Removing private class members, code unused by ETL in "private"
namespaces, code unreachable via preprocessor guards (C++11 inside
C++03).
For code still to be kept, even though unused at first sight, add
tests.
Correct move behavior of `TestDataM` - it should preserve `valid` value.
Implemented overloads of `etl::make_optional` free function.
Extend optional moveable tests
- fundamental vs non-fundamental
- move construct/assign from valueless
- Verify nothrow of `etl::swap` for `etl::optional`.
Ubuntu 26.04 is not available in github workflows directly and won't be soon.
But ubuntu-26.04 is available as docker container. So use it for running
C++26 workflows which were disabled previously.

* Print test names at test time (#1343)
* Fix operator| conflict with std::ranges (#1395)
* Fix missing tuple_size
In case of certain clang versions, a wrong combination of activated
and deactivated template forward declarations and specializations
were provided.
This led to redefinition errors and specialization errors.
Now aligning those combinations, and providing definitions from
<utility> from std in the STL using case.

* Move operators for etl::unique_ptr to etl namespace
This is in accordance with the operators of std::unique_ptr. Also,
it doesn't pollute the global namespace, and also works together
with ADL, finding the operators in the etl namespace now.

* Fix delegate not being cleared by assigning empty braces
Fixes issue #1399.
The non-capturing lambda support (PR#1295) added a non-explicit
delegate(function_ptr) constructor and operator=(function_ptr). This
caused `delegate = {}` to implicitly convert `{}` to a null function
pointer and bind it via function_ptr_stub, leaving the delegate
appearing valid (stub != nullptr) but invoking through a null pointer
(undefined behavior).
Fix:
- Mark delegate(function_ptr) constructor explicit to prevent implicit
conversion from `{}` during initialization.
- In operator=(function_ptr), clear the delegate when fp is null
instead of binding a null pointer through function_ptr_stub.
Added tests verifying that both `delegate d = {}` and `d = {}` produce
an invalid (cleared) delegate.
* Fix Dockerfile for powerpc cross build

Includes C++26 related infrastructure macros.
Fixes compile errors when compiling under C++26.
Initially supported C++26 features:
- [[indeterminate]]
- new 2022 ISO prefixes in ratio.h
- atomic fetch_max() and fetch_min()
- is_virtual_base_of
- is_trivially_relocatable and trivially_relocate
- saturation arithmetic: add_sat, sub_sat, mul_sat, div_sat, saturate_cast
* Extensions for testing
Generalize run-tests.sh
Test all C++ versions at once
Fix combination of big endian and -Wsign-conversion
Failed on s390x (as reference for big endian)
Add github workflow for s390x
Add armhf container files
Devcontainers for i386 and riscv
Add github workflows for armhf, i386 and riscv64
Add run-tests.sh for foreign architectures
Document testing in doc/testing.md
Adjustments from clang-format run
Fix .devcontainer/s390x/Dockerfile for linebreak syntax
Fix exit code of run-test.sh
Previously, "exit $?" was used, actually the return value of
FailedCompilation and FailedTest which are always 0.
Now just using 1.
In run-tests.sh at ctest, use -V for printing number of tests unconditionally
While ctest suppresses individual test list by default, it didn't even
print the number of tests anymore, as run_tests.sh does because
it suppresses it output completely.
Now, by default print number of tests, and in verbose mode, print test list
in addition.
* Support powerpc as foreign architecture
* Add SFINAE constraints to etl::begin/end and reverse iterator free functions
The unconstrained etl::begin(), etl::end(), etl::cbegin(), etl::cend(),
etl::rbegin(), etl::rend(), etl::crbegin(), and etl::crend() templates
in the no-STL code path were matching iterator types during ADL, causing
a hard error with GCC 15's std::ranges::begin. When std::ranges performed
ADL on an etl::*::iterator, it found etl::begin() as a candidate; since
the iterator type has a nested iterator typedef, the return type TContainer::iterator
was valid, but calling .begin() on the iterator failed.
Fix: add etl::void_t<decltype(...)> SFINAE guards to each template,
ensuring they only participate in overload resolution when TContainer
actually has the corresponding member function (.begin(), .end(), etc.).
* - Fix red unit tests on 32 bits big-endian platform.
* Document powerpc architecture for testing
* Use Dockerfiles in cross testing github workflows
Synchronizes environment setup for github workflows to what is
defined in the development Dockerfiles. So they don't need to
be maintained separately.

* Print test names at test time (#1343)
* Fix chrono.h year_month_weekday_last and year_month_weekday sysdays()
Bug 1: year_month_weekday_last::operator sys_days() — wrong weekday construction
The code was constructing a weekday from a raw day count using weekday(unsigned),
which treats the value as a weekday encoding (0–6). The fix uses weekday(sys_days),
which correctly accounts for the epoch being a Thursday (+4 offset).
Bug 2: year_month_weekday::operator sys_days() — same wrong weekday
construction + off-by-one in day_of_month
Same weekday(unsigned) vs weekday(sys_days) issue. Additionally, the day_of_month
calculation was missing the 1 + base — it computed a 0-based offset from day 1,
but forgot to add the 1 back when converting to an actual day number.

Previously, generator code under include/etl/generators needed to be
synchronized with the generated files under include/etl explicitly.
Leading to errors in the CI checks if forgotten.
This change separates out the generated parts to cpp03 specific
snippets. This way, most code under include/etl is now directly editable,
with only some pre-C++11 code separated out to
include/etl/generators/*_cpp03_generator.h which still needs to be
re-generated on respective changes. But in many cases, this is not necessary.
