Make ipriority_queue non-sized base class (#1459)
* Fix iterator access algorithm.h

Move from operator[] access to operator+ and operator- to prevent
limited compatibility. This worked before for vector because of
iterators being ptrdiff_t (signed), but not for unsigned access
like size_t as in etl::queue.

* Make ipriority_queue non-sized base class

Fixes issue #1457

Make Constructors of Atomics for trivial Types constexpr (#1453)
* Bold project documentation link in README

* Add constexpr to trivial Atomics

According to https://en.cppreference.com/cpp/atomic/atomic/atomic the constructors of atomics should be constexpr. This change marks (at least for the trivial types) the constructor as constexpr.

Add more constexpr to constructors (#1450)
* Add more constexpr to ctors

* Adjust operator!=() in fixed_iterator.h

Instead of taking an iterator by reference, take it by value as
done in the other operators and overloads.

* Initialize move_iterator() current member

Prevent indeterminate values

* Fix fixed_iterator::operator* return type

fixed_iterator::operator* returned value_type by value, so writes like *it = ...
modified a temporary rather than the underlying location. This broke the
iterator’s intended use (e.g., writing to a fixed register/memory location).
Now returning iterator_traits<TIterator>::reference instead (const and
non-const overloads).

* Fixed move_iterator::operator+= and operator-= return type

move_iterator::operator+= / operator-= returned by value, but RandomAccessIterator
requirements (and std::move_iterator) expect these to return move_iterator&.
Returning by value also added an unnecessary copy and could break generic code
expecting reference semantics.

Fix format: float zero-padding, nested replacement width, octal alternate form, and extreme doubles (#1442)
format.h:
- Fix float zero-padding ({:010f}): output sign first, then zero-fill,
  then the unsigned formatted value, matching std::format behavior.
- Fix nested replacement fields ({:{}d}): consume the value's auto-index
  in parse_format_spec before parsing nested width/precision fields, so
  auto-indexing order matches the C++ standard.
- Fix {:#o} with value 0: produce "0" instead of "00" by skipping the
  octal prefix when the value is zero.
- Fix format_floating_default overflow for extreme doubles (DBL_MIN,
  DBL_MAX): fall back to scientific notation for values >= 1e18 or
  tiny positives < 1e-6, delegating to format_floating_e.
- Fix format_floating_e precision loss: replace iterative multiply-by-10
  normalization loop with O(1) log10/pow/floor computation.
- Add resolve_nested_replacements helper to extract width/precision
  from format args at formatting time.

test_format.cpp:
- Add tests for float zero-padding, nested replacement width, octal
  alternate form with zero, float sign/width/alignment, negative floats,
  scientific notation for large/small values, default-to-scientific
  switch, positive zero, brace escaping, and integer limits.

format.h + platform.h:
- log10l fix for different toolchain support:
  Define ETL_FORMAT_NO_LONG_DOUBLE_MATH in the profile if libm doesn't
  provide log10l. This is identified by linker error missing this symbol.
  It was identified with the llvm/clang cross toolchain for ARM.

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.

Generalize run-tests.sh

Fix combination of big endian and -Wsign-conversion

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.

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.

* Restrict etl::atomic for general types

Needs adding is_copy_assignable and is_move_assignable, and
adjustments to is_trivially_copyable and is_assignable

They are deprecated in C++20 because they don't work as users expect anyway.

MSVC hinted for this.

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.

* 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

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.

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
