Run C++26 workflows with docker (#1421)
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.

Fix delegate not being cleared by assigning empty braces (#1401)
* 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

Debian snapshot sources were mixed with plain sid sources which
mismatched after a while. Now, aligning all sources from snapshot
server.

Extensions for testing (#1380)
* 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.

* Suppress false positive compiler warnings when compiling with -O3

The CI checks currently only check everything with -O0. Wenn activating
higher optimization levels, more warnings kick in. Leading to errors,

Fix chrono.h year_month_weekday_last and year_month_weekday sysdays() (#1396)
* 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.

span is constructible from temporary (#1338)
* Added missing files from VS2022 project

* Added global data() overloads to complement etl::size()

* Added C++03 compatible implementation of etl::is_convertible

* Updated etl::span to more closely align with std::span

* Fix etl::rotate (#1327)

Per the C++ standard, std::rotate returns first + (last - middle):

* When first == middle, return last
* When middle == last, return first

* Fix greater_equal and less_equal (#1331)

* Align comparison operators (#1330)

In functional.h, the comparison operators for equal_to and not_equal_to
mismatch between the actual comparison execution and the type inference
for the return type. This change adjusts it by using the same operator==()
in the return type inference as used in the comparison execution.

When ETL_FORMAT_NO_FLOATING_POINT is defined, all floating-point formatting support (float, double, long double) is excluded from etl::format. This reduces code size on targets that do not require floating-point formatting.

Guarded sections:

- #include <cmath>

- float/double/long double in supported_format_types variant

- float/double/long double constructors in basic_format_arg

- format_floating_* functions and format_aligned_floating

- formatter<float>, formatter<double>, formatter<long double>

- Floating-point test cases in test_format.cpp

Enforce o(log n) dispatch for messages when using fsm for c++11 and up (#1337)
* Updated message handling to be worst case O(logN)

* Copied optimised message handling from etl::fsm

* Updated fsm generator

* Updated message_router generator

* Added optimised accepts() member function

* Modified comment, as the FSM doesn't support a successor

* Updated version and release notes

* Hotfix/etl  multiset iterator invalidation during erase leads to incorrect sorted order in depth first traversal (#1317)

* Fixed issue for both multiset and multimap

* Added std::is_sorted checks to all map/set tests

* Updated with coderabbit suggestions

* Updated release notes and version

* Changed std::is_same to etl::is_same in struct type_list_is_unique (#1320)

Co-authored-by: John Wellbelove <john.wellbelove@etlcpp.com>

* Updated release notes and version

* Fix etl::rotate (#1327)

Per the C++ standard, std::rotate returns first + (last - middle):

* When first == middle, return last
* When middle == last, return first

* Added missing files from VS2022 project

* Fix greater_equal and less_equal (#1331)

* Align comparison operators (#1330)

In functional.h, the comparison operators for equal_to and not_equal_to
mismatch between the actual comparison execution and the type inference
for the return type. This change adjusts it by using the same operator==()
in the return type inference as used in the comparison execution.

* Add ETL_FORMAT_NO_FLOATING_POINT control macro for etl::format (#1329)

When ETL_FORMAT_NO_FLOATING_POINT is defined, all floating-point formatting support (float, double, long double) is excluded from etl::format. This reduces code size on targets that do not require floating-point formatting.

Guarded sections:

- #include <cmath>

- float/double/long double in supported_format_types variant

- float/double/long double constructors in basic_format_arg

- format_floating_* functions and format_aligned_floating

- formatter<float>, formatter<double>, formatter<long double>

- Floating-point test cases in test_format.cpp

* Changes from review of algorithm.h on development branch (#1340)

* Add missing constexpr in algorithm.h

* Fix call of nth_element

2nd argument (nth) was missing

* Replace partition point with O(log(N)) algorithm

The C++ standard defines O(log(N)) calls of predicate as the

In case of predicate not equal_to, the calculation previously
returned wron results

* Omit swap in selection_sort if iterators are equal

* Use difference_type in rotate_general() instead of int

* Typo fix in algorithm.h

Fix undefined behaviour of etl::absolute() for etl::numeric_limits<T>::min (#1333)
absolute_unsigned() already handled that case correctly. Now adding this
check to absolute() also. It can be caught at compile time now, if in a
constexpr context. Also separating integral and non-integral versions
via enable_if.
