* 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.

* Corrected the documented make_xxx factory signatures and examples
The Make template sections across the container documentation had
drifted from the implementations, largely through copy-paste:
- map.md, multimap.md and flat-multimap.md all documented
make_flat_map; multiset.md documented make_set; flat-multiset.md
documented make_flat_set; unordered-multimap.md documented
make_unordered_map. Names and examples now match each container.
- Every signature omitted the C++11-required trailing return type
despite the sections being labelled C++11 and above; several also
used a parameter name (TValues) that did not match any template
parameter, and the unordered map headers were missing a comma.
- forward-list.md documented a make_array-style signature with an
explicit element type; the real function deduces the element type as
the common type of the arguments, as documented for make_list.
- The flat_set/flat_multiset template headers were missing the
variadic parameter pack, and their examples passed a braced list to
a variadic function, which does not compile; set.md used TKeyCompare
where the implementation uses TCompare.
- deque.md and the reference container docs were missing code fences.
- Updated the four reference_flat_* function. However these functions
cannot be instantiated at all (the reference containers have no
initializer_list constructor, since one would dangle by design), so
the documented examples have never compiled.
Every remaining documented example verified to compile with clang 22
(C++17) against the current headers.
* Fixed C++17-only syntax in factory examples and flagged the non-compilable ones
Review feedback on the make_xxx documentation examples:
- All the map-family factory examples are labelled C++11 and above but
constructed their pairs with class template argument deduction
(etl::pair{0, 1}), which requires C++17. The pairs in the make_flat_map,
make_flat_multimap, make_map, make_multimap, make_unordered_map,
make_unordered_multimap, make_reference_flat_map and
make_reference_flat_multimap examples now name their template arguments
explicitly. The template deduction guide examples are unchanged, as
those sections are labelled C++17 and above. Verified with clang 22 in
C++14 mode, which, like C++11, has no deduction guides.
- The four make_reference_flat_* examples are now preceded by a warning
callout stating that they do not currently compile: the functions
cannot be instantiated because the reference containers have no
initializer_list constructor. The examples themselves are retained,
rewritten to pass named lvalues rather than temporaries, since the
reference containers store references to external objects and the
temporaries would dangle even if the functions compiled. The defect
is being reported separately.

make_list was the only make_xxx container factory taking its argument
pack by value rather than by forwarding reference, costing an extra
move per lvalue argument: each lvalue was copy-constructed into the
parameter and then moved into the initializer_list backing array,
where the forwarding-reference signature copies it there directly.
Rvalue prvalue arguments count the same either way in practice, as
copy elision constructs them directly into the by-value parameter.
Change the pack to T&&..., matching make_vector, make_forward_list and
make_indirect_vector. The deduced reference types decay through
common_type, so the element type deduction is unchanged.
Adds tests for const/non-const lvalues of the element type (guarding
against the forward<T> defect fixed for make_array and make_deque),
mixed-type common_type deduction, and an instrumented type counting
copy/move constructions, which fails with the by-value signature (one
extra move per lvalue argument) and passes with the fix.
Also corrects the make_list documentation, which described a
make_array-style signature with an explicit element type parameter
that never matched the implementation.
Verified with clang 22 (C++17): all 93 list tests pass; C++14/20
syntax checks pass.
Note: mixed-type lvalue arguments are affected by a separate
pre-existing defect in etl::common_type (its two-type specialization
recurses with decay<T2> twice instead of decay<T1>, decay<T2>), which
already affects the other common_type-based factories and is being
fixed separately.

Fix etl::mem_cast cross-size copy constructor and assignment (#1488)
The templated cross-size copy constructor and assignment operator were
broken in two ways:
- They accessed other.buffer / rhs.buffer, which is private in a
different mem_cast instantiation, so the cross-size overloads failed
to compile whenever they were actually instantiated.
- They copied Size_ (the destination size) bytes from a source buffer
that is only Other_Size bytes large, reading past the end of the
source when the destination was larger.
Use the public data() accessor and copy Other_Size bytes. The existing
static_assert(Size >= Other_Size) guarantees the destination is big
enough.
Add test_mem_cast_copy_and_assign_from_smaller regression test.

Fix etl::pearson::reset() not resetting the first-byte flag (#1487)
reset() cleared the hash array but left the `first` flag false, so a
calculator reused after reset() took the XOR update path on its next
add() instead of the initialisation path. This produced an incorrect
hash for any pearson object that was reset and reused.
Reset `first` to true in reset() so a reset calculator behaves like a
freshly constructed one.
Add test_pearson_reset regression test.

Fix etl::bitset single-element from_string shift on empty string (#1486)
The single-element from_string overloads (char, wchar_t, char16_t,
char32_t) computed element_type(1) << (string_length - 1U) before the
copy loop. For an empty string, or when active_bits is 0, string_length
is 0, so the shift count underflows to SIZE_MAX. Shifting by more than
the element width is undefined behaviour, which also breaks constexpr
evaluation.
Guard the mask with a zero-length check so the shift is only performed
when string_length > 0. The multi-element from_string overloads were
already safe.
Add test_construct_from_empty_string regression test.

Fix etl::histogram copy/move not preserving start_index (#1485)
The run-time-offset specialization of etl::histogram stores a start_index
member used to map keys to bins (accumulator[key - start_index]). Its copy
constructor, move constructor, copy assignment, and move assignment copied
only the accumulator and left start_index uninitialized, so a copied or
moved histogram indexed the wrong bin in operator[]/add(), causing
out-of-bounds access (undefined behavior).
All four special member functions now also copy start_index. The
compile-time-offset specialization is unaffected, as its start index is a
template constant rather than a data member.
Add regression tests covering copy/move construction and assignment.

Fix etl::message_timer firing following timers early on unregister (#1484)
active_list.remove(id, has_expired) adjusts the next timer's delta only
when has_expired is false. When unregistering an active, non-expired timer,
unregister_timer() incorrectly passed true, skipping that adjustment, so
every timer after the removed one in the active list fired early by the
removed timer's delta.
Pass false instead, matching the etl::callback_timer family. tick() still
passes true, since the timer has genuinely expired there. The bug affected
all four variants: message_timer, message_timer_interrupt,
message_timer_atomic and message_timer_locked. Existing tests missed it
because they only ever unregistered the tail timer, where the delta
adjustment is a no-op.
Add a regression test that unregisters a non-tail active timer and checks
the following timer still fires at its original absolute time.

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.
