expr: Fix fallout from optimize store_expr from STRING_CST [PR95052]
> Can't hurt, and debugging the assert tripping is likely a hell of a lot easier

> for it.
Testing passed, so I've committed it with those asserts (and thankfully I've
added them!) but it apparently broke Linux kernel build on arm.
The problem is that if the STRING_CST is very short, while the full object
has BLKmode, the short string could very well have
QImode/HImode/SImode/DImode and in that case it wouldn't take the path that
copies the string and then clears the remaining space, but different paths
in which it will ICE because of those asserts and without those it would
just emit wrong-code.
The following patch fixes it by enforcing BLKmode for the string MEM, even
if it is short, so that we copy it and memset the rest.

Simplify tree streaming.
this patch cleans up tree streaming. The code is prepared to stream nested
trees, but we only handle flat trees. As a result we have quite heavy function
to stream in/out tree reference which is used many times and shows up in
profile.
This patch adds stream_write_tree_ref/stream_read_tree_ref which is used to
stream references to trees that are required to exist in the cache or be
indexable.
The actual implementation is just a first cut. I would like to make it more
compact. We used to stream 2 byte tag (as UHWI) + UHWI representing the index.
Now we stream one UHWI that represent type of reference + index for references
to cache, but still two integers for references to global stream. This is
becaue the abstraction is not very helpful here and I want to clean this up
incrementally.
I would also like to get rid of the ref_p parameters which seems unnecessary for
flat streams.
This reduces around 7% of global stream, 3% when compressed.
More reduction will happen once the format is sanitized a bit.

c++: lambdas inside constraints [PR92652]
When parsing a constraint-expression, a requires-clause or a
requires-expression, we temporarily increment processing_template_decl
so that we always obtain template trees which we could later reduce via
substitution even when not inside a template.
But incrementing processing_template_decl when we're already inside a
template has the unintended side effect of shifting up the template
parameter levels of a lambda defined inside one of these constructs,
which leads to confusion later during substitution into the lambda.
This patch fixes this issue by incrementing processing_template_decl
during parsing of these constructs only if it is 0.
Passes 'make check-c++', and also tested by building cmcstl2, does this

index:
{{aggr_init_expr<...>, [1...2]={.off=1}}}
but get_or_insert_ctor_field isn't prepared to handle looking up a
RANGE_EXPR index.
This patch adds limited support to get_or_insert_ctor_field for looking
up a RANGE_EXPR index. The limited scope of this patch should make it
more suitable for backporting, and more extensive support would be
needed only to handle self-modifying CONSTRUCTORs that contain a
RANGE_EXPR index, but I haven't yet been able to come up with a testcase
that actually creates such a CONSTRUCTOR.

tree-optimization/95272 - add SLP_TREE_REPRESENTATIVE
This adds SLP_TREE_REPRESENTATIVE - a representative stmt-info that
is used by SLP analysis and code generation. This avoids the need
for the hack in vect_slp_rearrange_stmts which previously avoided
to re-arrange stmts that might not have been isomorphic because
of operand swapping. It also plays nice with future directions of SLP
and for the forseeable future is easier than replicating more and

allocation or not).
However, aarch64_layout_frame was leaving these fields with

aarch64: Fix segfault in aarch64_expand_epilogue [PR95361]
The stack frame for the function in the testcase consisted of two
SVE save slots. Both saves had been shrink-wrapped, but for different
blocks, meaning that the stack allocation and deallocation were
separate from the saves themselves. Before emitting the deallocation,
we tried to attach a REG_CFA_DEF_CFA note to the preceding instruction,
to redefine the CFA in terms of the stack pointer. But in this case
there was no preceding instruction.
This in practice only happens for SVE because:
(a) We don't try to shrink-wrap wb_candidate* registers even when
we've decided to treat them as normal saves and restores.
I have a fix for that.
(b) Even with (a) fixed, we're (almost?) guaranteed to emit
a stack tie for frames that are 64k or larger, so we end
up hanging the REG_CFA_DEF_CFA note on that instead.
We should only need to redefine the CFA if it was previously
defined in terms of the frame pointer. In other cases the CFA
should already be defined in terms of the stack pointer,
so redefining it is unnecessary but usually harmless.

