// Detect a number of compiler features - by compiler
// The following features are defined:
//
// CATCH_CONFIG_WINDOWS_SEH : is Windows SEH supported?
// CATCH_CONFIG_POSIX_SIGNALS : are POSIX signals supported?
// CATCH_CONFIG_DISABLE_EXCEPTIONS : Are exceptions enabled?
// ****************
// Note to maintainers: if new toggles are added please document them
// in configuration.md, too
// ****************

// In general each macro has a _NO_<feature name> form
// (e.g. CATCH_CONFIG_NO_POSIX_SIGNALS) which disables the feature.
// Many features, at point of detection, define an _INTERNAL_ macro, so they
// can be combined, en-mass, with the _NO_ forms later.

// like `std::string::~string` being called on an uninitialized value.
//
// For example, this code will likely segfault under IBM XL:
// ```
// REQUIRE(std::string("12") + "34" == "1234")
// ```
//
// Similarly, NVHPC's implementation of `__builtin_constant_p` has a bug which
// results in calls to the immediately evaluated lambda expressions to be
// reported as unevaluated lambdas.
// https://developer.nvidia.com/nvidia_bug/3321845.

/** \file
 * Why does decomposing look the way it does:
 *
 * Conceptually, decomposing is simple. We change `REQUIRE( a == b )` into
 * `Decomposer{} <= a == b`, so that `Decomposer{} <= a` is evaluated first,
 * and our custom operator is used for `a == b`, because `a` is transformed
 * into `ExprLhs<T&>` and then into `BinaryExpr<T&, U&>`.
 *
 * In practice, decomposing ends up a mess, because we have to support
 * various fun things.
 *
 * 1) Types that are only comparable with literal 0, and they do this by
 *    comparing against a magic type with pointer constructor and deleted
 *    other constructors. Example: `REQUIRE((a <=> b) == 0)` in libstdc++
 *
 * 2) Types that are only comparable with literal 0, and they do this by
 *    comparing against a magic type with consteval integer constructor.
 *    Example: `REQUIRE((a <=> b) == 0)` in current MSVC STL.
 *
 * 3) Types that have no linkage, and so we cannot form a reference to
 *    them. Example: some implementations of traits.
 *
 * 4) Starting with C++20, when the compiler sees `a == b`, it also uses
 *    `b == a` when constructing the overload set. For us this means that
 *    when the compiler handles `ExprLhs<T> == b`, it also tries to resolve
 *    the overload set for `b == ExprLhs<T>`.
 *
 * To accommodate these use cases, decomposer ended up rather complex.
 *
 * 1) These types are handled by adding SFINAE overloads to our comparison
 *    operators, checking whether `T == U` are comparable with the given
 *    operator, and if not, whether T (or U) are comparable with literal 0.
 *    If yes, the overload compares T (or U) with 0 literal inline in the
 *    definition.
 *
 *    Note that for extra correctness, we check  that the other type is
 *    either an `int` (literal 0 is captured as `int` by templates), or
 *    a `long` (some platforms use 0L for `NULL` and we want to support
 *    that for pointer comparisons).
 *
 * 2) For these types, `is_foo_comparable<T, int>` is true, but letting
 *    them fall into the overload that actually does `T == int` causes
 *    compilation error. Handling them requires that the decomposition
 *    is `constexpr`, so that P2564R3 applies and the `consteval` from
 *    their accompanying magic type is propagated through the `constexpr`
 *    call stack.
 *
 *    However this is not enough to handle these types automatically,
 *    because our default is to capture types by reference, to avoid
 *    runtime copies. While these references cannot become dangling,
 *    they outlive the constexpr context and thus the default capture
 *    path cannot be actually constexpr.
 *
 *    The solution is to capture these types by value, by explicitly
 *    specializing `Catch::capture_by_value` for them. Catch2 provides
 *    specialization for `std::foo_ordering`s, but users can specialize
 *    the trait for their own types as well.
 *
 * 3) If a type has no linkage, we also cannot capture it by reference.
 *    The solution is once again to capture them by value. We handle
 *    the common cases by using `std::is_arithmetic` and `std::is_enum`
 *    as the default for `Catch::capture_by_value`, but that is only a
 *    some-effort heuristic. These combine to capture all possible bitfield
 *    bases, and also some trait-like types. As with 2), users can
 *    specialize `capture_by_value` for their own types as needed.
 *
 * 4) To support C++20 and make the SFINAE on our decomposing operators
 *    work, the SFINAE has to happen in return type, rather than in
 *    a template type. This is due to our use of logical type traits
 *    (`conjunction`/`disjunction`/`negation`), that we use to workaround
 *    an issue in older (9-) versions of GCC. I still blame C++20 for
 *    this, because without the comparison order switching, the logical
 *    traits could still be used in template type.
 *
 * There are also other side concerns, e.g. supporting both `REQUIRE(a)`
 * and `REQUIRE(a == b)`, or making `REQUIRE_THAT(a, IsEqual(b))` slot
 * nicely into the same expression handling logic, but these are rather
 * straightforward and add only a bit of complexity (e.g. common base
 * class for decomposed expressions).

 * Implementation of uniform distribution on floating point numbers.

 * Note that we support only `float` and `double` types, because these
 * usually mean the same thing across different platform. `long double`
 * varies wildly by platform and thus we cannot provide reproducible
 * implementation. Also note that we don't implement all parts of
 * distribution per standard: this distribution is not serializable, nor
 * can the range be arbitrarily reset.
 *
 * The implementation also uses different approach than the one taken by
 * `std::uniform_real_distribution`, where instead of generating a number
 * between [0, 1) and then multiplying the range bounds with it, we first
 * split the [a, b] range into a set of equidistributed floating point
 * numbers, and then use uniform int distribution to pick which one to
 * return.
 *
 * This has the advantage of guaranteeing uniformity (the multiplication
 * method loses uniformity due to rounding when multiplying floats), except
 * for small non-uniformity at one side of the interval, where we have
 * to deal with the fact that not every interval is splittable into
 * equidistributed floats.
 *
 * Based on "Drawing random floating-point numbers from an interval" by
