	* update_web_docs_git (CSS): Update CSS reference to point to
	/texinfo-manuals.css.

The @gol macro appears to have existed as a workaround for a bug in old
versions of makeinfo and/or texinfo.tex, where they would, in some types
of output, fail to emit line breaks in @gccoptlists.  After updating
texinfo.tex, I noticed that this behavior appears to no longer be
exhibited, instead, both acted correctly and inserted newlines.  The
(groff) manual output also appears unaffected.

gcc/ChangeLog:

	* doc/implement-c.texi: Remove usage of @gol.
	* doc/invoke.texi: Ditto.
	* doc/sourcebuild.texi: Ditto.
	* doc/include/gcc-common.texi: Remove @gol.  In new Makeinfo and
	texinfo.tex versions, the bug it was working around appears to
	be gone.

	* invoke.texi: Remove usages of @gol.
	* intrinsic.texi: Ditto.

gcc/ChangeLog:

	* doc/include/texinfo.tex: Update to 2023-01-17.19.

The @defbuiltin{,x} macros are convenience macros for the often-repeated
task of defining a built-in function in extend.texi.  Usage of this
macro should lead to a higher degree of consistency across pieces of
text written by different people, and provide a better reading
experience, as they prevent easy-to-make errors, like forgetting index
entries for these functions.

gcc/ChangeLog:

	* doc/include/gcc-common.texi: Add @defbuiltin{,x} and
	@enddefbuiltin for defining built-in functions.
	* doc/extend.texi: Apply @defbuiltin{,x} to many, but not all,
	places where it should be used.

This commit addresses a few minor errors that were spotted while testing
the GCC manual with a few people, and while working on wider changes.

gcc/ChangeLog:

	* doc/extend.texi (Formatted Output Function Checking): New
	subsection for  grouping together printf et al.
	(Exception handling) Fix missing @ sign before copyright
	header, which lead to the copyright line leaking into
	'(gcc)Exception handling'.
	* doc/gcc.texi: Set document language to en_US.
	(@copying): Wrap front cover texts in quotations, move in manual
	description text.

The GCC manual has multiple indices.  By creating an appendix which
lists them, we help makeinfo present a more accessible way for the
reader to see all the indices.

gcc/ChangeLog:

	* doc/gcc.texi: Add the Indices appendix, to make texinfo
	generate nice indices overview page.

The following adds a missing range-op for __builtin_expect which
helps -Wuse-after-free to detect the case a realloc original
pointer is used when the result was NULL.  The implementation
should handle all argument one pass-through builtins we handle
in the fnspec machinery, but that's defered to GCC 14.

The gcc.dg/tree-ssa/ssa-lim-21.c testcase needs adjustment because

   for (int j = 0; j < m; j++)
     if (__builtin_expect (m, 0))
       for (int i = 0; i < m; i++)

is now correctly optimized to a unconditional jump by EVRP - m
cannot be zero when the outer loop is entered.  I've adjusted
the outer loop to iterate 'n' times which makes us apply store-motion
to 'count' and 'q->data1' but only out of the inner loop and
as expected not apply store motion to 'q->data' at all.

The gcc.dg/predict-20.c testcase relies on broken behavior of
profile estimation when trying to handle __builtin_expect values
flowing into PHI nodes.  I have opened PR109210 and removed
the expected matching from the testcase.

When I implemented explicit(bool) in r9-3735, I added this code to
add_template_candidate_real:
+  /* Now the explicit specifier might have been deduced; check if this
+     declaration is explicit.  If it is and we're ignoring non-converting
+     constructors, don't add this function to the set of candidates.  */
+  if ((flags & LOOKUP_ONLYCONVERTING) && DECL_NONCONVERTING_P (fn))

but as this test demonstrates, that's incorrect when we're initializing
from a {}: for list-initialization we consider explicit constructors and
complain if one is chosen.