gcc-changelog: enhance handling of renamings
So far, we expect from a commit that renames a file to contain a
changelog entry only for the new name. For example, after the following
commit:
$ git move foo bar
$ git commit
We expect the following changelog:
* bar: Renamed from foo.
Git does not keep track of renamings, only file deletions and additions.
The display of patches then uses heuristics (with config-dependent
parameters) to try to match deleted and added files in the same commit.
It is thus brittle to rely on this information.
This commit modifies changelog processing so that renames are considered
as a deletion of a file plus an addition of another file. The following
changelog is now expected for the above example:
* foo: Move...
* bar: Here.

outputs.exp: no lto, linker default output, cdtor temps, empty args
This patch fixes various issues in the testsuite that came up after
the dump/aux output revamp, namely:
- many outputs.exp tests used -flto without checking that LTO was
supported, getting lots of failures. With this patch, we test for LTO
support, and skip -flto tests on platforms that do not support it.
- some linkers error out if an output file is not named, and the
a.{out,exe} construct that we used throughout outputs.exp to match the
default linker output would trigger a bug in tcl globbing. With this
patch, we detect the default linker output early. If none is found,
we arrange to pass -o a.out explicitly in tests that used to test the
default linker output. We now look for the detected default, or for
explicitly-specified output.
- collect2 will leave <execname>.cdtor.* files behind in -save-temps
tests. Ignore them.
- The prepending of -Wl, to file names in ldflags et al was done in a
way that introduced empty arguments when consecutive blanks appeared
in these board configuration knobs. Skip the empty strings between
consecutive blanks to avoid this problem.

libstdc++: Fix view adaptors for mixed-const sentinels and iterators (PR 95322)
The bug report is that transform_view's sentinel<false> cannot be
compared to its iterator<true>. The comparison is supposed to use
operator==(iterator<Const>, sentinel<Const>) after converting
sentinel<false> to sentinel<true>. However, the operator== is a hidden
friend so is not a candidate when comparing iterator<true> with
sentinel<false>. The required conversion would only happen if we'd found
the operator, but we can't find the operator until after the conversion
happens.
A new LWG issue has been reported, but not yet assigned a number. The
solution suggested by Casey Carter is to make the hidden friends of the
sentinel types work with iterators of any const-ness, so that no
conversions are required.
Patrick Palka observed that join_view has a similar problem and a
similar fix is used for its sentinel.

libstdc++: Fix std::reverse_iterator comparisons (PR 94354)
The std::reverse_iterator comparisons have always been implemented only
in terms of equality and less than. In C++98 that made no difference for
reasonable code, because when the underlying operators are the same type
they are required to support all comparisons anyway.
But since LWG 280 it's possible to compare reverse_iterator<X> and
reverse_iterator<Y>, and comparisons between X and Y might not support
the full set of equality and relational operators. This means that it
matters whether we implement operator!= as x.base() != y.base() or
!(x.base() == y.base()), and the current implementation is
non-conforming.

for all other -std modes.

Add debug (slp_tree) and dump infrastructure for this
This adds an alternate debug_dump_context similar to the one for
selftests but for interactive debugging routines. This allows
to share code between user-visible dumping via the dump_* API
and those debugging routines. The primary driver was SLP node
dumping which wasn't accessible from inside a gdb session up to
now.

openmp: Fix up omp_declare_variant{s,_alt} htab handling
This patch fixes a GC ICE. During debugging, I've found that during
gimplification we can actually call omp_resolve_declare_variant multiple
times and it would create a new magic declare_variant_alt FUNCTION_DECL
each time, which is undesirable, once we have such a decl, we should just
use that. The other problem is that there was no cgraph node removal hook.
As the omp_declare_variants htab is used just early during gimplification,
we can just clear the whole htab, rather than trying to lookup and remove
a particular entry. The other hash table is used later as well and that
one uses just DECL_UID as hash, so in that case the patch removes the elt.

Rewrite maintainer-scripts/update_version_git
This patch rewrites update_version_git to be just a thin wrapper around
Martin's new python script. This just arranges to check out the gcc
repo in a temporary directory, copy out the contrib scripts so that
the running script doesn't change with branch checkouts and runs the script.
I've run it today manually but hopefully we can do it from cron again
from tomorrow.
