This was disabled explicitly in recent commit
232c948674cff1b4b72c2d6b3acfa7342d096dd1 to prevent using
the <compare> header from STL.
Now, re-enabling by implementing an ETL version of it in compare.h
* Help the compiler optimize unaligned_type.
This fixes a regression in 266b0f99 when the type was made constexpr. When
switching to a loop to construct the value the compiler was unable to detect
what was going on. We now unroll the loop at compile time into what's
essentially a hand rolled shift and OR operation which the compiler detects
and replaces with a byte swap. Tested on gcc (x86+arm) and clang (x86).
Introduce a static value_from which can be used to convert a value from an
existing buffer. There were previously three options for this, all bad or
awkward in different ways:
- val = etl::be_uint32_t(address)
Copies to temporary storage.
- val = *reinterpret_cast<const etl::be_uint32_t*>(address);
Unreadable.
- etl::be_uint32_t::copy_store_to_value(address, output);
Requires an output parameter.
The new addition is:
- val = etl::be_uint32_t::value_from(address);
Additionally, update the documentation with value_from and the missing,
existing constructors.
* Please clang-format.

Dispatch only the argument types which are actually stated. For everything
else, don't generate the code anymore.
Detemplatize parse_format_spec().
Collapse long double and double to double on targets where they are
same size. This helps prevent duplicate code generation.
Even without ETL_USE_TYPE_TRAITS_BUILTINS in the profile, we get
compiler builtins detected. Makes detection more consistent now.
Previously, some type trait builtins were detected automatically,
and some others needed to be activated via ETL_USE_TYPE_TRAITS_BUILTINS
in the profile explicitly.

Further, switching internal member from array_view to span to
be closer to standard, and more constexpr friendly.
Also adjusting to C++11 template syntax.

Besides, remove unused ASAN_OPTIONS from github workflows.
Further, activate sanitizers for C++23 workflows, at the places
where we also activated -O3 optimization. Not activating everywhere
for CI efficiency reasons for now.
Note that the sanitizers are activated on clang C++23 workflows
only, since there is a remaining issue with GCC in delegate_cpp11.

* Fixed building and unit tests run under XCode 2027 Beta 6 (AppleClang 21.0.0.21000333):
- Compilation failures:
- `etl::ideque::iterator::operator[]` index type should be `difference_type` (instead of `size_t`).
- random-access `etl::poly_span::iterator` is missing `operator[]`.
- Unit tests failures of `test_multimap` suit:
- fixed `equal_range`-related tests to properly verify result range (via new `Check_Equal` overload helper).
- fixed `find`-related tests to not depend on particular order of `second` values (via new `Check_ContainsPair` helper). See note 1,2) at [cppreference](https://cppreference.com/cpp/container/multimap/find) about order.
* PR review fixes.

mutex_freertos.h unconditionally included the vanilla FreeRTOS header
layout (FreeRTOS.h and semphr.h at the include root). On ESP-IDF, and
therefore Arduino-ESP32 as well since it's built on top of ESP-IDF,
these headers are nested one level deeper under freertos/, so the
unconditional include fails to compile on any ESP32 target with
ETL_TARGET_OS_FREERTOS defined.
Use __has_include to try the standard path first, fall back to the
ESP-IDF nested path, and fail with a clear #error if neither is found,
rather than a mysterious "file not found" from the compiler.
Also resolves a pre-existing include-style inconsistency in this file:
the old code mixed "FreeRTOS.h" (quotes) with <semphr.h> (angle
brackets). All includes now uniformly use angle brackets.
* Topic/optional monadic operations
* topic/optional-monadic-operations:
- added and_then, or_else, and transform to etl::optional with unit tests
- added is_optional to optional.h, used in and_then and or_else to ensure that the returned type is an optional
- implemented as ref-qualified overloads with C++11 compatible trailing return types, following the etl::expected implementation
* Convert to C++11 style type traits
* Coderabbit changes
Constrain transform before forming etl::optional<U>.
Remove references from monadic result types.
* clang-format updates

* Adopt the Library Fundamentals TS make_array design for the sequence factories
make_array, make_deque, make_vector, make_list, make_forward_list and
make_indirect_vector now follow the Library Fundamentals TS
std::experimental::make_array design: a defaulted leading template
parameter selects the element type explicitly, falling back to the
decayed common type of the arguments when it is not supplied. A shared
trait (etl::private_make::element_type) performs the selection lazily,
so common_type is not instantiated when the element type is explicit.
This fixes the explicit-element-type calling style for the four
common-type factories, where make_vector<char>(lvalue) never compiled:
the explicit argument pinned the first pack parameter to char, making
it a char&& that no lvalue can bind to. It also gives make_array and
make_deque the deduced form (e.g. make_array(1, 2L) is array<long, 2>)
for free. All arguments are converted with static_cast, as in the
make_array const-lvalue fix, so const-qualified lvalues and narrowing
initialisers work in both forms.
Intentional behaviour change: an explicit element type now converts
every argument instead of pinning only the first. make_vector<char>(0,
1, ...) previously produced vector<int> - the explicit char affected
only the first argument and the element type was still the common type
- and now produces vector<char>. test_make_vector documented the old
behaviour and has been updated.
The keyed set and map factories are unchanged: their key/mapped types
are separate mandatory template parameters ahead of a fully-deduced
pack, so the explicit-type style already works, and retrofitting
deduction there would interact with the defaulted comparator/hash
parameters.
Adds explicit-element-type tests for the four common-type factories
(const/non-const lvalues plus narrowing initialisers) and
deduced-element-type tests for make_array and make_deque, and updates
the four documented signatures.
* Address review comments on the make_xxx factory design
- Forward same-type arguments in the make_xxx factories instead of
casting them. static_cast produced a prvalue that, before C++17, had
to be materialised through the move constructor, rejecting
copyable-but-non-movable element types. The new
private_make::convert helper forwards arguments that already have
the element type and static_casts the rest.
- Drop ETL_NOEXCEPT from make_array: conversions can throw, and the
other factories do not declare it.
- Remove the redundant etl::decay in element_type<void, ...>;
etl::common_type already decays its arguments.
- Stop leaking the etl::private_make implementation namespace into the
documented factory signatures.
* Add a test for make_array with an explicit element type and no arguments
etl::make_array<int>() produces an empty etl::array<int, 0> and now has
a regression test. A call with neither an element type nor arguments
remains ill-formed, matching the Library Fundamentals TS: there is
nothing to deduce the element type from. The array documentation now
states this explicitly.
