokens, that logically (e.g. when stringized) do not
have whitespace between them, from being incorrectly lexed as one when
the preprocessed input is reread by a compiler.
This fails to allow for digit separators, so meaning that invalid
code, that has a CPP_NUMBER (from a macro expansion) followed by a
character literal, can result in preprocessed output with a valid use
of digit separators, so that required syntax errors do not occur when
compiling with -save-temps. Fix this by handling that case in
cpp_avoid_paste (as with other cases in cpp_avoid_paste, this doesn't
try to check whether the language version in use supports digit
separators; it's always OK to have unnecessary whitespace in
preprocessed output).
Note: there are other cases, with various kinds of wide character or
string literal following a CPP_NUMBER, where spurious pasting of
preprocessing tokens can occur but the sequence of tokens remains
invalid both before and after that pasting. Maybe cpp_avoid_paste
should also handle those cases (and similar cases after a CPP_NAME),
to ensure the sequence of preprocessing tokens in preprocessed output
is exactly right, whether or not it affects whether syntax errors
occur. This patch only addresses the case with digit separators where
invalid code can fail to be diagnosed without the space inserted.

divided into two based on whether the indexed operand had the same mode

divide them instead based on whether the indexed operand was 64-bit or
128-bit, since that maps directly to the arm_neon.h “q” conventions.

openmp: Fix up taskloop reduction ICE if taskloop has no iterations [PR100471]
When a taskloop doesn't have any iterations, GOMP_taskloop* takes an early
return, doesn't create any tasks and more importantly, doesn't create
a taskgroup and doesn't register task reductions. But, the code emitted
in the callers assumes task reductions have been registered and performs
the reduction handling and task reduction unregistration. The pointer
to the task reduction private variables is reused, on input it is the alignment
and only on output it is the pointer, so in the case taskloop with no iterations
the caller attempts to dereference the alignment value as if it was a pointer
and crashes. We could in the early returns register the task reductions
only to have them looped over and unregistered in the caller, but I think
it is better to tell the caller there is nothing to task reduce and bypass
all that.

Note that this doesn't fix the testcases in PR83035 or PR99692 because
there the dependent operator expressions aren't at function scope. I'm

c++: fn parm pack expansion inside constraint [PR100138]
This PR is about CTAD but the underlying problems are more general;
CTAD is a good trigger for them because of the necessary substitution
into constraints that deduction guide generation entails.
In the testcase below, when generating the implicit deduction guide for
the constrained constructor template for A, we substitute the generic
flattening map 'tsubst_args' into the constructor's constraints. During
this substitution, tsubst_pack_expansion returns a rebuilt pack
expansion for sizeof...(xs), but doesn't carry over the
PACK_EXPANSION_LOCAL_P (and PACK_EXPANSION_SIZEOF_P) flag from the
original tree to the rebuilt one. The flag is otherwise unset on the
original tree but gets set for the rebuilt tree from make_pack_expansion
since at_function_scope_p() is true (we're inside main). This leads to
a crash during satisfaction when substituting into the pack expansion
because we don't have local_specializations set up (and it'd be set up
for us if PACK_EXPANSION_LOCAL_P is unset)
Similarly, tsubst_constraint needs to set cp_unevaluated so that the
substitution performed therein doesn't rely on local_specializations.
This avoids a crash during CTAD for C below.

ipa: Get rid of IPA_NODE_REF and IPA_EDGE_REF
The node and edge summaries defined in ipa-prop.h are probably the
oldest in GCC and so it happened that they are the only ones using
macros to look them up and create them. With Honza and Martin we
agreed it is ugly and the macros should be removed and the ipa-prop
summaries should be accessed like all the other ones but somehow I
never got to it until now.
The patch is mostly mechanical. Because the lookup machinery was much
simpler in the old times (something like the fast summaries we have
today), a lot of code queried for the summary multiple times for no
good reasons and I fixed that in places where it was easy.
Also, before we switched to hash based summaries, new summary pointers
had to be obtained whenever the underlying array could be reallocated
because of new cgraph nodes/edges. This is no longer necessary and so
I removed the instances which I found.
Both kinds of these non-mechanical changes should be specifically called
out in the ChangeLog.
I also removed the IS_VALID_JUMP_FUNC_INDEX macro because it not used
anywhere.

libstdc++: Rename test type to avoid clashing with std::any
When PCH are enabled this test file includes <any> and so the
using-directive brings std::any into the global scope. It isn't
currently a problem, because the -std option in the dg-options means
that PCH is not used. If that option is removed, the test fails with PCH
and passes without.
This just renames the type to avoid the name classh (and also the 'none'
type for consistency).

arm: MVE: Factorize all vcmp* integer patterns
After removing the signed and unsigned suffixes in the previous
patches, we can now factorize the vcmp* patterns: there is no longer
an asymmetry where operators do not have the same set of signed and
unsigned variants.
The will make maintenance easier.
MVE has a different set of vector comparison operators than Neon,
so we have to introduce dedicated iterators.
