* 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.

* Fix copy and move in signal.h
* Delete copy and move in callback_service.h
The implicitly provided copy and move copied internal pointers
which are invalid after copying.
* Delete copy and move in delegate_service.h
The implicitly provided copy and move copied internal pointers
which are invalid after copying.
* 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.
* Print test names at test time (#1343)
* Fix operator| conflict with std::ranges (#1395)
* Added etl::intrusive_avl_tree class.
* PR review minor fixes.
* Fix `std::move` -> `etl::move`
* Apply AI spell checking
* Try to fix C++03 build.

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.
* Print test names at test time (#1343)
* Fix operator| conflict with std::ranges (#1395)
* Add test/run-clang-tidy.sh
Also, add .clang-tidy configuration file.
In test/syntax_check/CMakeLists.txt, make ETL headers non-system headers.
Added .github/workflow/clang-tidy.yaml. Does not break the build for now
on clang-tidy findings/warnings.
Fix syntax issues
Those issues were uncovered by making ETL headers
non-system headers in test/syntax_checks/CMakeLists.txt
* Fix macro syntax

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.
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
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.
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
* Add development tools to docker image
python3-cogapp, clang-format, treefmt
Add script to run development environment in docker container
Document docker use in docs/docker.md

* 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.