The following two testcases are miscompiled, because we keep TREE_READONLY
on the vars even when they are (possibly) dynamically initialized by a TLS
wrapper function.  Normally cp_finish_decl drops TREE_READONLY from vars
which need dynamic initialization, but for TLS we do this kind of
initialization upon every access to those variables.  Keeping them
TREE_READONLY means e.g. PRE can hoist loads from those before loops
which contain the TLS wrapper calls, so we can access the TLS variables
before they are initialized.

This patch reworks how the complex multiply and divide built-in functions are
done.  Previously GCC created built-in declarations for doing long double complex
multiply and divide when long double is IEEE 128-bit.  However, it did not
support __ibm128 complex multiply and divide if long double is IEEE 128-bit.

This code does not create the built-in declaration with the changed name.
Instead, it uses the TARGET_MANGLE_DECL_ASSEMBLER_NAME hook to change the name
before it is written out to the assembler file like it now does for all of the
other long double built-in functions.

I've noticed this testcase FAILs on i686-linux with
-fstack-protector-strong.

sizeof (auto_vec<int, 8>) == 16, which in this case contains
4-byte m_vec (which points to to m_auto), then 8-byte m_auto
which contains just 8-byte m_vecpfx and finally 1 byte m_data,
rest is padding.  We then try to push 2 ints to it, so 8 bytes,
starting at the end of m_vecpfx aka address of m_data, but there
is just 1 byte + 3 bytes of padding.
In the lp64 case, I think sizeof (auto_vec<int, 8>) == 24,
because there is 8-byte m_vec, 8-byte m_vecpfx and 1-byte m_char
all with 8-byte alignment.

PR analyzer/109094 reports an ICE in the analyzer seen on qemu's
target/i386/tcg/translate.c

The issue turned out to be that when handling a longjmp, the code
to pop the frames was generating an svalue for the result_decl of any
popped frame that had a non-void return type (and discarding it) leading
to "uninit" poisoned_svalue_diagnostic instances being saved since the
result_decl is only set by the greturn stmt.  Later, when checking the
feasibility of the path to these diagnostics, m_check_expr was evaluated
in the context of the frame of the longjmp, leading to an attempt to
evaluate the result_decl of each intervening frames whilst in the
context of the topmost frame, leading to an assertion failure in
frame_region::get_region_for_local here:

919		case RESULT_DECL:
920		  gcc_assert (DECL_CONTEXT (expr) == m_fun->decl);
921		  break;

This patch updates the analyzer's longjmp implementation so that it
doesn't attempt to generate svalues for the result_decls when popping
frames, fixing the assertion failure (and presumably fixing "uninit"
false positives in a release build).

We ICE in combine_reload_insn if we've deleted the TO insn operand during
processing, because lra_get_insn_recog_data doesn't expect to see the note
that replaces the deleted insn.  The solution here is to exit early if TO
is a debug insn or note.

	PR rtl-optimization/109179
	* lra-constraints.cc (combine_reload_insn): Enforce TO is not a debug
	insn or note.  Move the tests earlier to guard lra_get_insn_recog_data.

Avoid unweildy structure-layout-specific message-matching
expressions by exluding targets that lay out structures as
if they had been specified with __attribute__ ((__packed__)),
for tests where multiple messages depend on the structure
layout.

It's arguably a judgement call whether to skip some of these
tests or add multiple lines of matches depending on the
layout of structures.

When a lambda refers to a constant local variable in the enclosing scope, we
tentatively capture it, but if we end up pulling out its constant value, we
go back at the end of the lambda and prune any unneeded captures.  Here
while parsing the template we decided that the dim capture was unneeded,
because we folded it away, but then we brought back the use in the template
trees that try to preserve the source representation with added type info.
So then when we tried to instantiate that use, we couldn't find what it was
trying to use, and crashed.

Fixed by not trying to prune when parsing a template; we'll prune at
instantiation time.

do_friend was only considering class-qualified identifiers for the
qualified-id case, but we also need to skip local scope when there's an
