These scripts both print "generated by $file, do not edit" header but
one of them prints the wrong filename. Use the built-in __file__

I'm seeing errors for --enable-maintainer-mode builds due to incorrectly

'python' on some systems (e.g. SLES 15) might be Python 2. Prefer python3,

libcc1 is not listed as bug component even though it is there in bugzilla.
This fixes that oversight.

Committed as obvious after testing using git gcc-verify on a patch.

	* gcc-changelog/git_commit.py (bug_components): Add libcc1.

The following deprecates ia64*-*-* for GCC 14.  Since we plan to
force LRA for GCC 15 and the target only has slim chances of getting
updated this notifies people in advance.  Given both Linux and
glibc have axed the target further development is also made difficult.
There is no listed maintainer for ia64 either.

	PR target/90785
gcc/
	* config.gcc: Add ia64*-*-* to the list of obsoleted targets.

contrib/
	* config-list.mk (LIST): --enable-obsolete for ia64*-*-*.

gcc/Makefile.in since my r0-60234 change fills in HOSTCC and HOSTCFLAGS
in site.exp and since r8-671 also HOSTCXX and HOSTCXXFLAGS.
If those variables aren't set, we get errors like:

(similarly in g++ or gfortran) struct-layout-1.exp.  One doesn't need to
test specially for just struct-layout-1.exp alone, just not using any arg
will trigger it as well, just later.

The following patch fills it in as cc and c++ with empty flags to compile
those, I believe that is what e.g. make uses by default, so it should be a
reasonable default.  We IMHO shouldn't default to GCC_UNDER_TEST because
that might be a cross-compiler etc.

DejaGNU changed its header line from "Test Run By" to "Test run by"
around 2016.  This patch makes it so that both alternatives are
correcly detected.

contrib/ChangeLog:

	* dg-extract-results.py: Make the test_run regex case
	insensitive.

Fix some copy & pasted logic in __is_extended_pictographic. This
function should yield false for the values before the first edge, not
true. Also add a missing boundary condition check in __incb_property.

Also Fix an off-by-one error in _Utf_iterator::operator++() that would
make dereferencing a past-the-end iterator undefined (where the intended
design is that the iterator is always incrementable and dereferenceable,
for better memory safety).

Also simplify the grapheme view iterator, which still contained some
remnants of an earlier design I was experimenting with.

Slightly tweak the gen_libstdcxx_unicode_data.py script so that the
_Gcb_property enumerators are in the order we encounter them in the data
file, instead of sorting them alphabetically. Start with the "Other"
property at value 0, because that's the default property for anything
not in the file. This makes no practical difference, but seems cleaner.
It causes the values in the __gcb_edges table to change, so can only be
done now before anybody is using this code yet. The enumerator values
and table entries become ABI artefacts for the function using them.

contrib/ChangeLog:

	* unicode/gen_libstdcxx_unicode_data.py: Print out Gcb_property
	enumerators in the order they're seen, not alphabetical order.

	member and find end of cluster lazily.

This implements the requirements in the following proposals, which
dictate how std::format deals with non-ASCII strings:
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1868r1.html
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p2572r1.html
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p2675r1.pdf

There are two parts to this. The width estimation for strings must only
count the width of the first character in an extended grapheme cluster.
That requires implementing the algorithm for detecting cluster breaks,
which requires a number of lookup tables of the grapheme cluster break
properties (and Indic_Conjunct_Break and Extended_Pictographic
properties) of every code point. Additionally, some characters have a
field width of 2, which requires another lookup table of field widths
for every code point.  The tables added in this commit do not contain
entries for every code point from 0 to 0x10FFFF as that would be very
inefficient and use too much memory. Instead the tables only contain the
code points that form an "edge" for a property, omitting all the code
points that have the same property as the preceding one. We can use a
binary search to find the closest code point in the table that is not
greater than the one we're looking for.

The tables are generated by a new Python script added to the
contrib/unicode directory, and a new data file downloaded from the
Unicode Consortium website.

The rules for extended grapheme cluster breaking are implemented for the
latest Unicode standard, version 15.1.0.

update-copyright.py --this-year FAILs on two spots in the modula2
directories.
One is gpl_v3_without_node.texi, I think that is similar to other
license files which we already exclude from updates.
And the other is GmcOptions.cc, which has lines like
  mcPrintf_printf0 ((const char *) "Copyright ", 10);
  mcPrintf_printf1 ((const char *) "Copyright (C) %d Free Software Foundation, Inc.\\n", 49, (const unsigned char *) &year, (sizeof (year)-1));
  mcPrintf_printf1 ((const char *) "Copyright (C) %d Free Software Foundation, Inc.\\n", 49, (const unsigned char *) &year, (sizeof (year)-1));
which update-copyhright.py obviously can't grok.  The file is generated
and doesn't contain normal Copyright year which should be updated, so I think
it is also ok to skip it.

2024-01-03  Jakub Jelinek  <jakub@redhat.com>

	* update-copyright.py (GenericFilter): Skip gpl_v3_without_node.texi.
	(GCCFilter): Skip GmcOptions.cc.

When compare_tests compares both C and C++ tests in c-c++-common, they
get the same identifier, so expected differences in results across
languages become undesirably noisy.

This patch adds tool identifiers to tests, so that runs by different
tools are not confused by the compare logic.

It also fixes a bug in reporting differences, that would attempt to
print an undefined fname (the definitions are in subshell loops), and
adjusts the target insertion to match tabs in addition to blanks after
colons.

	* compare_tests: Add tool to test lines.  Match tabs besides
	blanks to insert tool and target.  Don't print undefined fname.
